Can Dell Poweredge 2500 server restart automatically after power cut?

Posted on 2009-02-11

I have a server that does not automatically restart when power is restored after a power cut now that it is gracefully shutdown by a UPS. Is there a solution?

I have just recycled a surplus Dell PE2500 server with W2K3 server from our main office to a branch office, where it is now a) protected by UPS and b) ADDC / DNS / DHCP for the office. The UPS is a HP r3000XR with HP Power Manager software, although this doesn't have a bearing. The controlled shutdown side is all sorted, as is the staggered load segment delays at restored power to make sure the LAN and WAN are up before the DC, and that before the rest of the apps/file/print servers. The problem is that the PE2500 does not restart when power resumes.

I'm on BIOS A07 (apparently latest) which was necessary to upgrade from W2KS to W2K3, and there seems no option for power on, such as always start / previous state / stay off. I have seen elsewhere at EE a method to short green to black on a PSU to tell the PSU "always start", but wondered how/if that is going to work with the 2 x PSU and PDM. Am I missing something, or backing a loser?

Failing that, to avoid a drive out just to open the rack and press a button, there doesn't seem to be a Wake on Lan BIOS option either, although I have seen reference to the feature in relation to PE2500.

Any guidance gratefully received.

    If you can't find a BIOS option you can always set Windows to sit at the "safe to power off" screen, then Windows will not change the power state so it will start up when powered off/on again by the UPS. (ignore the hotfix info and skip to the more information section on how to set the policy).

    Hi andyalder. I never realised this was a policy setting! I'm sure you're right and will give it a try over the next day or two now I've changed the setting. I'm pretty confident 500 points will be coming your way real soon.

    There is normally a BIOS settinig, the Windows power policy is just a workaround if there isn't one.

    Great workaround andyalder. Worked a treat, although it eats into the the UPS runtime by leaving at least some of the server power on. My aim was to shutdown the servers then leave as much UPS power as possible available to keep the PoE switch, router and WAN link up and running for the VoIP phones, but I guess we can't have everything. Thanks.
