Replacing a Memory Unit

Memory units are located within a processor multifunction (PMF) CRU. S7000 and

S70000 memory units can be replaced in the field, while all other memory units must

be replaced by a manufacturing facility authorized by HP.

To replace a memory unit, the PMF CRU containing the memory unit must be removed

from its enclosure. The following is a summary of the tasks involved in replacing a

memory unit in a NonStop S-series server.

1 Use the appropriate OSM action or guided procedure to remove the PMF

CRU from its enclosure. See Guided Procedures for more information.

2 Follow the instructions in the online help for the action or procedure to

replace the memory unit within the PMF CRU.

Note: These instructions were written for one specific scenario but apply

no matter what your reason for replacing memory. The possible reasons and

strategies are listed next.

3 Resume the PMF CRU replacement procedure in the action or procedure to

reinsert the PMF CRU in its enclosure.

A memory CRU might be replaced for a variety of reasons using appropriate

strategies:

enclosure.

Remove the memory CRUs from the

PMF CRU.

Install the upgraded memory CRUs

on the PMF CRU.

Reinstall the PMF CRU in its

enclosure.
