Physical Layer Interface Modules

A physical layer interface module (PLIM) provides the packet interfaces for the routing system. Optic modules on the PLIM contain ports to which fiber-optic cables are connected. User data is received and transmitted through the PLIM ports and converted between the optical signals (used in the network) and the electrical signals (used by Cisco CRS-1 router components).

Each PLIM is paired with a modular services card (MSC) through the chassis midplane. The MSC provides Layer 3 services for the user data, and the PLIM provides Layer 1 and Layer 2 services. An MSC can be paired with different PLIMs to provide a variety of packet interfaces and port densities (for example, OC-192c/STM-64c POS and 10-Gigabit Ethernet).

MSCs and PLIMs are installed on opposite sides of the line card chassis and mate through the chassis midplane. Each MSC and PLIM pair is installed in corresponding chassis slots in the chassis (on opposite sides of the chassis). The chassis midplane enables you to remove and replace an MSC without disconnecting the user cables on the PLIM.

The Cisco CRS-1 router supports the following number of PLIMs for each chassis type. You can mix and match PLIM types in the chassis.

The 16-slot chassis supports from 1 to 16 PLIMs.

The 8-slot chassis supports from 1 to 8 PLIMs.

For additional information about the operation of MSCs and PLIMs, see Cisco CRS-1 Carrier Routing System Line Card Chassis System Description for the 16-slot or 8-slot chassis.

Figure 6 PLIM Impedance Carrier

Before You Remove or Install a PLIM or an SFP Module

Review the following sections carefully before you remove or install a PLIM or an SFP module:

Safety Guidelines

Preventing Electrostatic Discharge

Guidelines for Card Installation and Removal

Safety Guidelines

Before you perform any procedure in this document, 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 Regulatory Compliance and Safety Information for the Cisco CRS-1 Carrier Routing System before installing, configuring, or troubleshooting any installed card.


Never attempt to lift an object that might be too heavy for you to lift by yourself.

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.

Keep tools and router components away from walk areas.

Do not wear loose clothing, jewelry, and other items that could get caught in the router while working with OIMs, SFCs, and their associated components.

Use Cisco equipment in accordance with its specifications and product-usage instructions.

Do not work alone if potentially hazardous conditions exist.

Make sure your installation follows national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 60364, part 1 through part 7.

Connect only a DC power source that follows the safety extra-low voltage (SELV) requirements in UL/CSA/IEC/EN 60950-1 and AS/NZS 60590 to the FCC DC-input power system.

Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed wiring of an LCC configured with the DC-input power system.

The LCC requires short-circuit (overcurrent) protection to be provided as part of the building installation.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend that you use an ESD-preventive strap whenever you handle network equipment or components.

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 a bare metal surface on the chassis.

Handle a card by its ejector levers, when applicable, or metal carrier only; avoid touching the board or connector pins.

Place a removed card component 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 card and clothing. The wrist strap protects the board only from ESD voltage on the body; ESD voltage on clothing can still cause damage.

Guidelines for Card Installation and Removal

Guidelines for card installation and removal include the following:

Online insertion and removal (OIR) is supported, enabling you to remove and install cards while the router is running. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation. Notifying the software or resetting the power is not required. However, you have the option of using the shutdown command before removing a card.


Note For PLIMs with DPT interfaces, we recommend that you use the srp ips request forced-switch command to minimize data loss. See Cisco IOS XR Interface and Hardware Component Configuration Guide for details.


Each PLIM and its corresponding MSC function as a pair. If either card is removed, the other card is essentially powered down (although the router can still identify and inventory the cards).

PLIMs in the line card chassis are attached to the chassis by way of a pair of ejector levers and captive screws. The two ejector levers are used to release the PLIM from its midplane connector. The ejector levers and captive screws are located on the upper and lower ends of the faceplate of the card (see Figure 7).

Figure 7 Ejector Levers and Captive Screws

1

Captive screw

2

Ejector lever



Caution When you remove a PLIM, always use the ejector levers to ensure that the connector pins disconnect from the midplane in the sequence expected by the router.

The router can indicate a hardware failure if you do not follow proper procedures. Remove or install only one card at a time. Wait at least 15 seconds before removing or installing another card.

How to Remove or Install a PLIM

A PLIM provides the data interfaces for the routing system and mates with its associated MSC through the chassis midplane.

This section contains the following procedures:

This section describes how to remove a PLIM from the line card chassis.


Caution The system may indicate a hardware failure if you do not follow proper procedures. Remove or install only one PLIM at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or installing another PLIM.

