Line Card Chassis System Description.
Installing an RP, PRP, or DRP Card
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 contains two RP cards in dedicated slots on the front (PLIM)
side of the chassis (see Figure 4-28).
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 the Cisco CRS-X system, you must use PRP cards only.
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.
Prerequisites
Because chassis operation may be impacted by the installation of a route processor card, perform these
tasks only if one of the following conditions exists:
• When you are certain that the second RP in the chassis is operational and, if not already the active
RP, ready to assume control (this happens automatically)
• When the chassis is undergoing scheduled maintenance
• When the Cisco CRS 8-slot line card chassis is powered down
Failure to follow these guidelines can result in interruptions in data communications and network
connectivity.
