Performance Route Processor Installation and Configuration Guide
OL-11656-01
Note
If your system includes redundant PRPs, both PRPs should have the same memory
size. Redundancy is not supported when using a GRP and a PRP in the same
chassis. Cisco strongly recommends that you avoid configuring your router using
mixed route processor cards. Refer to the
Route Processor Redundancy Plus for
the Cisco 12000 Series Internet Router
publication for more information.
Caution
Only Cisco-approved memory is supported. Do not attempt to install other devices
or non-Cisco approved DIMMs in the DIMM sockets. (See
Table 15
and
Table 16
.)
Removing a DIMM
To remove a DIMM from a line card, follow these steps:
Step 1
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2
Place the line card on an antistatic mat so that the faceplate is nearest to you.
Step 3
Locate the DIMM sockets on the line card.
