Physical Layer Interface Modules
A physical layer interface module (PLIM) provides the packet interfaces for the routing system.
Each PLIM is paired with a modular services card (MSC) through the chassis midplane. Each MSC and PLIM pair is installed in corresponding chassis slots in the chassis, on opposite sides of the chassis, and mate 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).
The Cisco CRS 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.
•The 4-slot chassis supports from 1 to 4 PLIMs.
Note Although the 16-slot chassis supports up to 16 PLIMs, the actual number of PLIMs supported may be a smaller number. This may be the case on certain multichassis systems that incorporate SPAs or interface PLIMs to receive traffic into, and route traffic out of, the Cisco CRS router.
For additional information about the operation of MSCs and PLIMs, see Cisco CRS Carrier Routing System Line Card Chassis System Description for the 16-slot, 8-slot, or 4-slot chassis.
Carrier Grade Services Engine PLIM Overview
The Carrier Grade Services Engine PLIM provides Service Engines (SE) capability, which implements services outside the Route Processor. Packets are diverted inside the chassis to the SE for processing. There can be multiple SE's in a chassis, and each SE can support a single service or multiple services.
In addition, PLIMs include power and clocking components, voltage and temperature sensors, and an identification EEPROM that stores initial configuration and PLIM hardware information.
The Carrier Grade Services Engine PLIM has the following features:
•Online insertion and removal (OIR)
•Network management: Cisco IOS XR CLI, XML, and Craft Works Interface (CWI)
•Compliance with network and industry standards

Before You Remove or Install a PLIM
Review the following sections carefully before you remove or install a PLIM:
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 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 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 DC-input power system.
•Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed wiring of a CRS configured with the DC-input power system.
•Make sure that you provide short-circuit (overcurrent) protection 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:
•The 20 Gbps Carrier Grade Services Engine PLIM can be placed in any of the upper slots of the 16-slot Cisco CRS-1 or Cisco CRS-3 line card chassis.
•To place the 20 Gbps Carrier Grade Services Engine PLIM in a bottom slot of the 16-slot Cisco CRS-1 or Cisco CRS-3 line card chassis, the corresponding upper slot must either have another 20 Gbps Carrier Grade Services Engine PLIM installed, or be empty.
•The 80 Gbps Carrier Grade Services Engine PLIM can be placed in any of the upper slots of the 16-slot Cisco CRS-3 line card chassis, the corresponding bottom slot must either have a 80 Gbps Carrier Grade Services Engine PLIM installed, or be empty.
•To place the 80 Gbps Carrier Grade Services Engine PLIM in a bottom slot of the 16-slot Cisco CRS-3 line card chassis, the corresponding upper slot must either have a 80 Gbps Carrier Grade Services Engine PLIM installed, a 20 Gbps Carrier Grade Services Engine PLIM installed, or be empty.
•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.
•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 4).
Figure 4 Ejector Levers and Captive Screws
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:
Removing a PLIM
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
To remove a PLIM, see Figure 5 and follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2 Loosen the two captive screws holding the card in place.
Step 3 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 4 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.
Step 5 Place the PLIM directly into an antistatic bag or other ESD-preventive container.
Step 6 Insert another PLIM or an impedance carrier into the empty card slot.
Figure 5 Removing or Installing a PLIM
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
To install a PLIM, see Figure 5 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 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 in the chassis 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 If this PLIM is new, configure it for operation. For instructions, see:
Verifying the Installation of a PLIM
This section describes how to verify that a PLIM has been properly installed. See Figure 1 for the location of the port and Status LEDs on the front panel of the 10-GE PLIM.
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 chassis) or the route processor (8-slot and 4-slot chassis). See Cisco CRS 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 and 4-slot chassis) to see whether the chassis, as a whole, is receiving power.
•Use the LEDs on the PLIM to verify the correct installation and operation of the card.
•The card remains in "IOS XR RUN" state until you install the appropriate service package.
•After you install the service package, the card remains in "FAILED" state until you complete the configuration. To complete the configuration, perform the steps at:
Getting Started with the Carrier Grade NAT. Perform the tasks in this section to get started with the configuration tasks:
–Configuring the Service Role
–Configuring the Service Instance and Location for the Carrier Grade NAT
–Configuring the Infrastructure Service Virtual Interface
