Hp Proliant DL580 g2 will not power on

Hi everyone,
I received a call from a friend who has a server HP PROLIANT DL580 G2 that was working fine until this friend shut down the server properly, unplug the server to plug it into an APC battery
and He says that the server will not power on but the lights on the server turn on only so he try to connected to the power outlet but it will not power at all as before.
Please advise as I will go tomorrow very early in the morning to help him.

I would try plugging it into a different outlet, and powering it on.  If that doesn't work, the first step I would take is changing the power supply.  Generally it's quite easy to change them, at least to test if that fixes the problem.

Firstly pop out the power supply and push it back in. If it has a 2nd power supply try connecting the second one.

Other things could be that the server is turning on but there is no output on the screen. This could indicate a RAM problem. Try removing then reseating the RAM.

Another thing very with old servers is that if you don't have a keyboard attached to it when it turns on, it won't make it past the POST. So try getting a PS/2 Keyboard and mouse with a Monitor all plugged into the server and see what comes up on the screen.

Try the secondary power supply unit. It also could be the a problem with the power on switch on the server. I had a problem with the power on switch of a DL380.

Hi, HP PROLIANT DL580 G2 should have iLO controller.
1. Check iLO presence (should be LAN connector marked as iLO), look for login requisites (lable on server case)
2. Connect server to outlet or battery (server can be switched off, but some lights should indicate AC connection)
3. Connect LAN cable in to iLO port (should be DHCP server available to get IP address of connected Server)
4. From any computer from the same network, in explorer type IP address if iLO (step 3), login using requisites (lable, step 1)
Using iLO WEB you can get status of Server from LOG, you can switch it on if power on switch defective, you can update some firmware if require.

Check Proper connection and Power voltage through Multimeter. it is 230V is proper or not. If power is ok then check with the Power cable.
