POS Line Card Product Numbers
Table 1 lists the Cisco product numbers to which this publication applies. This guide replaces the individual POS line card installation and configuration documents for the Cisco 12000 Series Router.
Router Hardware Installation
For hardware installation and configuration information for Cisco 12000 Series Routers, refer to the installation and configuration guide for your router. The guide includes information on the router switch fabric and how it affects operation of the line card, as well as line card slot locations, slot width, and other requirements.
Also refer to the field-replaceable unit (FRU) publications that describe how to install, maintain, and replace router subsystems, such as cooling fans, power supplies, chassis backplanes, and so on.
Supported Platforms
Table 2 lists the supported router platforms for POS line cards.
Note To support Engine 4 or Engine 6 line cards, Cisco 12400 and 12800 Routers must have a full set of switch fabric, specifically, one clock scheduler card (CSC) and three switch fabric cards (SFCs), or five SFCs for a Cisco 12410 or 12810 Router. (Engine 6 line cards can operate in a Cisco 12800 Router only.)
Engine 0, 1, 2, and 3 line card families will operate in a router with one CSC and three SFCs. Only Engine 0 line cards will operate if the switch fabric is degraded, for example, one CSC and two SFCs.
See Table 29 for information on the engine of each line card. See the appropriate Cisco 12000 Series Router installation and configuration guide for information about the switch fabric and other related requirements.
Cisco IOS Software Release and Hardware Revision Requirements
To ensure compatibility with the software, your POS line card should have a specific hardware revision number. This number is printed on a label affixed to the component side of the card. The hardware revision number can also be displayed using the show diags slot-number command.
Table 3 lists the Cisco IOS releases that are compatible with each of the POS line cards as well as their minimum hardware requirements.
The show version and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running. For complete descriptions of show commands, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Configuration Fundamentals Command Reference for the installed Cisco IOS release.
If the command displays indicate that the Cisco IOS software is a version earlier than you need, check the contents of flash memory to determine if the required images are available on your system. The dir devicename command displays a list of all files stored in flash memory. If you do not have the correct software version, contact Cisco customer service.
For software configuration information, refer to the Cisco IOS software configuration and command reference publications for the installed Cisco IOS release. Also refer to the Cisco IOS software release notes for additional information.

Preparing for Installation
The following sections provide information about preparing to install line cards:
•Preventing Electrostatic Discharge
Safety Guidelines
Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.
The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.
Note Review the safety warnings listed in the Regulatory Compliance and Safety Information for Cisco 12000 Series Internet Router publication (Document Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining a line card.
•Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to enter into any laser-based components.
•Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with line cards.
•Cisco equipment operates safely when it is used in accordance with its specifications and product usage instructions.
Before working with laser optics, see the "Laser Safety" section.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap whenever you are handling network equipment or one of its components.
The following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect the equipment end of the connection cord to an ESD connection socket on the router or to bare metal on the chassis.
•Handle POS line cards by the captive installation screws, the provided handle, ejector levers, or the line card metal carrier only; avoid touching the board or connector pins.
•Place removed POS line cards board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.
•Avoid contact between the POS line cards and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Warning For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1 and 10 megohms.
Required Tools and Equipment
You need the following tools and parts to remove and install POS line cards:
•Flat-blade or Phillips screwdriver
•ESD-preventive wrist or ankle strap and instructions
•Interface cables to connect the POS line card with another router or switch
•Any SFP modules or memory you need to install that are not already installed
Note If you need additional equipment, see Cisco.com or your service representative for ordering information.
Refer to the individual line card descriptions in the "Product Overviews" section for more information. Table 4 summarizes the hardware requirements for each POS line card.
See the "Line Card Interface Cables" section for information on required interface cables.

