Proliant 6400r wont boot

[Josh Whartman]

I recently bought a 6400r proliant off ebay. It has 2 500mh xenons and 2 gigs of ram. When I plug it in the power light (light bulb) and inter-lock light are both amber. THe fan light is not on because none of the fans are running. On the system board one of the leds in the inter-lock bank are amber. It is labled as "misc" Does anyone know what this amber misc led is telling me? I can't seem to find anything that would prevent the server from booting with the case off, though I've tried it with the case on too. Any help would be appriciated.

Do you have terminator processors boards in the unused processor slots?

Note: Only the left LED in any row can provide a valid indication of error. After ensuring that the server is powered down and
power cables are disconnected from all power supplies, reseat the device associated with the left LED.

Thanks for the help. I ended up just ripping the whole thing apart and I found a loose IDE cable on the system board. I shoved it back in and now it works perfectly. Thanks again.
