Replacing an LSI Battery Backup Unit
In the Cisco UCS C250 server, the battery backup unit (BBU) is installed directly onto the LSI controller
card.
Note A cable is shipped with the BBU that is used for installing the BBU on a bracket in other server models.
Do not use this cable in the Cisco UCS C250 server; install the BBU directly onto the LSI controller
card. Connecting the extra cable causes error messages because the multiple connections are detected as
multiple BBUs (an unsupported configuration).
Note
LSI recommends that you replace the LSI BBU once per year or after 1,000 recharge cycles, whichever
comes first. Verify whether BBU replacement is required by looking in the CIMC. Log in to CIMC for
the server, then click
Server — Inventory — Storage — Battery Backup Unit . If the Battery Replacement
Required field says, “True,” then you must purchase a replacement BBU and replace it.
Warning There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the
same or equivalent type recommended by the manufacturer. Dispose of used batteries according to
the manufacturer’s instructions.
