First of all: Sorry if I've missed something obvious. I've tried to read all available documentation, but haven't found any hints.... I have some experience with Poweredge 2850 and 2950 servers (mainly replacing a HD or a PSU), but this is all new to me.

I was asked to have a look at a Poweredge 2850 one of our offices replaced because it "wasn't working properly". It has been collecting dust for a few weeks until today when I plugged it in. At first, everything looks fine: Green LEDs on PSUs light up (one LED on each PSU), LCD on front displays standard message ("Dell PowerEdge 2850" or something similar) and power button blinks green. But that's just it: The server won't start. Nothing happens when I push the power button, it just keeps flashing. The i-button works just fine (blue LED on back lights up + LCD lights up for a few seconds) but nothing else happens. Any help is appriciated! Thnx!
