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.)