Note See the "Guidelines for Line Card Removal and Installation" section before removing a line card while power to the router is on.
Note The procedures in the following sections use illustrations of a Cisco 12012 Router to support the descriptions of removing and installing line cards. Although the card cages of the Cisco 12000 Series Routers differ in the number of card slots, the designated use of slots and the process of removing and installing a line card are basically the same. Therefore, separate procedures and illustrations for other Cisco routers are not included in this publication.
Guidelines for Line Card Removal and Installation
Guidelines for line card removal and installation include the following:
•Online insertion and removal (OIR) is supported, enabling you to remove and install line cards while the router is operating. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation.
Note With OIR, notifying the software or resetting the power is not required. However, you have the option of using the shutdown command before removing a line card.
•After you reinstall a line card, the router automatically downloads the necessary software from the route processor (RP). Next, the router brings online only those interfaces that match the current configuration and were previously configured as administratively up. You must configure all others with the configure command.
Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.
After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or inserting another line card.
•Line cards have two ejector levers to release the card from its backplane connector. Use the levers when you are removing the line card and to seat the line card firmly in its backplane connector when you are installing the line card. The ejector levers align and seat the card connectors in the backplane.
Caution When you remove a line card, always use the ejector levers to ensure that the connector pins disconnect from the backplane in the sequence expected by the router. Any card that is only partially connected to the backplane can halt the router.
When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector; the connector pins should make contact with the backplane in the correct order, indicating that the card is fully seated in the backplane. If a card is only partially seated in the backplane, the router will hang and subsequently crash.
For line card configuration information, see the "Configuring and Troubleshooting Line Card Interfaces" section.
Removing a Line Card
If you are replacing a failed line card, remove the existing line card first, then install the new line card in the same slot. To remove a line card, use Figure 21 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Disconnect and remove all interface cables from the ports; note the current connections of the cables to the ports on the line card.
Step 3 Detach the line card cable-management bracket from the line card.
Step 4 Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 21a.)
Figure 21 Line Card Removal and Installation
Caution When you remove a line card, always use the ejector levers to ensure that the line card connector pins disconnect from the backplane in the logical sequence expected by the router. Any line card that is only partially connected to the backplane can halt the router.
Step 5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane connector. (See Figure 21b.)
Step 6 Grasp the ejector levers and pull the line card halfway out of the slot.
Step 7 Grasp the line card and gently pull it straight out of the slot, keeping your other hand under the line card to guide it. (See Figure 21c.) Avoid touching the line card printed circuit board, components, or any connector pins.
Step 8 Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan to return it to the factory.
Step 9 If the line card slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK) to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure the line card blank to the chassis by tightening its captive screws.
Note The following warning applies to removing very-short-reach line cards.
Warning Class 1M laser radiation when open. Do not view directly with optical instruments.
Caution Be careful not to damage or disturb the EMI spring fingers located on the front edge of the card face plate.
Note Always insert a dust plug in an optical port opening for each port that is not in use.
For information on disconnecting interface cables, see the "Removing and Installing Interface Cables" section.
For information on removing the cable-management bracket, see the "Line Card Cable-Management Bracket" section.
Installing a Line Card
A line card slides into almost any available line card slot and connects directly to the backplane. If you install a new line card, you must first remove the line card blank from the available slot.
Note Refer to the installation and configuration guide for your router for information on line card slot types, slot width, and slot location.
Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.
To install a line card, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Choose an available line card slot for the line card, and verify that the line card interface cable is long enough for you to connect the line card with any external equipment.
Caution To prevent ESD damage, handle line cards by the captive installation screws, the provided handle, ejector levers, or the card carrier edges only. Do not touch any of the electrical components or circuitry.
Step 3 Grasp the faceplate (or handle) of the line card with one hand and place your other hand under the card carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid touching the line card printed circuit board, components, or any connector pins.
Step 4 Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting the line card until the ejector lever hooks are fully latched. (See Figure 22.)
Figure 22 Ejector Levers
Caution When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the router to hang and subsequently crash.
Step 5 Simultaneously pivot both ejector levers toward each other until they are perpendicular to the line card faceplate. This action firmly seats the card in the backplane.
Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the captive screw on each end of the line card faceplate to ensure proper EMI shielding and to prevent the line card from becoming partially dislodged from the backplane.
Caution To ensure adequate space for additional line cards, always tighten the captive installation screws on each newly installed line card before you insert any additional line cards. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the router.
Step 7 Install the cable-management bracket.
Step 8 Install GBIC or SFP modules, and EPA daughter cards, in the line cards that use them.
Step 9 Install the interface cables.
For information on installing cable-management brackets, see the "Installing a Line Card Cable-Management Bracket" section.
For information on installing SFP modules, see the "Removing and Installing SFP Modules" section.
For information on installing interface cables, see the "Removing and Installing Interface Cables" section.
For information on verifying and troubleshooting the hardware installation, see the "Verifying and Troubleshooting the Line Card Installation" section.
Removing and Installing SFP Modules
Before you remove or install an SFP module, read the installation information in this section and the "Laser Safety" section.
POS line cards use various optics and connectors. See the "Cabling and Specifications" section for optics and cabling specifications.
Before removing SFP modules, you must first disconnect any connected interface cables. See the "Removing and Installing Interface Cables" section.
Caution Protect the SFP modules by inserting clean dust covers into them after the cables are removed. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another SFP module. Avoid getting dust and other contaminants into the optical ports of your SFP modules: The optics will not work correctly when obstructed with dust.
Caution Removing and inserting an SFP module can shorten its useful life, so remove and insert them only when absolutely necessary.
SFP modules use one of four different latching devices to install and remove the module from a port. The four types of SFP module latching devices are described in the following sections:
Bale Clasp SFP Module
The bale clasp SFP module has a clasp that you use to remove or install the SFP module. (See Figure 23.)

If the SFP module was not completely seated and secured in the receptacle, you will hear a click as the triangular pin on the bottom of the SFP module snaps into the hole in the receptacle.
Line Card Cable-Management Bracket
Note The illustrations in this section show various line cards, but the line card cable-management bracket installation procedure is the same regardless of the specific line card.
Cisco 12000 Series Routers include a cable-management system that organizes the interface cables entering and exiting the router, keeping them out of the way and free of sharp bends.
Caution Excessive bending of interface cables can damage the cables.
The cable-management system consists of two separate components:
1. A cable-management tray that is mounted on the chassis. Refer to the appropriate Cisco 12000 Series Router installation and configuration guide for more information on the cable-management tray.
2. A cable-management bracket that attaches to a line card.
This section describes the line card cable-management bracket. Figure 36 shows the single-port line card cable-management bracket; Figure 37 shows the multiport line card cable-management bracket.
Figure 36 Single-Port Line Card Cable-Management Bracket
Figure 37 Multiport Line Card Cable-Management Bracket
Note When shipped with spare line card orders, the cable-management bracket is not attached to the line card. You must attach the cable-management bracket to the line card before you insert the line card into the router.
Caution Do not use the cable-management bracket as a handle to pull out or push in the line card. The cable-management bracket is designed to hold the interface cables and may break if you use the bracket to push, pull, or carry the line card after it is removed from the router.
The 2-Port OC-192c/STM-64c POS line card uses the single-port line card cable-management bracket. When more than two fibers are used, they should not loop through the rubber hook, but should pass through the bracket as shown in Figure 38.
Figure 38 Single-Port Line Card Cable-Management Bracket with Multiple Fibers
Removing and installing the line card cable-management bracket is described in the following procedures:

Cabling and Specifications
The following sections provide informaton about specifications and cabling for POS line cards:
•Power Budget and Signal Specifications
Packet-Over-SONET Interface
POS is a high-speed method of transporting Internet Protocol (IP) traffic between two points. This technology combines the Point-to-Point Protocol (PPP) with Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) interfaces.
PPP was designed as a standard method of communicating over point-to-point links. Initial deployment was over short local lines, leased lines, and plain-old-telephone-service (POTS) (also called basic telephone service) for users of modems. As new packet services and higher speed lines are introduced, PPP can be deployed easily in these environments as well.
SONET is an octet-synchronous multiplex scheme defined by the American National Standards Institute (ANSI) standard (T1.1051988) for optical digital transmission at hierarchical rates from 51.840 Mbps to 2.5 Gbps (Synchronous Transport Signal, STS-1 to STS-48) and greater. SDH is an equivalent international standard for optical digital transmission at hierarchical rates from 155.520 Mbps (STM-1) to 2.5 gigabits per second (Gbps) (STM-16) and greater. SONET electrical specifications have been defined for single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. (For example, the 4-port OC-3c/STM-1c POS line card allows transmission over single-mode and multimode optical fiber at Optical Carrier 3 [OC-3] rates. OC-3 is the Optical Carrier 3 specification for SONET STS-3c and SDH STM-1 transmission rates.)
SONET/SDH transmission rates are integral multiples of 51.840 Mbps. The following transmission multiples are currently specified and commonly used:
•OC-3c/STM-1c—155.520 Mbps
•OC-12c/STM-4c—622.080 Mbps
•OC-48c/STM-16c—2488.320 Mbps
•OC-192c/STM-64c—9953.280 Mbps
The POS specification (RFC 1619) describes the use of PPP encapsulation over SONET/SDH links. Because SONET/SDH is, by definition, a point-to-point circuit, PPP is well-suited for use over these links. PPP treats SONET/SDH transport as octet-oriented full-duplex synchronous links. PPP presents an octet interface to the physical layer. The octet stream is mapped into the SONET/SDH Synchronous Payload Envelope (SPE), with the octet boundaries aligned with the SPE octet boundaries. The PPP frames are located by row within the SPE payload. Because frames are variable in length, the frames are allowed to cross SPE boundaries.
The basic rate for POS is OC-3/STM-1, which is 155.520 Mbps. The available information bandwidth is 149.760 Mbps, which is the OC-3c/STM-1 SPE with section, line, and path overhead removed.
Power Budget and Signal Specifications
The SONET specification for fiber-optic transmission defines two types of fiber: single-mode and multimode. Signals can travel farther through single-mode fiber than through multimode fiber.
The maximum distance for installations is determined by the amount of light loss in the fiber path. If your environment requires the signal to travel close to the typical maximum distance, you should use an optical time domain reflectometer (OTDR) to measure the power loss.

Good quality single-mode fiber with very few splices can carry an OC-3c/STM-1c signal 9.3 miles (15 km) or more. Good quality multimode fiber can carry a signal up to 1.3 miles (2 km). If your environment requires the signal to travel close to the typical maximum distance (as listed in Table 9), use an OTDR to measure the power loss.
Caution If you use a loopback cable with the single-mode line cards, use a loopback cable with a minimum 10 dB attenuator to avoid damage to the parts.
OC-3c/STM-1c ISE POS Line Card Power Specifications
All OC-3c/STM-1c ISE POS line cards provide155 Mbps laser-based SONET/SDH-compliant interfaces. Table 10 lists the power ratings and distances of each line card. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.

Each SFP contains an internal serial number that is security-programmed by the SFP manufacturer with information that provides a way for Cisco (through the Cisco IOS software) to identify and validate the SFP as a module type that is qualified by Cisco to operate with 8-Port OC-48c/STM-16c POS line cards. Unapproved SFP modules (those not purchased directly from Cisco) will not work.
OC-192c/STM-64c POS Line Card Power Specifications
Table 21 lists the power ratings and distances of each line card by optical transceiver type. If your environment requires the signal to travel close to the typical maximum distance, you should use an OTDR to measure the power loss.
All OC-192c/STM-64c POS line cards provide a full-duplex, 10-Gbps, laser-based SONET/SDH-compliant interface. When equipped with very-short-reach optics, the OC-192c/STM-64c POS line card VSR physical layer is not SONET/SDH-compliant at the physical layer, but is compliant with the Optical Internetworking Forum VSR implementation agreement VSR4-01. When equipped with long-reach optics, the OC-192c/STM-64c POS line card LR physical layer is based on the SONET/SDH physical layer, but with an offset power budget to account for available technology limitations.
All versions of the line card meet both the EN60825\IEC60825 and FDA - Code of Federal Regulations (USA) laser safety standards.

