Power supply on the floor?
Never seen a server with a separate "power brick", but I'm surprised they didn't think to swap it out sooner when they had swapped out everything else. Old school SCSI gear was surprisingly finicky about power.
Though I have to admit I was expecting the tale to end with everything having been replaced except the SCSI cable, and one pin was going to be ever so slightly shorter than the rest. Having a pin that gets "pushed in" just a bit, rendering a cable as working but not 100% of the time, was something I ran into more than once back in the day. Though IIRC with Ultra Wide SCSI cables that used more / smaller pins not the original brand of SCSI with the stout pins where it would be easier to notice when something like this occurred.
