Gaining Access to Memory Modules
Before you can replace the DRAM SIMM, you must gain access to it by removing the
safety cover and the network expansion module, if one is installed. To gain access to the
DIMM, you only need to remove the safety cover.
Removing the Safety Cover
Refer to Figure B‐3 and proceed as follows:
1. Attach the antistatic wrist strap (refer to the instructions on the antistatic wrist strap
package).
2. Place the DFE module on an antistatic pad on a sturdy flat surface.
3. Remove the seven screws fastening the safety cover to the seven standoffs on the main
board. Save all screws for later use to reinstall the safety cover.
4. If you need to replace the DRAM SIMM, proceed to “ DRAM SIMM Replacement
Procedure ” on page B‐7. If you are replacing the DIMM, proceed to “ DIMM
Replacement Procedure ” on page B‐10.