Required Tools and Equipment

You need the following tools to remove a PLIM:

ESD-preventive wrist strap

Medium Phillips screwdriver

Steps

To remove a PLIM, see Figure 8 and follow these steps (the 16-port OC-48c/STM-16c POS/DPT PLIM is shown in the illustration, but the installation procedure is similar for all PLIMs).


Step 1 Attach the ESD-preventive wrist strap and follow its instructions for use.

Step 2 Identify the card to be replaced, and unplug the interface cables connected to the card. Be sure to note the current connections of the cables to the ports on the PLIM.


Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Statement 125

Note You can also keep the dust caps or covers on the laser optical bores to avoid radiation exposure.


Step 3 (OC-48c/STM-16c POS/DPT PLIMs only) Remove the SFP modules from the card and set them aside. See the "How to Remove or Install an SFP Module" section.

Step 4 Loosen the two captive screws holding the card in place.

Step 5 Grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees (70 degrees for a newer PLIM) away from the front edge of the card carrier to unseat the card from the backplane.

Step 6 Grasp the cable management bracket and gently pull the PLIM halfway from the slot.

Step 7 Slide the card from the slot, using one hand under the PLIM to support and guide it. Avoid touching the PLIM printed circuit board, components, or any connector pins. Do not lift cards by the cable management bracket; lift them from the bottom, using the cable management bracket only as an aid for balance.

Step 8 Place the PLIM directly into an antistatic sack or other ESD-preventive container.

Step 9 Insert another PLIM or an impedance carrier into the empty card slot.

Installing a PLIM

This section describes how to install a PLIM in the line card chassis. You can install a PLIM in any slot not occupied by a route processor (RP) card (or a fan controller card, 16-slot chassis only). If you install a new MSC or PLIM, you must first remove the impedance carrier card from the available slot.


Caution The system can indicate a hardware failure if you do not follow proper procedures. Remove or install only one PLIM at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or installing another PLIM.

Required Tools and Equipment

You need the following tools and part to install a PLIM:

ESD-preventive wrist strap

Medium Phillips screwdriver

PLIM

Steps

To install a PLIM, see Figure 8 and follow these steps:


Step 1 Attach the ESD-preventive wrist strap and follow its instructions for use.

Step 2 Remove the PLIM from its antistatic packaging.

Step 3 Remove the PLIM impedance carrier from the slot you need to fill and set it aside.


Note Remove only one impedance carrier and install one PLIM at a time. Be sure to verify that each PLIM is fully installed and secured before installing another card.


Step 4 Grasp the cable management bracket with one hand and place your other hand under the carrier to support and guide the card into the correct slot. Slide the card halfway into the correct slot. Avoid touching the card circuitry or any connectors.

Step 5 Pivot both card ejector levers so that the openings on the card ejector cams at the top and bottom of the card pass over the tabs on each side of the card cage slot.


Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both ejector levers might bind when you attempt to close the ejector levers, thereby damaging or breaking one or both ejector levers.

Step 6 Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the tabs on each side of the card cage slot.


Note Guide pins exist that make initial contact with the backplane connector as you slide a card into its slot. After the guide pins make contact, continue pushing on the card carrier until the card ejector levers begin pivoting forward toward the handle in the card carrier.


Step 7 To seat the card in the midplane connector, grasp both card ejector levers and pivot them inward toward the handle in the card carrier until they are flush against the front edge of the card carrier.

Step 8 Engage both captive screws on the PLIM, and then tighten the screws.


Caution Be sure to engage both captive screws on the PLIM before you begin to tighten the screws; otherwise, the PLIM might not seat properly.

Caution To ensure adequate space for additional PLIMs, always tighten the captive installation screws on each newly installed PLIM before you insert another PLIM. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the system.

Step 9 (OC-48c/STM-16c POS/DPT PLIMs only) Install the SFP modules.

Step 10 Install the interface cables. We recommend that you clean the fiber-optic connections before attaching the cables. See the URL http://www.cisco.com/warp/public/127/cleanfiber2.html for cleaning instructions.

Step 11 If this PLIM is new, configure it for operation. For instructions, see Cisco IOS XR Interface and Hardware Component Configuration Guide and the Cisco IOS XR Interface and Hardware Component Command Reference, available at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/iosxr/index.htm

Note You can also keep the dust caps or covers on the laser optical bores to avoid radiation exposure.