Line Card Interface Cables
The following types of cables are used with POS line cards to connect your router to another router or switch:
•Single-mode—Generally yellow in color.
•Multimode—Generally gray or orange in color. Multimode cables are also multifiber cables that carry 12 channels of fiber data.
Note Fiber cables are not available from Cisco Systems. They can be purchased from cable vendors. The plug on the cable may be supplied with a dust cover. If it is, remove it before trying to connect it to the line card port.
The following types of cable connectors are used with POS line cards:
•Subscriber connector (SC)—See Figure 41 and Figure 42.
•Multiple terminations push-pull latch (MTP)—See Figure 43.
•Lucent connector (LC)— See Figure 44.
•Fiber connector (FC)—See Figure 45. FC connectors do not have a spring-action disconnect latch.
•Mechanical transfer registered jack (MTRJ) connector—See Figure 46.

To remove an interface cable, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap to your wrist and follow its instructions for use.
Step 2 Press on the spring-action disconnect latch to disconnect the cable from the interface ports. (See Figure 41 through Figure 45.) FC connectors do not have a spring-action disconnect latch.
Step 3 Slowly pull the connector from the port.
Warning Invisible laser radiation can be emitted from the aperture of the port when no cable is connected. Avoid exposure to laser radiation and do not stare into open apertures.
Warning Class 1 laser product (single-mode).
Warning Class 1 LED product (multimode).
Step 4 Insert a dust plug into the optical port openings of each interface that is not being used.
To install an interface cable, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap to your wrist and follow its instructions for use.
Step 2 Remove the connector dust cover, if one is present.
Step 3 Align the connector end of the cable to the appropriate port. Observe the receive (RX) and transmit (TX) cable relationship, as shown in Figure 47.

Step 4 Insert the connector until it clicks and locks into place.
Note The fiber-optic connectors must be free of dust, oil, or other contaminants. Carefully clean the fiber- optic connectors using an alcohol wipe or other suitable cleanser.
Verifying and Troubleshooting the Line Card Installation
The following sections describe how to verify and troubleshoot line card installation:
•Troubleshooting the Installation
Initial Boot Process
Note Many new line cards are designated as administratively down by default. Status LEDs are off until you configure the interfaces and use the no shutdown command.
During a typical line card boot process, the following events occur:
1. The line card maintenance bus (MBus) module receives power and begins executing the MBus software.
2. The line card MBus module determines the type of card on which it resides, performs internal checks, and prepares to accept the Cisco IOS software from the RP.
3. The RP powers up the line card and loads the line card with its Cisco IOS software.
To verify that the line card is working properly, perform the following operational checks:
•During the line card boot process, observe the line card alphanumeric LEDs to ensure that the card is running the typical initialization sequence. The sequence should end with IOS RUN.
•Observe the line card status LEDs to verify that the Active LED (Link LED or status LED for line cards with no Active LED) is on. If an Active LED is not on, verify that the associated interface is not shut down.
If one of these conditions is not met, refer to the "Advanced Line Card Troubleshooting" section to identify any possible problems.
Alphanumeric LEDs
POS line cards have two four-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever, that display a sequence of messages indicating the state of the card. In general, the LEDs do not turn on until the RP recognizes and powers up the card. As it boots, the line card displays a sequence of messages similar to those in Table 24.
Note It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in Table 24 and Table 25 may not appear on your line card.

Status LEDs
Interface status LEDs show the status of each fiber-optic connector. POS line cards contain the following status LEDs:
•Active—Indicates the active condition of this port
•Carrier—Indicates the status of SONET framing reception on this port
•RX PKT or RX Packet—Indicates the status of packet reception on this port. It flashes when data is being received.
The status LEDs might not go on until after you have configured the line card interfaces (or turned them on, if they were shut down). To verify correct operation of each interface, complete the configuration procedures for the line card. (See the "Configuring and Troubleshooting Line Card Interfaces" section.)
The different operating states of the status LEDs are shown in Table 26 and Table 27.

