Can you wiggle it out part way to see the configuration?  Maybe use your
camera to snap a picture that you can examine at leisure?  There's some
risk of unpowering it, but unless they are medical devices, you may be able
to handle that.

I thought about that, but not only am I not local, asking a local tech 
to try and them pulling it out too far would be a career-limiting move 
:-)

Yes, twist lock. The devices in question are UPSs, and are 2880va, 120v 
units. And it may be confirmation bias, but 2880va/120v = 24a, which is 
80% of 30a, the standard derating. So I'm inclined to believe they are 
L5-30, especially since one unused one in the rail of 10 outlets is 
(local guy was able to unplug an unused unit). Does that make sense or 
am I thinking wishfully here (I have an order ready to go for mew ones 
with L5-30 plugs, just waitng for the outlet specs).

Can you work backwards by having your local hands and eyes team send you 
the UPS model #s and then find the corresponding specs (or photos) from 
the manufacturer(s) ?

Jim - If they are UPSs (Uninterruptible Power Supply), if you unplug=20
one/them the devices plugged into the UPS should just keep on working=20
and not be affected. (Otherwise, there is a much larger problem here.)

On the other hand, I am a jinx when it come to power failures and backup=20
power. I have been present at more clients than I can remember where=20
there was a loss of power and the backup failed. Each failure was=20
different, but all when analyzed fell into the category of failure to=20
adequately validate the system.

So, in principle you SHOULD be able to unplug the UPS and see what kind=20
