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.
To install a new NVRAM backup battery pack in a server, you must remove
the battery caddy. If you have a replacement battery without a caddy, you
can replace the battery inside the caddy, then reinstall the caddy.
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.
Checking battery pack status
The battery pack status LED indicates the status of the server's NVRAM
battery pack.
Table 6-1 Battery pack status LED
LEDs Meaning
Red
If this LED is on immediately after installing a new battery pack, it indicates that
an initial battery charging and conditioning cycle is in progress. The initial
battery conditioning takes approximately 24 hours, and the LED will turn off
after the cycle is complete.
If this LED is on during normal operation (not after installing a new battery
pack), either the battery has exceeded its two year life or a problem has been
detected. Check the battery status before determining any service operation.
Off
Normal operation.
