Upgrading and Replacing DRAM SIMMs

VIPs are shipped with 8 megabytes (MB) of dynamic random-access memory (DRAM) as the default DRAM configuration. Depending on memory requirements, you might need to upgrade the amount of DRAM by replacing the DRAM SIMMs on the VIP. You also might need to replace a single SIMM in the case of a diagnosed DRAM SIMM failure.

Note DRAM SIMMs should be upgraded or replaced in the field by a Cisco-certified maintenance provider. Both DRAM SIMMs are replaced for all upgrades.

Caution SIMMs are sensitive components that are susceptible to ESD damage. Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM). (See Figure 10.)
