Installation preparation is presented in the following sections:
•Preventing Electrostatic Discharge
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.
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 DPT 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 DPT 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 DPT 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.
You need the following tools and parts to remove and install DPT line cards:
•Flat-blade or Phillips screwdriver
•ESD-preventive wrist or ankle strap and instructions
•Interface cables to connect the DPT line card with another router or switch
Note See the "Line Card Interface Cables" section for information on interface cables.
The following sections describe the procedures for removing and installing line cards:
•Guidelines for Line Card Removal and Installation
•Removing Mated DPT Line Cards
•Installing and Mating Two DPT Line Cards
Note Some of 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 Cisco 12000 Series Internet Routers differ, the designated use of slots and the process of installing and removing a line card are basically the same. Therefore, separate procedures and illustrations are not included in this publication.
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.
•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.
Note When working with mated DPT line cards, Cisco recommends that you use the shutdown command before removing the line cards from the router.
For line card configuration information, see the "Configuring and Troubleshooting Interfaces" section.
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 7 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 7a.)
Figure 7 Line Card Removal and Installation
Step 5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane connector. (See Figure 7b.)
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 7c.) 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 (VSR) line cards.
Warning Class 1M laser radiation when open. Do not view directly with optical instruments.
Note For information on disconnecting interface cables, see the "Removing and Installing Interface Cables" section.
For information on removing the cable-management bracket, see the "Removing a Line Card Cable-Management Bracket" section.
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.
Note In Cisco 12008 and Cisco 12012 Routers, the <wide line card> uses a pair of line card slots. You must install the blank filler into the rightmost slot of the pair before you can install the <wide 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.
Note If you are installing a <wide line card> into a Cisco 12008 or Cisco 12012 Router, you must install the line card into the slot to the left of the blank filler.
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 8.)
Figure 8 Ejector Levers
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.
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.
Note 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.
Note This section only applies to the 1-Port OC-48c/STM-16c and the 1-Port OC-192c/STM-64c DPT line cards.
The DPT line card in the lower-numbered slot is referred to as the first card in the pair and is represents side A of the DPT node. The second DPT line card in the higher-numbered slot is represents side B of the DPT node.
To remove only one DPT line card from a pair of mated DPT line cards connected with a mate cable, follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2 Remove the fiber cables from the transmit(TX) and receive(RX) ports before removing the mate cable.
Step 3 Use the hw-module slot number shutdown configuration command in Global Configuration mode to shut down the line card to be removed.
Step 4 Remove the mate cable completely from the line card to be removed. See the "Removing and Installing the Mate Cable" section.
Step 5 Remove the DPT line card following the steps in the "Removing a Line Card" section.
Step 6 Review the steps in the "Installing a Line Card" section for general line card installation information.
Step 7 Insert the new line card into the slot where the line card was removed.
Step 8 Connect the mate cable to new line card. See the "Removing and Installing the Mate Cable" section.
Step 9 Use the no hw-module slot number shutdown configuration command in Global configuration mode to activate the newly-added line card.
Step 10 Use the hw-module slot number srp configuration command to enable the SRP interface, where number is the leftmost (or topmost if horizontal) slot of the pair of slots occupied by the two line cards. This command prevents any anomalies to the running configuration if you mistakenly install a DPT line card into the second slot first.
Step 11 Connect the fiber cables to the transmit(TX) and receive(RX) ports of the newly-added line card.
Note This section only applies to the 1-Port OC-48c/STM-16c and the 1-Port OC-192c/STM-64c DPT line cards.
Note Cisco strongly recommends that you use the shutdown command prior to removing mated 1-Port OC-48c/STM-16c or mated 1-Port OC-192c/STM-64c DPT line cards to prevent anomalies when you reinstall two new or reconfigured DPT line cards. When you shut down an SRP interface, it is designated as administratively down in the show command display.
To remove two DPT line cards connected with a mate cable, follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2 Remove the fiber cables from the transmit (TX) and receive (RX) ports before removing the mate cable.
Step 3 Remove the mate cable completely from both line cards. See the "Removing and Installing the Mate Cable" section.
Step 4 Remove each DPT line card following the steps in the "Removing a Line Card" section.
Note When you remove both sides of the mate cable, the line card automatically enters wrap mode on the remaining line card and creates half of an SRP ring. (See Figure 34.)
Note This section only applies to the 1-Port OC-48c/STM-16c and the 1-Port OC-192c/STM-64c DPT line cards.
You can install two DPT line cards in any two adjacent line card slots not occupied by other system cards such as the RP. If you install a new line card, you must first remove the line card blank from the available slot. See the procedures in the "Removing a Line Card" section.
When you first install a pair of DPT line cards, ensure that the first DPT line card is inserted into the lower (or topmost) slot number first. The DPT line card in the lower-numbered slot is referred to as the first card in the pair and is represents side A of the DPT node. The second DPT line card in the higher-numbered slot is represents side B of the DPT node.
For example, assume that a pair of 1-Port OC-48c/STM-16c DPT line cards are present in slots 4 and 5. The line card in slot 4 is the first card of the pair of 1-Port OC-48c/STM-16c DPT line cards (side A), and the line card in slot 5 is the second card (side B).
When two DPT line cards are connected by a mate cable, they behave as one interface, share one IP address, and are referenced via the line card in the first slot. You must enter the hw-module slot number srp configuration command on the first line card to enable the paired line cards.
Follow these steps to install two 1-port DPT line cards into adjacent slots in a Cisco 12000 Series Internet Router:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2 Review the steps in the "Installing a Line Card" section for general line card installation information.
Step 3 Insert the first line card into the leftmost (or topmost if horizontal) slot. There is a slight delay while the line card initializes.
Step 4 Insert the second line card into the adjacent slot. There is a slight delay while the line card initializes.
Step 5 Connect the mate cable to each DPT line card. See the "Removing and Installing the Mate Cable" section.
Step 6 Use the hw-module slot number srp configuration command to enable the SRP interface, where number is the leftmost (or topmost if horizontal) slot of the pair of slots occupied by the two line cards. This command prevents any anomalies to the running configuration if you mistakenly install a DPT line card into the second slot first.
Step 7 Install the line card cable-management bracket. See the "Installing a Line Card Cable-Management Bracket" section.
Step 8 Install the interface cables. See the "Removing and Installing Interface Cables" section.
Before you remove or install an SFP module, read the installation information in this section. Before servicing an SFP module, see the " Laser Safety" section.
DPT 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.
Note Only the 4-Port OC-48c/STM-16c line card uses SFP modules.
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:
The bale clasp SFP module has a clasp that you use to remove or install the SFP module. (See Figure 9.)

