Replacing DRAM on the Route Switch Processor

This chapter describes the procedures for upgrading or replacing dynamic random-access memory (DRAM) on each of the RSPs used in the Cisco 7500 series routers. The RSP2 uses DRAM single in-line memory modules (SIMMS), and the RSP4 and RSP8 use DRAM dual in-line memory modules (DIMMS).

All DRAM upgrade procedures are discussed in the following sections:

•Upgrading or Replacing DRAM SIMMs on the RSP2, page 9-1

•Upgrading or Replacing DRAM DIMMs on the RSP4 and RSP8, page 9-5

Upgrading or Replacing DRAM SIMMs on the RSP2

This section describes the procedures for replacing up to four DRAM SIMMs on your RSP2. You obtain the SIMMs from Cisco Systems.
