•
Whenever you handle a module or supervisor engine, always use a wrist strap or other grounding device
to prevent electrostatic discharge (ESD). For information on preventing ESD, see the "Preventing ESD"
section of the Site Preparation and Safety Guide.

Upgrading the OSM Memory

This section provides the procedures for removing and replacing the memory on the OSM.
The synchronous dynamic random-access memory (SDRAM) on the OSM is contained in one small
outline dual inline memory module (SODIMM). (See
The OSM has a default memory configuration of 64 MB with Error Checking and Correction (ECC)
(single-bit error detection and correction; 2-bit error detection) and is upgradable to 128 MB, 256 MB,
or 512 MB.
Note You should use only 100-MHz SDRAM SODIMMs. A Cisco part number appears on the SODIMMs.
Caution To prevent ESD damage, handle the SODIMM by the card edges only. (See
Place the removed SODIMM on an antistatic mat or store it in an antistatic container.
