When I was Dell certified in Desktops, Servers, and laptops I had access to all the Dell manuals online which made it very easy to look things up. My certs ran out and I never renewed but I can tell you
two things that work for me when most others fail- 1) get a second pair of eyes on it- sometimes it's right in front of you but you can't see it. 2) Take a breath and walk away then come back later and look at it again.
I'll bet one of those two will work. I've done alot of Dell servers and the hot swap power supplies are usually a locking latch handle or tabs that hold it in. After all it's supposed to be easy to swap out right ?
good luck- wish I had one to look at so I could let you know.