Cisco 12000 Series Internet 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.
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 Internet 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 22 shows the single-port line card cable-management bracket; Figure 23 shows the multiport line card cable-management bracket.
Figure 22 Single-Port Line Card Cable-Management Bracket
Figure 23 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.
Removing and installing the line card cable-management bracket is described in the following procedures:
•Removing a Line Card Cable-Management Bracket
•Installing a Line Card Cable-Management Bracket
To remove a line card cable-management bracket, follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2 Note the current interface cable connections to the ports on each line card.
Step 3 Starting with the interface cable for the bottom port on the line card, disconnect the cable from the line card interface.

Note For information on disconnecting and connecting interface cables, see the "Removing and Installing Interface Cables" section.
The following sections provide specifications for DPT line cards:
•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 (see Table 14), you should use an optical time domain reflectometer (OTDR) to measure the power loss. All DPT line cards meet both the EN60825\IEC60825 and FDA - Code of Federal Regulations (USA) laser safety standards.
The following sections describe the power budget and signal specifications for the optics used in each DPT line card:
•1-Port OC-12c/STM-4c DPT Line Card Power Specifications
•4-Port OC-12c/STM-4c ISE DPT Line Card Power Specifications
•1-Port OC-48c/STM-16c DPT Line Card Power Specifications
•4-Port OC-48c/STM-16c DPT Line Card Power Specifications
•1-Port OC-192c/STM-64c DPT Line Card Power Specifications
The 1-Port OC-12c/STM-4c DPT line card provides one full-duplex, 622-Mbps, laser-based, SONET/SDH-compliant interface. Table 10 lists the power ratings and distances of each 1-Port OC-12c/STM-4c DPT line card. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.

