This morning, I noticed this light was flashing on the Dell PowerEdge 2450 and 2550 that we have in our rack -
No warnings as far as i can see on screen...
Any ideas as to what it might be?

Its the PSU light. Usually means one of the several Power Supply Units got disconnected. Check the backside of the server, perhaps a power cable went loose. If it started flashing on both servers, check the sockets/PDU/plugs that are shared between the two servers, perhaps you have a failure in your power equipment. | |||

From the user manual for the 2550:
Not familiar with that model personally, but I'd run some diagnostics. | |||

I'm assuming (because your image didn't post) that the amber light is blinking. The amber light blinking is an indication of an error condition. It could be anything, not just the PS. It could be a memory error, CPU error, PS error, fan error, etc. My guess, based on the fact that both servers are exhibiting the behavior, is that they have each lost power to one of the power supplies. | |||

Do you have a remote management card or software on the server? If so see what it says. If not then you may need to reboot to see what the post reports is wrong. | |||

Well, if it is a PSU failure, then one of the units at the back should be flickering. Generally (assuming it's loaded and available) I'd suggest checking on the Dell Management software which will boil down the errors and warnings on the system. Luckily the Dell mgmt software runs without bringing the machine down to boot off the diagnostics disc/partition, so it's the least interruption. | ||||

I would run diagnostics. But, following are some of the obvious ones to check. 1) DELL PE2450 has dual power supplies: Check if both the PSUs are normal. 2) Harddisk failure: The LED on the Harddisk would glow amber. | |||

Check to make sure it is not the locate server light. I had a new guy freak out over that. | |||