Troubleshooting the Installation
Note Many new line cards are designated as administratively down by default. Status LEDs are off until you configure the interfaces and use the no shutdown command.
If the Active LED (Link LED or status LED for line cards with no Active LED) or the alphanumeric display LEDs on a line card do not go on, there is either a problem with the line card installation or a hardware failure. To verify that the line card is installed correctly, follow these steps:
Step 1 If the Active LED fails to go on, but the alphanumeric display LEDs on the line card indicate activity, verify that the initialization sequence ends with IOS RUN. If this is the case, verify that the interface is not shut down. If it is not, suspect a circuitry problem with the Active LED and contact a service representative for further assistance.
Step 2 If the Active LED on the line card fails to go on or the alphanumeric display LEDs do not indicate IOS RUN, check the router connections as follows:
a. Verify that the line card board connector is fully seated in the backplane. Loosen the captive installation screws and firmly pivot the ejector levers toward each other until both are perpendicular to the line card faceplate. Tighten the captive installation screws.
b. Verify that all power cords and data cables are firmly connected at both ends.
c. Verify that all memory modules on the card are fully seated and secured to their sockets.
After the line card reinitializes, the Active LED on the line card should go on. If the Active LED goes on, the installation is complete; if the Active LED does not go on, proceed to the next step.
Step 3 If the Active LED still fails to go on, remove the POS line card and try installing it in another available line card slot.
•If the Active LED goes on when the line card is installed in the new slot, suspect a failed backplane port in the original line card slot.
•If the Active LED and alphanumeric display LEDs still do not go on, halt the installation. Contact a service representative to report the faulty equipment and obtain further instructions.
Step 4 If an error message displays on the console terminal during the line card initialization, see the appropriate reference publication for error message definitions. If you experience other problems that you cannot solve, contact a service representative for assistance.
For more information on troubleshooting and diagnostics, refer to the installation and configuration guide that came with your Cisco 12000 Series Router.
Note If you perform online insertion or removal of the GBIC or SFP without shutting down the interface, a warning message is displayed on the console device.
SONET/SDH Clocking Issues
This section provides an overview of SONET/SDH clocking issues. A POS line card supports both line and internal clocking functions. Line clocking is derived from the incoming signal from a given port. Internal clocking is derived from the clock that is internal to the line card.
Each port can be configured independently of any other in a line-timed setup, going back as far as the first payload processor. However, on a POS line card, the second level of payload processing ties the ports to a common clock source which is timed from only one port. This can result in pointer justifications if the remaining ports are not synchronous. However, with a properly configured router, these pointer justifications can be limited to provide the same performance as a SONET cross-connect device.
Note Pointer justifications do not affect data throughput. All configurations of a POS line card provide total data throughput regardless of pointer justifications. Under no circumstances does any data loss occur. All configurations provide 100 percent error-free data flow.
The line card uses Stratum3 (S3) as the internal clock reference. However, if one of the ports is Stratum1 (S1) accurate, it can be used as the local reference for the system clock. In this case, pointer justifications are very limited. If the system clock is timed from an S1 clock source, from a valid SONET network, then there will be no pointer justifications on any synchronous interface. There are minimal pointer justifications (limited to S1 pointer justifications) on any asynchronous interface if it is on another SONET network. Pointer justification in this case is proportional to the accuracy of the other port clock.
A POS line card has the ability to select an input port as the source of synchronization for the system clock. This eliminates pointer justifications on any port that is synchronous with the selected port. Any other port on that line card that is not synchronous to the selected reference port will encounter pointer justifications at a rate proportional to clock accuracy of the port.
If the port is locally timed, it is Stratum3. If the port is line-timed, it depends on the attached network. It could be another Stratum3 clock, a Stratum1, or something much worse. This issue only applies to multiport cards and can be avoided if all ports on the line card are connected to the same SONET/SDH network.
Configuring and Troubleshooting Line Card Interfaces
The following sections detail how to configure and troubleshoot line card interfaces:
•Verifying Software and Hardware Versions
•Line Card Alarm and Event Detection
•POS Line Card Configuration Examples
•Advanced Line Card Troubleshooting
•Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later
•Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S
Initial Configuration
After you verify that a new line card is installed correctly (the Active LED goes on), you can configure it. First, enter the privileged level of the EXEC command interpreter (privileged EXEC mode) by using the enable command. The system will prompt you for a password if one is set. Next, use the configure command to access configuration mode. If you want to change the default configuration values on the line card, use the configure terminal command to enter global configuration mode. Then, use the interface command to specify the interface and enter interface configuration mode, where you can configure the new interface. Be prepared with the information you will need, such as the interface IP address.
A Cisco 12000 Series Router identifies an interface address by its line card slot number and port number, in the format slot/port. For example, the slot/port address of an interface on a 2-Port OC-192c/STM-64c POS line card installed in line card slot 2 and port 0 is 2/0.
Table 28 lists some configuration commands you may want to use and the default values. Refer to Cisco IOS documentation for complete information about these commands.