How to Remove or Install an SFP Module

A small form-factor pluggable (SFP) module provides the optics ports for some types of PLIMs. An SFP module is installed into a port on the PLIM. The SFP module has a bale-clasp latch that you use to install or remove the module (see Figure 9).

Caution Protect the SFP module by inserting a clean dust cover into the module after you remove the fiber cable. Be sure to clean the optic surfaces of the fiber cable before you plug the cable into another module. Avoid getting dust and other contaminants in the optical port of the SFP module. The optics do not work correctly when obstructed with dust.


Note Only the 16-port OC-48c/STM-16c POS/DPT PLIM uses SFP modules.

Cleaning Optics

It is important to inspect and clean fiber-optic components before making a fiber-optic connection (for example, plugging a fiber-optic connector into a fiber-optic receptacle). Any contamination in the fiber connection can cause the optic component or the whole system to fail. Even microscopic dust particles, oil from human hands, film residues (condensed from vapors in the air), and powdery coatings (left after water or other solvents evaporate) can cause a variety of problems for optical connections.


Caution With the high-powered lasers now in use, any contaminant can be burned into the fiber end face if it blocks the core while the laser is turned on. This burning may damage the optical surface enough that it cannot be cleaned.

See the following URL for instructions on how to clean fiber-optic components:

http://www.cisco.com/warp/public/127/cleanfiber2.html

Always follow the fiber-optic cleaning procedures carefully. The goal is to eliminate any dust or contamination and provide a clean environment for the fiber-optic connection. Inspection, cleaning, and reinspection are critical steps that must be performed before making any fiber-optic connection.

How to Remove or Install a PLIM Cable Management Bracket

Cisco CRS-1 chassis 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:

The line card chassis arrives preinstalled with a horizontal cable management bracket on the front of the chassis and an optional horizontal cable management bracket available for the rear of the chassis. The cable management system organizes the interface cables entering and exiting the different cards, keeping them out of the way and free of sharp bends. See the appropriate Cisco CRS-1 installation guide for more information on the chassis cable management bracket.

A cable management bracket that attaches to a PLIM.

This section describes how to remove and install the PLIM cable management bracket. Figure 12 shows the PLIM cable management bracket.

Figure 12 PLIM Cable Management Bracket


Caution Do not use the cable management bracket alone as a handle to pull out or push in the PLIM. One hand must be under the PLIM to support its weight when carrying the PLIM. 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 PLIM after it is removed from the router.

Verifying the Installation of a PLIM

This section describes how to verify that the PLIM has been properly installed. See Figure 2, Figure 4, and Figure 5 for the location of the port and STATUS LEDs on the front panel of the POS and POS/DPT PLIMs.

Troubleshooting the PLIM

If a PLIM fails to operate or power up on installation:

Make sure that the PLIM is seated firmly in the line card chassis slot. One easy way to verify physical installation is to see whether the front faceplate of the PLIM is even with the fronts of the other PLIMs installed in the card cage.

Make sure that the corresponding MSC is installed and operating correctly.

Check whether the ejector levers are latched and that the captive screws are fastened properly. If you are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the PLIM.

Determine whether there are any active alarms by looking at the alarm LEDs on the alarm module (16-slot) or route processor (8-slot). See Cisco CRS-1 Carrier Routing System Line Card Chassis System Description for more information about alarms.

Examine the power shelves (16-slot chassis) or power distribution units (PDUs) (8-slot chassis) to see whether the chassis, as a whole, is receiving power.

Some PLIMs can operate in DPT mode (for example, the OC-192c/STM-64c POS/DPT PLIM). See the DPT LED descriptions in Table 10 to assist you with troubleshooting.

Use the LEDs on the PLIM to verify the correct installation and operation of the card. See "POS and DPT LED Descriptions" for more information.

POS and DPT LED Descriptions

The PLIM STATUS LED indicates the status of the PLIM. Port LEDs show the status of each fiber-optic connector. POS and DPT interfaces use the following port LEDs:

ACTIVE/FAILURE—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.

POS/DPT PLIMs use the following additional port LEDs:

WRAP—Indicates a wrap on a DPT ring.

PASS THRU—Indicates pass-through mode for DPT ports.

DPT MODE—Indicates that a port pair is configured for DPT/SRP.

The port LEDs might not go on until after you have configured the PLIM interfaces (or turned them on, if they were shut down). To verify correct operation of each interface, complete the configuration procedures for the PLIM (see Cisco IOS XR Interface and Hardware Component Configuration Guide). Table 10 shows the different operating states of the PLIM LEDs.

For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.

Cisco Technical Support Website

The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
