This section contains the guidelines for card installation and removal.

Caution

Removing more than one card at a time can misalign the chassis and may damage the card or chassis when reinserting the cards. Remove and reinsert only one card at a time.

Online (in-service) insertion and removal (OIR) is supported, enabling you to remove and install cards while the router is operating. 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.

The different cards and PLIMs in the line card chassis are all attached to the chassis itself using a pair of ejector levers and captive screws. The two ejector levers release the card or PLIM from its midplane connector. The exact location of the ejector levers and captive screws varies slightly from card to card, but are in general in the same location: on the upper and bottom of the faceplate of the card. .

Figure 1. Ejector Levers and Captive Screws

The following figure shows how to operate the ejector levers. Be sure to operate both levers simultaneously.

Figure 2. Operating Ejector Levers

When shipped, every slot in the chassis contains either an impedance carrier, or is covered by a slot cover (see About Impedance Carriers and Slot Covers).

Note	While it is not critical for you to install the cards in a certain order, following the card installation recommendations in this chapter will make your installation process easier.

Figure 1 and Figure 2 show the slot numbers for the Cisco CRS 8-Slot Line Card Chassis Enhanced router.

Figure 3. Cisco CRS 8-Slot Line Card Chassis Enhanced Router Slot Numbers—Front (PLIM) Side

Figure 4. Cisco CRS 8-Slot Line Card Chassis Enhanced Router Slot Numbers—Rear (MSC) Side

When shipped, all slots in the chassis either contain impedance carriers or are covered by slot covers to help maintain chassis stiffness and ensure that the chassis is undamaged during shipment. Four different types of impedance carriers and slot covers exist for the four different sizes of slots in the chassis.

The Cisco CRS Carrier Routing System provides distributed route processor (DRP) support through the installation of DRP PLIMs and DRP cards on the Cisco CRS 8-Slot Line Card Chassis Enhanced router (see #con_1293320/​fig_​1293331 and #con_1293320/​fig_​1293338). The installation of DRPs provides you with the ability to configure the system for logical router support and additional processor power for multichassis systems.

Figure 9. DRP PLIM

Figure 10. DRP Card

For DRP support, you must install both the DRP PLIM in a PLIM slot on the front (PLIM) side of the chassis and a DRP card in the corresponding slot on the rear (MSC) side of the chassis. The DRP PLIM and DRP cards are installed in the same manner as regular PLIMs and MSCs. See Installing a Physical Layer Interface Module or Installing an MSC, FP, or LSP for further information.

DRPs contain two CPU complexes, independent of each other, each with its own hard drive. In addition, the DRP provides you with two PCMCIA card slots, similar to the RP. For further information, see About Hard Drives and PCMCIA Cards. For installation or removal information, see Installing a Physical Layer Interface Module.

The SFP module for the line card chassis uses the bale clasp latch type.

Caution

Protect the SFP modules by inserting clean dust covers into them after the cables are removed from them. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another SFP module. Avoid getting dust and other contaminants into the optical ports of the SFP modules: The optics do not work correctly when obstructed with dust.

Note	Only the 16-port OC-48c/STM-16c MSC uses SFP modules.

Optional and replaceable hard drives and PCMCIA cards are available for the DRP cards.

The hard drive is an IDE hard drive used for gathering debugging information, such as core dumps from the DRPs or MSCs. The IDE hard drive is typically powered down and activated only when there is a need to store data. The drive is not vital to a functioning chassis and is optional.

Note	Core dumps are discoverable only through intervention with the chassis system software.

Physically, the DRP hard drive is a hot-pluggable PC board and sled-mounted drive with a connector interface that gets cleanly seated into a route processor card. In general, removal and replacement of this drive is not required.

The DRP cards provide two PCMCIA flash slots, each card providing up to 1 GB of flash storage. One of the PCMCIA flash subsystems is accessible externally, is removable, and allows you to transfer images and configurations by plugging in a PCMCIA flash card. The other subsystem is fixed to the DRP, not removable, and for permanent storage of configurations and images.

The Cisco CRS 8-Slot Line Card Chassis Enhanced router includes a cable management system that organizes the interface cables entering and exiting the different cards, keeping them out of the way and free of sharp bends.

