By | February 11, 2012

If you Dell PowerEdge server have a PERC Raid controller, you may get a warning after the bios controller has started during the boot and of course, a amber diagnostic light flashing on font and back of the server telling you something goes wrong with the hardware!

If you get a front display, it will show up the following error :

E1211 ROMB battery failed

This indicate something is wring with the Raid controller backup battery :

– The battery may be discharged (often happen when the server was off for a long time – it may took an hour to reach full charge)
– The battery is not properly connected
– The battery need to be replaced
