We've recently acquired a Dell 1855, that we've got populated with 4 blades. I've got it mounted, powered up, and ready to go. Except for the fact that i can't get any of the blades to recognize/boot from the supplied USB CD-Rom. I've tried other blades, and i've tested the USB Cdrom. I've tried other blades in other locations. I've researched the appropriate BIOS settings, to no avail.
Also (possibly related?), 3 out of the 4 blades blink amber LED's at me. I can see in the web portal that there are warnings, but i don't know what to do to get detail to go about fixing/clearing them.
any help at all would be *Greatly* appreciated.
