DIMM Replacement Procedure

In the event that the Dual In‐line Memory Module (DIMM) needs to be replaced, the following sections explain how to remove and install the DIMM. If you have questions concerning the replacement of the DIMM, refer to “Getting Help” on page xviii for details on how to contact Enterasys Networks.

Removing the DIMM

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 the existing DIMM, proceed as follows:

1.Remove and save the seven screws attaching the safety cover to the standoffs on the main PC board.

2.Locate the DIMM connector on the main PC board. Refer back to Figure B‐2 for the DIMM location on the 7H4385‐49.

3.Push the connector arms away from the DIMM, as shown in Figure B‐7, and simultaneously lift the DIMM enough to release it from the connector fingers.
