The battery on the RAID card is dying. You'll want to at least remove it so it doesn't make a mess inside your server.

The batteries are on the RAID card. They allow a feature called write-back: Writes to disc are temporarily held in RAM so they can be better ordered to improve performance. The batteries are needed in case the server looses power and can't write the data to disc (which it claimed to the operating system that it had written to disc). Next time the server powers up, the RAID card will flush those writes to disc. If the RAID card detects the batteries are dead, it will disable this write caching, which can impact server performance.

You don't mention which exact model of server you have. On the HP based servers, (which I think this is, based on the message) the batteries are quite easy to replace: Power the server down, pop the lid, and you should see a battery module on the RAID card near the back. On the MCS7845-H (Which is a rebranded HP DL380G5) the batteries are clipped onto the RAID card and connect through a small fly-lead. The batteries on the RAID cards on the MCS 7845/DL380G5 are dire. We had to replace all our batteries at least once.

Gordon, thanks for replying..

My server is IBM based MCS7835H2. I'm wondering if the server flash the alarm even if the electrical power not shutdowns the server ??. cause i have another server in the same rack both on the same power supply and there is no alarm on the second one.
