PowerEdge R610 E1211 RAID controller battery Failure PERC H700

The front panel display turns yellow and says RAID controller battery failure.  Check battery.

Reading 47 dozen knowledge base articles has not been a whole lot of help.  There is some docs that say that the PERC H700 RAID controller does not even *have* a write-back backup battery, and a physical look at the raid controller (without taking anything more than the top cover off) does not have anything that looks like a battery, not even a "coin" battery -- though there is one of those on the mainboard, but not on the RAID controller.

Does not seem to be affecting machine performance particularly, however having the front panel display an annoying E1211 error code is not great.  

I found a similar post here on these forums with a part number, but can't seem to find that part to purchase (online at least).  The machine is under hardware warrentee (but not support apparently)

So:

1.  How to identify / replace the bad battery (if there even is one)

2. How to turn off the error message on the front panel display

Thanks!

Hello

There is some docs that say that the PERC H700 RAID controller does not even *have* a write-back backup battery

The H700 has a battery. There is not a version of the H700 that does not have a battery.

1.  How to identify / replace the bad battery (if there even is one)

The picture in your second post is the correct battery. The part number is NU209. If you go to dell.com and put that part number in the search field it should display the battery.

2. How to turn off the error message on the front panel display

You can't turn off the error message. The H700 requires a battery for full functionality. If a battery is missing it will always produce an error.

Thanks

can this also cause the server to be shutting down?  each time i powers it on, after 7 to 10 days it shut down again. If not the problem of RAID battery, what might likely cause it?
