Replacing the NVRAM backup battery pack

NAS Platform and Unified Storage Series 4000 Hardware Reference

Part Number

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.

The replacement NVRAM backup battery pack comes pre-assembled. Do not remove the batteries from the case.

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.
