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 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.
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.

The 20 Gbps Carrier Grade Services Engine PLIM has no physical interfaces. Figure 1 shows the front panel of the 20 Gbps Carrier Grade Services Engine PLIM.
Table 3 describes the PLIM LEDs.
The 80 Gbps Carrier Grade Services Engine PLIM is a multiservice PLIM that performs Layer 4 to Layer 7 services in the Cisco CRS-3 Carrier Routing System. The 80 Gbps Carrier Grade Services Engine PLIM occupies one PLIM slot of the CRS-3 chassis and works in conjunction with the CRS-MSC-140G to provide Service Engine functionality. The 80 Gbps Carrier Grade Services Engine PLIM is capable of handling 80 Gbps of application traffic.
The 80 Gbps Carrier Grade Services Engine PLIM has two Control Ethernet ports located on the front panel. Figure 2 shows the front panel of the 80 Gbps Carrier Grade Services Engine PLIM.
Table 4 describes the PLIM LEDs.
A PLIM impedance carrier must be installed in each empty PLIM slot in the Cisco CRS chassis (see Figure 3). The impedance carrier preserves the integrity of the chassis and is required for EMI compliance and proper cooling in the chassis.
- 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.
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.
- 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.
- 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).
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.
To remove a PLIM, see Figure 5 and follow these steps:
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.
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.
To install a PLIM, see Figure 5 and follow these steps:
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.
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.
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.
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.
- 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:
