We've had a couple of drive failures on some of our PE2650's and 2950's which haven't resulted in the good old "red alert" style beeps from the internal speaker.  I've only noticed they had failed when in the comms room doing maintenance on other servers and caught the blinking orange light out of the corner of my eye.

Is there any way to enable those beeps without having to take the servers offline?  I've had a quick look in OMSA and can't see anything obvious.

If not, can anyone tell me which menu it's under in the card BIOS?