The 4-Port OC-12c/STM-4c ISE DPT line card provides four full-duplex, 622-Mbps, laser-based, SONET/SDH-compliant interfaces. Table 11 lists the power ratings and distances of each 4-Port OC-12c/STM-4c ISE DPT line card. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.
The 1-Port OC-48c/STM-16c DPT line card provides a full-duplex, 10-Gbps, laser-based, SONET/SDH- compliant interface. Table 12 lists the power budget and signal specifications of each 1-Port OC-48c/STM-16c DPT line card. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.
The 4-Port OC-48c/STM-16c DPT line card uses SFP modules that support single-mode operation only. All SFP modules provide a full-duplex, 10-Gbps, laser-based SONET/SDH-compliant interface. Table 13 lists the power ratings and distances of each SFP module. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.
Note Only use SFP modules supplied by Cisco. 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 4-Port OC-48c/STM-16c DPT line cards. Unapproved SFP modules (those not purchased directly from Cisco) will not work.
The 1-Port OC-192c/STM-64c DPT line card provides a full-duplex, 10-Gbps, laser-based, SONET/SDH-compliant interface. Table 14 lists the power budget and signal specifications of each 1-Port OC-192c/STM-64c DPT line card. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.

1 Runs on multimode fiber only |
The following types of cables are used with DPT 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 DPT line cards:
•Subscriber connector (SC)—See Figure 26
•Lucent connector (LC)— See Figure 27
•Multiple terminations push-pull latch (MTP)—See Figure 28

Attach one simplex fiber cable between the line card and the device to which the line card is connected. Observe the receive (RX) and transmit (TX) cable relationship shown in Figure 29.
Note Duplex fiber cables are also supported.
Table 15 lists the cable and connector types for all DPT line cards.
To remove an interface cable, follow these steps:
Step 1 Attach an ESD-preventive wrist 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 26, Figure 28, or Figure 27.)
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.
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 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 29.

