Replacing the NVRAM backup battery pack
To replace the NVRAM backup battery pack in a server, you remove the old
battery and install the new replacement. Perform the battery pack
replacement as quickly as possible, and only when the new pack is present.
Note: If possible, shut down the server before replacing the battery backup
pack. Shutting down the server or migrating all of the EVSs to the other node
is not required. However, during the replacement procedure, there will be a
period of time when the NVRAM contents are not backed up by the battery
pack. If a power failure occurs during this period, the NVRAM contents may
be lost. The server uses one of two types of chassis:
• Type 1: Without a battery retention bracket.
• Type 2: With a battery retention bracket.
This section explains how to change the battery pack in both types of chassis.
Note: Replacement battery pack wires may be unwrapped, or they may be
wrapped. Wire routing is identical for both, but additional care is required
when the wires are not wrapped to ensure that they are correctly placed and
that they do not get pinched between parts.
Removing the battery pack from the caddy
Prepare the new battery. Separate the battery pack from the caddy (module
case).
Procedure
1. Loosen thumbscrew on the rear of the caddy (the side with the electrical
connector).
