Hello,
I recently purchased 2 Dell 1100W server PSUs from ebay. I wanted to get them to run outside of a server to use them as power supplies for projects. I can return them if they don't work. Both are model: L1100A-S0 PS-2112-2D1-LF.
I'm following the tutorial located here, but I'm using aluminum pieces as conductive clips (see pictures) instead of soldering so I can return the PSUs if they don't work:
I also saw this pinout diagram here (it's a little more than 1/2 down the page): https://www.rcgroups.com/forums/sho...lity-12Volt-100Amp-Power-Supply-Part1/page273
With -PS_ON connected to RETURN (fourth pin in to fourth pin in top to bottom), one of the PSUs doesn't have it's green light turn on or the fan spin up (I suspect it's dead). The other does have it's green light turn on, but it doesn't turn yellow like in the video. I waited 30s, the fellow in the video waited ~17s. It also doesn't have any power on the 2 big pins.
I tried also connecting pin 29 and 30 to RTN (large pin) using a pair of wires and my fingers but that didn't change anything.
Any ideas on how I can get either one of these to work or are they both DOA? (Dead On Arrival.)
Thanks
