Replacing and Upgrading Route Processor Route Memory
Removing Route Memory DIMMs from an RP
Review the following route memory removal scenarios:
•
•
Note
After removing processor memory DIMMs from the RP, place them in an antistatic bag for ESD
protection. Removed route memory DIMMs can be used in other compatible equipment.
To remove a DIMM from an RP, follow these steps:
Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection
Step 1
sockets on the front of the chassis or to a bare metal surface on the chassis.
Position the RP on the antistatic mat so that the faceplate is toward you and the backplane connector is
Step 2
away from you.
Locate the route memory DIMMs on the RP. (See
Step 3
(bank 2).
Step 4
For the DIMM you want to remove, pull down the lever on the DIMM socket to release the DIMM from
the socket. (See

If you are upgrading the memory by adding a matching DIMM to an existing single-DIMM
configuration (only socket U39 occupied), use the procedure in the
DIMMs on an RP" section on page
to 128 MB (two 64-MB DIMMs) or from 128 MB to 256 MB (two 128-MB DIMMs), you can install
the appropriate DIMM in socket U42.
If you are replacing a defective DIMM or performing a memory upgrade that requires the existing
DIMMs to be removed, use the following procedure. For example, if you want to upgrade memory
from 64 MB to 128 MB (one 128-MB DIMM) or 256 MB (two 128-MB DIMMs), you must remove
the existing DIMM before installing the new DIMMs.
