RE: Warning light on secondary cabinet of 520 ^H^H^H OOPS, I meant 510

 Be aware that the disk controller actually has it's own batteries.

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.