Caution

Excessive bending of interface cables can damage the cables.

The Cisco CRS 8-Slot Line Card Chassis Enhanced router arrives preinstalled with a horizontal cable management bracket on the front of the chassis and an optional horizontal cable management bracket is orderable for the rear of the chassis.

Note	If you have Back-to-Back (B2B) installation of fabric cards, it is essential that you use the rear cable management brackets for ideal cable management.

The following figure shows the front cable management bracket.

Figure 11. Front Cable Management Bracket

The following figure shows the rear cable management bracket.

This section describes how to install a slot cover in the Cisco CRS 8-Slot Line Card Chassis Enhanced router. The chassis is shipped with slot covers over the switch fabric card and RP card slots; we advise installing slot covers over any empty slots in the chassis. Both slot cover types are installed in the same manner. For more detailed information on the slot covers, see About Impedance Carriers and Slot Covers.

Figure 12. Switch Fabric Slot (Half Height) Slot Cover

This section describes how to remove a slot cover from the Cisco CRS 8-Slot Line Card Chassis Enhanced router. The chassis is shipped with slot covers over the switch fabric card and RP card slots. Both slot cover types are removed in the same manner. For more detailed information on the slot covers, see About Impedance Carriers and Slot Covers.

Figure 13. Switch Fabric Slot (Half Height) Slot Cover

This section describes how to install an impedance carrier into the Cisco CRS 8-Slot Line Card Chassis Enhanced router. The chassis is shipped with impedance carriers installed in the MSC and PLIM slots. Both impedance carrier types are installed in the same manner. For more detailed information on impedance carriers, see About Impedance Carriers and Slot Covers.

Figure 14. MSC Slot Impedance Carrier

This section describes how to remove an impedance carrier from the Cisco CRS 8-Slot Line Card Chassis Enhanced router. Both impedance carrier types are removed in the same manner. (For reference, #con_1283445/​fig_​1284640 shows an MSC impedance carrier.) For more detailed information on impedance carriers, see About Impedance Carriers and Slot Covers.

This section describes how to install a route processor (RP), performance route processor (PRP), or distributed route processor (DRP) card in the chassis.

Every Cisco CRS 8-Slot Line Card Chassis Enhanced router contains two RP cards in dedicated slots on the front (PLIM) side of the chassis.

Note	A chassis may not be populated with a mix of RP and PRP cards. Both route processor cards should be of the same type (RP or PRP). If you are using Cisco CRS-X, you must use only PRP cards.

Note

For enhanced immunity to external electromagnetic disturbance levels of 10V per meter and 10 V RMS, you must use a shielded Ethernet (CAT5 or better STP) cable on the Management Ethernet connection of the RP card (CRS-8-RP). The use of a shielded Ethernet cable on the Management Ethernet connection of the PRP card (CRS-8-PRP-6G or CRS-8-PRP-12G) is optional. The grounded end of the shielded Ethernet cable should be at the RP (or PRP) end.

Caution

Be careful while handing the PRP line cards to avoid pressing the memory module latches on the daughter board and accidently disengaging the memory modules. For the location of these latches, see the following figure.

Figure 15. Memory Modules Latches on the Daughter Board

This section describes how to install an MSC, FP, or LSP line card in the Cisco CRS 8-Slot Line Card Chassis Enhanced router.

The MSC, FP, and LSP line cards are Layer 3 forwarding engines in the Cisco CRS Series routing system. A line card can be paired with different types of physical layer interface modules (PLIMs) to provide a variety of interfaces.

• The MSCs include: CRS-MSC, CRS-MSC-B, CRS-MSC-140G, CRS-FP-X/ CRS-FP-X-L(400G).
• The FPs include: CRS-FP-140, CRS-FP-X/ CRS-FP-X-L (400G).
• The LSPs include: CRS-LSP, CRS-LSP-X (400G).

A line card fits into any available MSC slot and connects directly to the midplane. If you install a new line card, you must first remove the MSC impedance carrier from the available slot.

Caution

Be careful while handing these line cards to avoid pressing the memory module latches on the daughter board and accidently disengaging the memory modules. For the location of these latches, see the following figure.

Figure 23. Memory Modules Latches on the Daughter Board