Configuring The Interface
The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. This process may vary depending on the requirements for your router configuration.
To configure a POS line card, follow these steps:
Step 1 Enter privileged EXEC mode:
Router> enableIf the system prompts you for a password, enter it.
Step 2 Confirm that the router recognizes the line card by entering the show version command:
Router# show versionStep 3 Check the status of each port by entering the show interface command:
Router# show interfaceStep 4 Enter configuration mode by entering the configure terminal command and specify that the console terminal is the source of the configuration subcommands:
Router# configure terminalStep 5 Enable IP routing by entering the ip routing command:
Router(config)# ip routingStep 6 Specify the new interface to configure by entering the interface command, followed by the type (pos) and slot/port (line card slot number/port number). The example that follows is for an OC-192c/STM-64c POS line card in line card slot 1:
Router(config)# interface pos 1/0Step 7 Assign an IP address and subnet mask to the interface using the ip address configuration subcommand:
Router(config-if)# ip address 10.1.2.3 255.0.0.0Step 8 Verify that HDLC encapsulation is correct for this interface. If you need to change the encapsulation, use the encapsulation command:
Router(config-if)# encapsulation encapsulation-typewhere encapsulation-type is one of the keywords hdlc or ppp.
Step 9 Verify that the default value for clock source is correct. The default value is line and is used whenever clocking is derived from the network.
The clock source internal command is typically used when two Cisco 12000 Series Routers are connected back-to-back, or are connected over dark fiber where a clocking source is not available. In either case, each device should have its clock source set to internal.
Router(config-if)# clock source {line | internal}Step 10 Change the shutdown state to up and enable the interface using the no shutdown command:
Router(config-if)# no shutdownThe no shutdown command passes an enable command to the POS line card. It also causes the line card to configure itself based on the previous configuration commands sent.
Step 11 Turn on or off keepalive messages as desired:
Router(config-if)# keepaliveCisco 12000 Series Routers do not require keepalive messages, but they are useful for encapsulated protocols such as HDLC. The keepalive default is on.
Step 12 Turn off the Cisco Discovery Protocol (CDP) using the no cdp enable command:
Router(config-if)# no cdp enable
Note Cisco 12000 Series Routers do not require CDP.
Step 13 Turn off IP multicast fast switching using the no mroute-cache command:
Router(config-if)# no mroute-cache
Note The line card cable is connected to both a Cisco 12000 Series Router device and another device—a high-end router or switch. Step 11 to Step 13 applies to both the Cisco 12000 Series Router device and the other device.
Step 14 Set the cyclic redundancy check (CRC) value to 32 (on both devices) using the crc 32 command:
Router(config-if)# crc 32
Note If the device to which the line card cable is attached does not support a CRC value of 32, set both devices to use a value of 16 by entering the command crc 16.
Step 15 Add any other configuration subcommands required to enable routing protocols and adjust the interface characteristics.
Step 16 After including all the configuration subcommands to complete the configuration, enter Ctrl-Z (hold down the Control key while you press Z) to exit configuration mode.
Step 17 Write the new configuration to memory:
Router# copy running-config startup-configThe router displays an OK message when the configuration is stored.
After you have completed your configuration, you can check it using show commands. For an explanation of show commands, see the "POS Line Card Configuration Examples" section.
Verifying Software and Hardware Versions
The show version, show diag slot_number, and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running, and the hardware revision number. Table 3 lists the required versions for each line card. For complete descriptions of show commands, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Configuration Fundamentals Command Reference for the installed Cisco IOS release.
In the following example of the show version command, the Cisco IOS software version is displayed in italics.

The dir devicename command displays a list of all files stored in flash memory. If you do not have the correct software version, contact Cisco customer service.
Line Card Alarm and Event Detection
The POS line cards do not have an LED for alarm and event detection, but you can enter the show controllers pos EXEC command to verify whether the alarm and event detection messages are active or inactive. Most alarm and event detection messages are short-lived, because if problems occur, the line card clears the error condition, but records the event to verify line card operation status.
Some of the alarm and signal events for the line card are enabled for reporting by default. Others can be enabled individually. The show controllers pos privileged EXEC command output display depends on the configuration of the POS port.
The following partial output example from the show controllers pos privileged EXEC command shows alarm and event information for the second POS controller in slot 2 of a Cisco 12000 Series Router:

Advanced Line Card Troubleshooting
This section provides advanced troubleshooting information in the event of a line card failure. It also provides pointers for identifying whether or not the failure is hardware related. This section does not include any software-related failures, except for those that are often mistaken for hardware failures.
Note This section assumes that you possess basic proficiency in the use of Cisco IOS software commands.
By reading this section and by following the troubleshooting steps, you should be able to determine the nature of the problems you are having with your line card. The first step is to identify the cause of the line card failure or console errors that you are seeing. To discover which card may be at fault, it is essential to collect the output from the following commands:
•show context summary
•show logging
•show logging summary
•show diag slot
•show context slot slot
Along with these show commands, you should also gather the following information:
•Console Logs and Syslog Information—This information is crucial if multiple symptoms are occurring. If the router is configured to send logs to a Syslog server, you may see some information on what has occurred. For console logs, it is best to be directly connected to the router on the console port with logging enabled.
•Additional Data—The show tech-support command is a compilation of many different commands, including show version, show running-config, and show stacks. This information is required when working on issues with the Cisco Technical Assistance Center (TAC).
Note It is important to collect the show tech-support data before doing a reload or power cycle. Failure to do so can cause all information about the problem to be lost.
Note Output from these commands will vary slightly depending on which line card you are using, but the basic information will be the same.
Output Examples
The following are examples of system output that you may see if your Cisco 12000 Series Router line card fails. Key data in the output is underlined.

The three most common types of line card failures are:
•Software Forced Crash (SIG=23)
•Bus Error (SIG=10)
•Cache Parity Exception (SIG=20)
In the example above, the line card has failed and has caused a reload because of a software forced crash exception. Once you have determined the cause and collected the necessary output, you can check for any caveats in your Cisco IOS software release using the Bug Toolkit (available to registered Cisco.com users only).
Checking the Current Status of the Line Card
Once you have determined if the problems are caused by system errors in the log or an actual crash, it is important to check the current status of the line card to see if it has recovered from the failure. The status of individual line cards can be identified either by examining the alphanumeric LEDs located on the front of the line card, or by issuing the show led command.
show led Output
Router# show led
SLOT 1 : RUN IOSSLOT 6 : DNLD FABLSLOT 7 : RP ACTVSLOT 10 : RUN IOSSLOT 11 : RUN IOSSLOT 13 : RUN IOSSLOT 14 : RUN IOS
Note It is possible for the value of an alphanumeric LED to be reversed. For example, IOS RUN may be displayed as RUN IOS.
If the alphanumeric LEDs on the line card display anything other than IOS RUN, or the RP is neither the active Master/Primary nor the Slave/Secondary, there is a problem and the line card has not fully loaded correctly. Before replacing the line card, try fixing the problem by following these steps:
Step 1 Reload the microcode using the global configuration microcode reload slot command.
Step 2 Reload the line card using the hw-module slot reload command. This causes the line card to reset and download the MBus and fabric downloader software modules before attempting to download the Cisco IOS software.
or
Step 3 Reset the line card manually. This may rule out any problems that are caused by a bad connection to the MBus or switching fabric.
Fabric Ping Failure
Fabric ping failures occur when either a line card or the secondary RP fails to respond to a fabric ping request from the primary RP over the switch fabric. Such failures are a problem symptom that should be investigated. They are indicated by the following error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure%LCINFO-3-CRASH: Line card in slot 1 crashedYou can find more information about this issue on Cisco.com in the Troubleshooting Fabric Ping Timeouts and Failures on the Cisco 12000 Series Internet Router publication.
Error Messages
If you receive any error message related to a line card, you can use the Error Message Decoder Tool (on Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This publication does not cover all these messages.
Note Some messages related to Cisco Express Forwarding (CEF) and Inter Process-Communication (IPC) are explained on Cisco.com in the Troubleshooting CEF-Related Error Messages publication.
Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later
Note Output from this procedure will vary slightly depending on which line card you are using, but the basic information will be the same.
Line card field diagnostic software is designed to identify any faulty line card within a Cisco 12000 Series Router. Before Cisco IOS Software Release 12.0(22)S, the field diagnostic software was imbedded within the Cisco IOS software. Starting with Cisco IOS Software Release 12.0(22)S, this software is unbundled from the main image and must be downloaded from Cisco.com using the IOS Upgrade Planner.
Cisco initiated this change to accommodate users with 20-MB Flash memory cards. Field diagnostics are now stored and maintained as a separate image under the following name:
c12k-fdiagsbflc-mz-xxx-xx.s (where xxx-xx is the version number)
This image must be available on a separate Flash memory card, Flash disk, or TFTP boot server in order to load line card field diagnostics. The latest version is always available on Cisco.com. RP and fabric tests remain embedded within the main Cisco IOS software image.
While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing (5 to 20 minutes depending upon the complexity of the line card). Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems. The output of the diagnostic test without the verbose command appears like the following example:

If the line card fails the test, it will not reload automatically. You can manually reload the line card by using the hw-module slot slot reload command.
Field diagnostic results are stored in an electrically erasable programmable read-only memory (EEPROM) on the line card. It is possible to view the results of the last diagnostic test performed on the line card by executing the diag slot previous command.
There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty. As a precaution, if the line card fails and had been replaced previously, you should review this output with the Cisco TAC.
Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S
Note Output from this procedure will vary slightly depending on which line card you are using, but the basic information will be the same.
Line card field diagnostic software is bundled with the main Cisco IOS software to enable you to test whether a suspect line card is faulty. To use this feature, you must be in privileged enable mode, and issue the diag slot [verbose] command.
While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing. Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems.

Line Card Memory
This section contains information about the following:
•Removing and Installing Line Card Memory
You can replace the route memory on POS line cards. Route memory modules are installed into 144-pin small-outline DIMM (SODIMM) sockets. Route memory runs the Cisco IOS software image and stores the updated network routing tables downloaded from the route processor.
Table 29 provides information about the various hardware engines available with the POS line cards. The engine determines where the memory is placed.
Caution The user serviceability of memory modules varies from line card to line card. Read this section carefully before attempting to remove or install any line card memory module.

