6. Notes
Read the following notes thoroughly before using the BBU.
6-1. Notes on Installation
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.
To install the BBU in the server, a single PCI slot of the server must be used. Before starting the
installation, make sure that a PCI slot remains unused.
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 use environment and environmental conditions. Replace the battery pack with a new one after
about two years from the installation. For the replacement, contact your service representative.
To manage the states of the BBU properly, install the Disk Array Controller Management Utility
"Web-based Promise Array Manager" (called WebPAM hereafter). WebPAM allows you to detect
errors and check the states of the BBU (including voltage and temperature).
The following alert may be logged when you restart the system immediately after charged the BBU,
however, you can ignore it. If you continue to charge the BBU, the alert will no longer be logged.
"Battery voltage is out of range"
