If you put the wrong p/s modules in the old fc7/8/9 shelves, you tended to get a slow-motion "rolling smoke" rather than flame out + sparks, usually with the silver 110's plugged into 208v, but YMMV. I've only seen that on a couple in a cabinet, but you don't forget it. :)
IIRC you wanted the green ones -- they auto-switched. Silver was 110v only, and there was a gold and a copper which were "better" in some fashion than silver, but I don't remember the details.
All better than the lil' brown DEC shelves ....

Ive seen that, but at scale. Was in PS at Netapp, and I was asked to sit-in on a customer moving racks of 500s, 600s, and a few 700s from telco racks to cabinets. At the time the cabinets were 240v only. I was in another room...sit-in help as needed, I was not allowed in the DC.
They made a show of 'lets hit the breakers and turn on all 11 cabinets at once'. Most of them were full of shelves with 120v only power supplies, at the time I think that was "green button" supplies.
Lots of oil..lots of fire.
Replaced 100+ supplies with switching ones, and all was good in the end.
Them was the dayz..

Semi-seriously though, I once had a very old original DS14 shelf p/s (the ones with the vertial bar handles) flame out at me.?? We'd just finished re-racking the rig, so I flipped on the breakers and moved down the row to start on the next one, when the p/s spat out a small and brief burst of smoke and spark.
It wouldn't have been harmful and probably wouldn't have even left a mark, but it was still a surprise.

This could be fun...and old F760 with say, 4 shelves of 36G drives..
Replace the NVRAM battery, check power supplies for leaking capacitor oil...reseat cards and DIMMS...
What're the odds it'll work, and any other fire-prevention steps to take??????? :)