Removing and Installing Line Card Memory
Before beginning the memory replacement procedures in this section, ensure that you have the proper tools and equipment at hand, and that you are using appropriate ESD-prevention equipment and techniques. When removing or installing memory, observe the guidelines in the following sections:
•Checking the Installation of Line Card Memory
Removing a DIMM
To remove a DIMM from a line card, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.
Step 3 Locate the DIMM sockets on the line card.
Note Some line cards use DIMM sockets equipped with dual release levers, as shown in Figure 53; other line cards use DIMM sockets equipped with a single release lever, as shown in Figure 54. Both DIMM sockets operate in the same general way.
Figure 53 DIMM Socket with Dual Release Levers
Figure 54 DIMM Socket with Single Release Lever
Step 4 Use the socket release levers to eject the DIMM.
•For a socket with dual release levers (see Figure 53), pull down both levers at the same time to eject the DIMM.
or
•For a socket with a single release lever (see Figure 54), pull the lever to eject the DIMM.
Caution Handle the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket.
Step 5 As one end of the DIMM is released, grasp the top corners of the DIMM with the thumb and forefinger of each hand and pull the DIMM completely out of its socket.
Step 6 Immediately place the DIMM in an antistatic bag to protect it from ESD damage.
Step 7 Repeat Step 4 through Step 6 for any remaining DIMMs that you want to remove.
Installing a DIMM
This section contains instructions for installing DIMM memory into a line card.
Note If you are upgrading packet memory, both DIMM sockets of a given pair (either the transmit buffer or the receive buffer) must be populated with a DIMM of the same type and size.
To install DIMMs in a line card, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.
Caution To prevent router and memory problems, all DIMMs installed in the line card must be 3.3V devices.
Step 3 Remove the new DIMM from its protective antistatic bag.
Step 4 Grasp the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket. (See Figure 55.)
Step 5 To position the DIMM for insertion, orient it at the same angle as the DIMM socket. The two notches (keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in the socket. (See Figure 55.)
If necessary, rock the DIMM back and forth gently to align it in the socket.
Figure 55 Handling a DIMM
Caution When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If you damage a DIMM socket, you must return the line card for repair.
Step 6 Gently insert the DIMM into the socket and push until the DIMM snaps into place and the release lever is flush against the side of the socket.
Step 7 Verify that the release lever is flush against the side of the socket. If it is not, the DIMM might not be seated properly. On a socket with dual release levers, both levers should be flush against the sides of the DIMM.
If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the DIMM socket.
Step 8 Repeat Step 3 through Step 7 to install any remaining DIMMs for your memory configuration.
Removing a SODIMM
To remove a SODIMM, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.
Step 3 Locate the route memory socket on the line card.
Step 4 If present, remove the SODIMM retaining clip from the memory module socket. Grasp the latch arm intersection located on each side of the clip and gently slide the clip out. (See Figure 56.) Save the retaining clip.
Note Some line cards do not require a retaining clip.
Caution If the retaining clip is bent or damaged, do not attempt to fix or reuse it. This can cause serious damage to the line card. Each SODIMM replacement ships with a spare retaining clip, in case there is any damage to the existing clip.
Figure 56 Remove Retaining Clip from Memory Module Socket
Step 5 Remove the SODIMM by gently moving the plastic latches in an outward direction, parallel to and away from the memory module, until it releases and rotates to a 45-degree angle. (See Figure 57 and Figure 58a.)
Caution The plastic latch on the SODIMM socket is enclosed by the metal strain-relief latch. The plastic latch should never be moved past the metal strain-relief latch.
Caution Handle the edges of the SODIMM only. Do not touch the integrated circuit devices on the SODIMM, the metal traces, or fingers, along the edge of the SODIMM, or the pins in the SODIMM socket.
Figure 57 Moving the Plastic Latch Away from the SODIMM
Step 6 As the SODIMM is released, it positions itself at a 45-degree angle. Gently pull the SODIMM module out of the socket. Continue to keep the module at a 45-degree angle until it is completely removed from the socket guides. (See Figure 58b.)
Figure 58 Removing a 144-pin SODIMM Module
Step 7 Immediately place the SODIMM in an antistatic bag to protect it from ESD damage.
Installing a SODIMM
To install a SODIMM module, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.
Step 3 If there is a retaining clip, check to make sure that it has not been damaged or bent. (See Figure 59.)
Note Some line cards do not require a retaining clip.
Figure 59 SODIMM Socket Retaining Clip
Caution If the retaining clip is damaged, do not use it. This can damage the SODIMM socket.
Step 4 Locate the route memory socket on the line card.
Step 5 Remove the new SODIMM from its protective antistatic bag.
Caution Grasp the edges of the SODIMM only. Do not touch the integrated circuit devices on the SODIMM, the metal traces, or fingers, along the edge of the SODIMM, or the pins in the SODIMM socket.
Step 6 Line up the SODIMM key with the key in the board socket. (See Figure 60.)
Figure 60 SODIMM with Key in Face-Up Position
Step 7 The SODIMM must be lined up at a 45-degree angle. (See Figure 61a.)
Note When the key is in the face-up position, the metal traces on the left side of the key measure 0.9 inch (23.20 mm). The metal traces on the right side of the key measure 1.29 inches (32.80 mm). The SODIMM can not be inserted until the keys are lined up properly.
Step 8 Place both thumbs at the end of the socket and use your index fingers to guide the module into the socket until it is fully seated.
Be sure your index fingers are located on the outer corners of the SODIMM to maintain even pressure when the module is being seated in the socket.
Figure 61 Inserting a 144-pin SODIMM Module
Step 9 Gently press the SODIMM down using your index fingers, distributing even pressure across the module until it locks into the tabs. (See Figure 61b.)
Caution Excessive pressure can damage a SODIMM socket.
Step 10 Verify that the release levers are flush against the side of the socket. If they are not, the SODIMM might not be seated properly.
Step 11 If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the SODIMM socket.
Step 12 If there is a retaining clip, insert it by sliding the clip between the metal strain relief and the plastic latch.
(See Figure 62.)Figure 62 Inserting the Retaining Clip
The clip is properly installed when the clip detente protrudes below the strain relief and plastic latch. (See Figure 63.)

Checking the Installation of Line Card Memory
After you install line card memory and reinstall the line card in the router, the router reinitializes the line card and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations.
If the line card does not reinitialize properly after you upgrade memory, or if the console terminal displays a checksum or memory error, verify that you installed the correct SODIMMs and that they are installed correctly on the line card.
To check the installation of line card memory, follow these steps:
Step 1 Check that the SODIMM is fully inserted into the socket.
Step 2 Reinstall the line card and perform another installation check.
If the router fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, however, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem.

FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
Modifying the equipment without Cisco's authorization may result in the equipment no longer complying with FCC requirements for Class A digital devices. In that event, your right to use the equipment may be limited by FCC regulation and you may be required to correct any interference to radio or television communication at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
•Turn the television or radio antenna until the interference stops.
•Move the equipment to one side or the other of the television or radio.
•Move the equipment farther away from the television or radio.
