Memory Locations and Replacement Procedures

DIMM Replacement Procedure (4H4282-49 and 4H4283-49)

Caution: Observe all Electrostatic Discharge (ESD) precautions when handling sensitive electronic equipment.

Precaución: Al trabajar con equipos electrónicos sensibles, tome todas las precauciones de seguridad para evitar descargas de electricidad estática.

To remove and replace the DRAM SIMM on the 4H4282‐49 or 4H4283‐49, refer to Figure B‐8 and Figure B‐9 respectively, and proceed as follows:

Removing the DRAM SIMM

Note: Prior to removing the DRAM SIMM in a 4H4282-49 or 4H4283-49, you must remove the Network Expansion Module to gain access to the DRAM SIMM memory and connector.

1.If there is an optional NEM installed on the main board of the 4H4282‐49 or 4H4283‐49, proceed to step 1a. Otherwise proceed to step 2.

a.Remove and save the three screws attaching the NEM to the standoff on the main board and front panel.

b.Lift the NEM straight up and off the two module connectors on the main PC board.
