Do not put the BBU on a metallic plate, including the chassis of the server.
Do not hold the BBU with wet hands.
If you do not follow these directions, the battery may be short-circuited.
6-2. Notes on Operation
The life of the battery pack used for the BBU is about 2 years, which may vary a little depending on
the environment of use and the environmental conditions. Replace the battery pack with a new one two
years after the installation. For the replacement, contact your service representative.
To manage properly the BBU states, install the "MegaRAID Storage Manager" RAID Controller
Management Utility. The MegaRAID Storage Manager allows you to detect errors and check the BBU
states.

- When the battery is missing
The battery hardware is missing or malfunctioning, or the battery is
Unplugged, or the battery could be fully discharged. If you continue to

and this message continues to appear, then contact technical support for
assistance.
