Depending heavily on the system and the BIO, you may have 3 "Power
Recovery" options when coming back from a power failure.
* Power Off
* Last State
* Always Power On
Sounds like you need option #3 if your system supports it.</pre>

It's an elderly ATX box (mini tower) that has a relatively new MB
and PS.<br>
<br>
Sounds like I'll have to test it. It has that option. My only
concern is "how does the computer know the power is back?" It's
connected to a UPS, I shut it down orderly and power off and the
power to the computer is never interrupted unless the UPS battery
runs down. I'd have to shut the UPS off too.<br>

Is this a rack mount server or are you sticking a desktop / tower system
somewhere?
Someone mentioned the AMT module. That's the Intel Active Management
Technology module. A lot of modern rack mount equipment has these
things but, most of the time, they haven't been enabled. There's all
kinds of gotcha's in setting them up securely for distant remote
control, however, and it's generally recommended they be accessible only
from the local network.
Another option if your server doesn't have an AMT, and doesn't support
the Always Power On BIO option, would be to drop a little firmware based
device, like a cheap Linux based router or a Rasberry Pie or something,
that doesn't need to be on backup but will recover when power recovers
and can be connected to remotely. Then you use it with Wake-On-Lan,
which a tower or a rack server SHOULD support, especially if it has on
MB network interfaces. </pre>

I'm surprised it doesn't have wake-on-lan. Other systems I have
here do.<br>

<pre wrap="">Power comes back on, you just connect into your
little interface and use ether-wake to wake up your server. Wake-On-Lan
uses a non-routable packet so you have to have some sort of minimal live
device on the local network to the interface that has Wake-On-Lan
enabled.
The little box could, if it has a serial port (or USB port that will
take a serial dongle), double as a serial console for when you really
get things hosed up. :-P You could get away under $100 that way.
Another option is that some servers and BIOS support timed wakeups.
You'll have to explore your BIOS for that and I've never played with it
personally.
OTOH... If your box you want to remote doesn't even support Wake-On-Lan
(which has to be enabled in the BIOS as well) you probably should look
at a better box. Champagne taste on a beer budget only goes so far.</pre>

If I hadn't just recently put this together, I'd agree.<br>
