A problem in restarting the server

[YMJ]

Hi all
yesterday, there was an electricity cut-off in our building, and our UPS can't serve more than one hour. Then, we decided to turn off the server. Next, after the electricity came back, we couldn't the start the server again. we turned on the tape drives, Disk array, then the cpu but the message 'swtich the STANDBY/READY switch to ready' didn't appear.

Hi,
I assume we talk about a T-Class Server, right?
Could you please check the status of all power supplies and the SP and if you find anything unusual come back with it.

Hi Patrick

I check all power supplies, It seems to me OK, But it gives me warrning

[YMJ]

I can't see any service processor running

Was I right that we are talking about a T-Call? It makes troubleshooting much moer simple if we know the name of the beast.
Which powersupply gave you the warning?