Step 4 Insert the connector until it clicks and locks into place.
Step 5 Attach the other end of the cable to another node in the SRP ring. The TX side A port on the line card must be connected to the RX side B port on the next node, and the RX side A port on the line card must be connected to the TX side B port on the next node. The labels next to the fiber connectors identify side A TX and RX, and side B TX and RX.
Step 6 Repeat these steps until all nodes are connected.
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.
As an example, Figure 30 illustrates the connections necessary to create a four-node DPT ring.
Figure 30 Creating a DPT Ring Using DPT Line Cards
Use Table 16 and Figure 31 to help organize the cable connections for a four-node DPT ring.
Figure 31 Topology of Four-Node DPT Ring
Table 17 lists the required specifications for VSR cables.
Note You must use multimode fiber cables with fiber ribbon that meets these specifications.
Note This section only applies to the 1-Port OC-48c/STM-16c and 1-Port OC-192c/STM-64c DPT line cards.
Each 1-Port OC-48c/STM-16c and 1-Port OC-192c/STM-64c DPT line card is equipped with a front-panel connector labeled Mate. This connector is used with a copper coaxial cable that mates two 1-Port OC-48c/STM-16c or two 1-Port OC-192c/STM-64c DPT line cards. The copper coaxial cable is referred to as a mate cable. A mate cable is included in your line card product package.
Note Do not attempt to mate a 1-Port OC-48c/STM-16c DPT line card to a 1-Port OC-192c/STM-64c DPT line card. This configuration is not supported. You must mate two line cards of the same type.
The mate cable (Part Numbers CBL-SRP-OC48 and CBL-SRP-OC192) allows mated 1-Port OC-48c/STM-16c or mated 1-Port OC-192c/STM-64c DPT line cards to do the following:
•Share one IP address and MAC address
•Facilitate data traffic pass-through between two DPT line cards
•Synchronize the Ring Access Controller application-specific integrated circuits (RAC ASICs) on both line cards
•Create a two-fiber SRP ring
Note The procedures in the following sections use illustrations of a 1-Port OC-192c/STM-64c DPT line card to support the descriptions of removing and installing the mate cable. Although the mate cables of the 1-Port OC-48c/STM-16c and the 1-Port OC-192c/STM-64c DPT line cards differ, the use of the mate cable and the process of installing and removing a mate cable are basically the same. Therefore, separate procedures and illustrations are not included in this publication.
To remove the mate cable, follow these steps:
Step 1 Press on the push-button latches on the sides of the connector.
Step 2 Gently pull the connector from the port on each line card until the connector is fully removed from each port.
To install a mate cable, follow these steps:
Step 1 Use two hands to bend the straight mate cable into a U-shape. (See Figure 32.)
Figure 32 Bending and Handling the Mate Cable
Figure 33 2 DPT Line Cards with Mate Cable (OC-192c/STM-64c Shown)
Step 2 Use the push-buttons on the sides of the cable connector to connect it to the line cards. (See Figure 33.)
Each mated DPT line card is hot swappable and provides redundancy that allows you to remove one line card while your router retains presence on the SRP ring with the second line card, which remains installed in the chassis.
Note Although mated DPT line cards are slot independent, the adjacent router slot must always be available for a second DPT line card so that you can create a two-fiber ring.
When two DPT line cards are mated and the RACs are synchronized, they create a two-fiber ring without any wraps. When the RACs on the DPT line cards are unsynchronized, they automatically create a two-fiber ring that is in wrapped mode.
Figure 34 shows synchronized and unsynchronized conditions on an SRP ring.
The LEDs on the DPT line card indicate the conditions on the SRP ring. See the "Status LEDs" section for details. To synchronize mated DPT line cards, see the "Configuring a Mated Line Card Interface" section.
Note If the Wrap LED on the line card goes on due to an unsynchronized signal fail, reseat or replace the mate cable.
When the line cards are not connected by the mate cable, each DPT line card is the equivalent of a single-fiber SRP ring on side B. The single-fiber SRP ring has a wrap at each end to ensure that all data packets will reach their destination. (See Figure 35.)
Figure 34 DPT Line Cards with Mate Cable (OC-192c/STM-64c Shown)
Figure 35 DPT Line Card as a Single-fiber SRP Ring (OC-192c/STM-64c Shown)
The following sections describe how to verify and troubleshoot line card installation:
•Troubleshooting the Installation
During a typical line card boot process, the following events occur:
1. The line card maintenence 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 itself to accept its Cisco IOS software load 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 display 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 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 "Configuring and Troubleshooting Interfaces" section to identify any possible problems.
After installing the line card and connecting the interface cables, verify that the line card is working properly by checking the following LEDs on the faceplate:
•Interface status LEDs show the status of each fiber-optic connector. DPT line cards can contain some or all of the following status LEDs (see Figure 1, Figure 2, Figure 3, Figure 4 and Figure 6 for your particular model):
–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 SRP packet reception on this port
–Synch—Indicates the status of the ring access controllers (RACs) on mated 1-Port OC-48c/STM-16c DPT line cards
–Wrap—Indicates the status of wrap conditions on this port
–Pass Through or Pass Thru—Indicates if traffic is passing through the node transparently or normally
•Alphanumeric LEDs. Two four-digit alphanumeric LEDs display messages that explain the state of the line card. (See the "Alphanumeric LEDs" section.)
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 Interfaces" section.)
The following sections describe status LED information for each DPT line card:
•1-Port OC-12c/STM-4c DPT Line Card LEDs
•4-Port OC-12c/STM-4c ISE DPT Line Card LEDs
•1-Port OC-48c/STM-16c DPT Line Card LEDs
•4-Port OC-48c/STM-16c DPT Line Card LEDs
•1-Port OC-192c/STM-64c DPT Line Card LEDs
See Figure 1 for the location of the LEDs on the 1-Port OC-12c/STM-4c DPT line card. The different operating states of the status LEDs are shown in Table 18.

