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!
