OOPS, it's a 510, not a 520!

It isn't. None of our boxes are. We have enough geeks around the office to do our own repairs, and a dead 500 (which we obtained in the same customer barter deal as the 510) that's been a good source of spare parts.

As soon as I broadcast my question, I started hunting around for the manuals for the 510. It took a while to find where they'd been moved to, but once I found them, the Problem Analysis book was near the top, and I found a probable answer: 1xxxyyyy is power supply, and yyyy=D201 is a bad internal battery pack.

I didn't know expansion boxes HAD their own battery packs; at any rate, if it's a battery (can anybody confirm?), it's irrelevant, since that whole system is on a UPS, with a monitoring cable.
