How to Remove a Memory Module

Memory modules for this system are dual inline memory modules (DIMMs). Each
DIMM bank must contain four DIMMs of equal density (for example, four 64-Mbyte
DIMMs) to function properly. Supported DIMM configuration options are 32, 64, and
128 megabytes. See the Sun Enterprise 220R Server Owner’s Guide for more
information.

DIMMs are made of electronic components that are extremely sensitive to

static electricity. Static electricity from your clothes or work environment can destroy
the DIMM. Always wear a grounding strap when you handle the modules.

Caution -

Do not remove any DIMM from its antistatic packaging until you are ready

to install it. Handle the modules only by their edges. Do not touch the components
or any metal parts. Always wear a grounding strap when you handle the modules.
