Chapter 9 Replacing DRAM on the Route Switch Processor
Upgrading or Replacing DRAM DIMMs on the RSP4 and RSP8
by your DRAM upgrade requirements, or to the Cisco part numbers on the DIMMs. DRAM upgrades
require the removal of the RSP4 or RSP8, so plan your DRAM upgrade to minimize your system
downtime.
Figure 9-4 RSP4 DRAM DIMM Locations
Note Each RSP4 DIMM socket has one plastic lever on one end, which is used to remove the DIMM from its
socket.
Caution To prevent memory problems, DRAM DIMMS must be 3.3V devices. Do not attempt to install
higher-voltage devices (such as those designed for the RSP2) in the RSP4 DIMM sockets.
