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..

Don't stand directly behind it when you turn it on. :-)

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.
