Server will not power up

In preparation for a recent hurricane, I powered down my server and unplugged both power supplies from the UPS. Now that the storm has passed and our commercial power has been restored, the server will not power up. The server has (2) DPS-730AB A power supplies. Each power supply has a red and a green LED neither of which will light up. I have confirmed that there is power to the outlet and that the power cords are not the cause of the problem.

It seems odd that both power supplies would fail at the same time.

Any suggestions or troubleshooting tips that can be offered are greatly appreciated.

I'd just wait for an hour or so with the power connected, then try powering it back on.

I agree with the above. Were the servers on a UPS and does it need to charge and/or reset?

Since it has 2 PSUs and neither come on then I'd plump for the power distribution board that connects the PSUs to the motherboard etc.. Presumably you have tried with just one PSU in each slot and then the other PSU in each slot.

The LEDs are not that informative on these PSUs, AFAIK they aren't driven directly from the PSU but via I²C (or I2C if the font renders "squared" symbol badly).

Might be worth looking through https://www.experts-exchange.com/questions/21865463/Can't-Power-Up-Server.html as they have a similar PSU.

You can partially test the PSUs by connecting PSON to GND **I think** although http://www.rcgroups.com/forums/showthread.php?t=1005309&page=47 says connect both PSON and PS-KILL to ground to power up. You do this outside the box of course, you don't want to blow the motherboard up and you'll need a DVM to check for 12V output although you could use a LED and a resistor if you don't have a DVM.

Have you tried reseating the PSU's?

You were given good answers here.

May we assume you threw the server in the garbage can and started fresh?
