Re: Blue LED

Is this the (UID) Identification LED? It should be on the back as well. It is harmless, it is an LED that lights up in the front and the back of the server to identify the server when you are working on it. You press the LED again in the front or the back to turn it off.

It is very useful when you have servers that are stacked up on a rack. When you work on a server and you go from the front to the back to pull a wire or a component, you light this up and you know which server you are working on.

Flashing means you have the remote management (console?) connected to the server.

Re: Blue LED

Sometimes the light stays on. And you can't switch it of with the button. the you need to logon to the ilo and do a reset of all active connections.

Re: Blue LED

If it is flashing, see above. Once you disconnect the remote management session it will go out.

If it is solid, you can turn it off in the back of the server. The blue light in the back of the server is also the switch to turn it off.

Did you see page 75 in the URL above? Item #2 "UID LED and button". Not sure but the front LED may be a switch as well.

Re: Blue LED

The UID LED is a switch as well. You can press the UID button to turn it off. Also, the UID button can be turned off using ilo.