DPT 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 23.
Note It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in Table 23 and Table 24 may not appear on your line card.

If the 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, you should verify that the interface is not shut down. If 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 you are installing two mated DPT line cards, use the show running configuration EXEC command to determine if the SRP interface is administratively down. If the SRP interface is disabled, enter the hw-module slot number srp configuration command to enable the SRP interface. The problem may have occurred if you installed line cards in reversed order.
Step 4 If the Active LED still fails to go on, remove the DPT 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 5 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 Internet Router.
This section provides procedures and configuration examples to configure your DPT line card (s). A command line interface (CLI) is provided to configure and display parameters for both the DPT and the SONET/SDH framer. It also contains troubleshooting information.
This section contains the following procedures:
•Configuring a Mated Line Card Interface
•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
Note This section only applies to the 1-Port OC-48c/STM-16c and the 1-Port OC-192c/STM-64c DPT line cards.
When two 1-Port OC-48c/STM-16c or two 1-Port OC-192c/STM-64c DPT line cards are connected by a mate cable, they behave as one SRP interface and share one IP address. Once configured, you will access the DPT interface created using the two cards through the line card that acts as Side A of the DPT node.
Note Side A is automatically the leftmost (or topmost if horizontal) slot of the pair of mated DPT line cards.
A Cisco 12000 Series Internet Router identifies an SRP interface address by its line card slot number and port number, in the format slot/port. For example, the slot/port address of an SRP interface on a 1-Port OC-48c/STM-16c DPT line card installed in line card slot 4 and port 0 is 4/0. In the case of mated DPT line cards, you will access only the line card in the first slot of the pair of slots.
To initially configure two mated DPT line cards in, for example, slot 4 and slot 5 of a Cisco 12000 Series Internet Router, follow these steps:
Step 1 Use the enable command to enter the privileged EXEC command mode. The system will prompt you for a password if one is set.
Router> enable
Step 2 Enter the show running configuration command to verify that both line cards are shut down.
Router# show running configuration
.......
hw-module slot 4 shutdown
hw-module slot 5 shutdown
Step 3 Enter the configure terminal command to enter configuration mode.
Router# configure terminal
Step 4 Enter the hw-module slot srp configuration command to bring up the line cards.
Router (config)# hw-module slot 4 srp
Router (config)# end
where slot is the slot number of the leftmost line card, or side A.
Step 5 Write the new configuration to nonvolatile random access memory (NVRAM) by using the copy running-config startup-config command:
Router# copy running-config startup-config
[OK]
Step 6 Use the show gsr command to monitor stages of the IOS download to the line cards.
When the Cisco IOS software is successfully downloaded, the LED status should be "IOS RUN."
After you verify that a new line card is installed correctly (the Active LED goes on), you must enter the privileged EXEC command mode by using the enable command. The system will prompt you for a password if one is set. Use the configure command to configure the new interface.
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 an 1-Port OC-48c/STM-16c DPT line card installed in line card slot 2 and chassis port 0 is 2/0. Even though the card contains only one port, you must use the slot/port notation.
Use the configure terminal command to enter the configuration mode if you want to change the default configuration values on the line card. Be prepared with the information you will need, such as the IP address. (See Table 25.)

To configure a DPT line card, follow these steps:
Step 1 Confirm that the system recognizes the card by entering the show version command.
Router# show version
Step 2 Check the status of each port by entering the show interface srp slot/port command.
Router# show interface srp 2/0
Step 3 Enter configuration mode and specify that the console terminal will be the source of the configuration commands.
Router# configure terminal
Step 4 Enable IP routing by entering the ip routing command.
Router(config)# ip routing
Step 5 For the 4-Port OC-12c/STM-4c ISE DPT line card, you can enable high-speed IP multicast packet forwarding on the hardware engine of the line card by using the hw-module slot ip multicast hw-accelerate command:
Router(config)# hw-module slot 2 ip multicast hw-accelerate
Step 6 At the prompt, specify the new interface to configure by entering the interface command, followed by the type (srp) and slot/port (line card slot number/port number). The example that follows is for a 1-Port OC-48c/STM-16c DPT line card in chassis slot 2, port 0.
Router(config)# interface srp 2/0
Step 7 Assign an IP address and subnet mask to the interface with the ip address configuration command.
Router(config-if)# ip address 10.0.0.1 255.255.255.0
Step 8 Verify that the default value for the clock source is correct.
The default setting is srp clock source internal. Typically, when two Cisco 12000 Series Routers are connected back to back, or are connected over dark fiber, where no external clocking is available, set the clock source on each device to internal (default). If a router is connected to a SONET/SDH Add/Drop Multiplexer (ADM), configure the clock-source for srp clock source line on the side that is actually connected to the ADM.
Note The only time both sides A and B should be set to source line is when both sides are connected to different ADM systems.
Router(config-if)# srp clock-source line a
Router(config-if)# srp clock-source line b
Step 9 Change the shutdown state to up and enable the interface.
Router(config-if)# no shutdown
The no shutdown command passes an enable command to the line card. It also causes the line card to configure itself automatically, based on the previous configuration commands sent.
Note The line card cable is connected to both a Cisco 12000 Series Router device and a high-end router or switch. Step 10 to Step 12 apply to both the Cisco 12000 Series Router device and the other device.
Step 10 SONET is the default framing type. If you are connected to an SDH network, you need to change the framing type by entering the srp framing interface configuration command.
Router1(config-if)# srp framing sdh [a|b]
Step 11 Add any other configuration commands required to enable routing protocols and adjust the interface characteristics.
Step 12 When you have included all the configuration commands to complete the configuration, enter Ctrl-Z (press the Control key while you press Z) to exit configuration mode.
Step 13 Write the new configuration to memory.
Router1# copy running-config startup-config
The system displays an OK message when the configuration has been stored.
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.
The following are examples of system output that you may see if your Cisco 12000 Series Internet Router line card fails. Key data in the output is underlined.

The type of failure that has occurred in the show context slot 2 example is identified by the underlined SIG= value. 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).
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.
Router# show led
SLOT 1 : RUN IOS
SLOT 6 : DNLD FABL
SLOT 7 : RP ACTV
SLOT 10 : RUN IOS
SLOT 11 : RUN IOS
SLOT 13 : RUN IOS
SLOT 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 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 crashed
You 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.
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.
If the line card does not boot and you receive an error message indicating that there is a problem with the Field-Programmable Gate Array (FPGA) image (or if the line card alphanumeric LED display remains frozen in IOS STRT state), you need to upgrade the FPGA image using the update-fpga option in the diag command.
Note The diag command and the update-fpga option are documented in the Field Diagnostics for the Cisco 12000 Series Internet Router publication.
When the Cisco IOS image boots, it verifies that a compatible FPGA image is running on the router. The major version number of the FPGA image must be the same as that expected by the Cisco IOS image; the minor version number on the FPGA image must be the same or greater than the minor version number expected by the Cisco IOS image. For example, if the Cisco IOS image expects a minimum FPGA image of 03.02, the software will verify that the actual major version number of the FPGA image in the line card bootflash is 03, and that the minor version number is 02 or above.
Example error messages indicating an FPGA problem appear as follows:
Error Message No FPGA image available for slot0. Please run field diagnostics image on slot0 to upgrade the FPGA image.
Explanation There is currently no valid FPGA image in the bootflash of the line card. You must load a valid FPGA image to the line card bootflash.
Error Message FPGA image not appropriate or corrupted for slot0. Please run field diagnostics on slot0 to upgrade the FPGA image.
Explanation The FPGA image currently loaded in the line card bootflash is not compatible with the Cisco IOS software release currently running on the router or is corrupted. Upgrade the FPGA image to the correct version.
Note Do not confuse the line card bootflash with the route processor (RP) bootflash. FPGA images are loaded only to the line card bootflash.
Note FPGA error messages are only applicable to 4-Port OC-12c/STM-4c ISE DPT line cards.
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 Internet 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:
Router# diag 7 tftp://223.255.254.254/diagnostic/award/c12k.fdiagsbflc.mz.120-25.s

The line card reloads automatically only after passing the test. 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 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.

