AlphaServer ES40 "12v Bulk Warn"

Our ES40 has display a "12 volt Bulk warning" message on the front of the operator display. The system is still operational.......
After looking up the message on the operators guide, it indicated that there was a + or - voltage threshold on the power supply. We had our local provider order a power supply for the system. Has anyone out there run into this before, if so what was your solution ????

Re: AlphaServer ES40 "12v Bulk Warn"

Dear Jim

I had a similar problem in one of my ES40 server, so just swap the supply & check , if u get same message in that case u need to replace the system board. U can confirm this problem by following steps

(1) shutdown the system & go to SRM prompt

(2) give rmc command & give password, here
u will see that any one (+12 or -12V)
supply will not showing properly.
(3) If u don't get the proper voltage means
u have to replace the system board

Just follow the steps cintan suggested. But I suspect that your power supply gone, you may need to change the power supply.

Thanks for the reply on this issue. The out come on this was that we did have a bad system board. I did try the power supply at first, but when that did not resolve the issue I replaced the system board and the problem went away.

Thanks again