DPT line cards include the following types of memory:
•Route memory
•Packet memory
•Pointer look-up (PLU) memory (not user serviceable)
•Table look-up (TLU) memory (not user serviceable)
Line card memory configurations and memory socket locations differ, depending on the line card engine type. Table 26 lists the DPT line card engine types:

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. Before removing or installing memory, observe the following guidelines:
•Route memory DIMMs (1-Port OC-12c/STM-4c and 1-Port OC-48c/STM-16c line cards only)
–Route memory DIMM0 socket must always be populated.
–For certain memory configurations, the route memory DIMM1 socket can remain empty.
–DIMMs must be 3.3V devices.
•Packet memory DIMMs (1-Port OC-12c/STM-4c and 1-Port OC-48c/STM-16c line cards only)
–All four DIMM sockets for SDRAM buffer memory must be populated.
–Both DIMM sockets for a given buffer pair (either those for the transmit buffer or those for the receive buffer) must be populated with SDRAM DIMMs of the same type and size.
–Size of the DIMMs in the transmit buffer need not match the size of the SDRAM DIMMs in the receive buffer.
–DIMMs must be 3.3V devices.
This section contains the following procedures:
•Checking the Installation of Line Card Memory
Refer to Figure 36, Figure 37, Figure 38 and Figure 39 for the location of the memory on your line card.
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 40; other line cards use DIMM sockets equipped with a single release lever, as shown in Figure 41. Both DIMM sockets operate in the same general way.
Figure 40 DIMM Socket with Dual Release Levers
Figure 41 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 40), pull down both levers at the same time to eject the DIMM.
or
•For a socket with a single release lever (see Figure 41), pull the lever to eject the DIMM.
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.
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.
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 42.)
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 42.)
If necessary, rock the DIMM back and forth gently to align it in the socket.
Figure 42 Handling a DIMM
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.
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 43.) Save the retaining clip.
Note Some line cards do not require a retaining clip.
Figure 43 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 44 and Figure 45a.)
Figure 44 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 45b.)
Figure 45 Removing a 144-pin SODIMM Module
Step 7 Immediately place the SODIMM in an antistatic bag to protect it from ESD damage.
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 46.)
Note Some line cards do not require a retaining clip.
Figure 46 SODIMM Socket Retaining Clip
Step 4 Locate the route memory socket on the line card.
Step 5 Remove the new SODIMM from its protective antistatic bag.
Step 6 Line up the SODIMM key with the key in the board socket. (See Figure 47.)
Figure 47 SODIMM with Key in Face-Up Position
Step 7 The SODIMM must be lined up at a 45-degree angle. (See Figure 48a.)
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 48 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 48b.)
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 49.)
Figure 49 Inserting the Retaining Clip
The clip is properly installed when the clip detente protrudes below the strain relief and plastic latch. (See Figure 50.)
Figure 50 Retaining Clip Completely Installed into Module Latch
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 DIMMs and that they are installed correctly on the line card.
To check the installation of line card memory, follow these steps:
Step 1 Check the packet memory DIMMs to verify that both DIMMs are the same type, size, and speed. DIMMs must operate at 60 ns or faster. The speed of the DIMM is printed along one of its edges.
Step 2 Check the alignment of the DIMMs by looking at them across the horizontal plane of the card. The DIMMs should be aligned at the same angle and be fully inserted into their respective sockets. If a DIMM is not correctly aligned, remove it and reinsert it.
Step 3 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.
