Re: Bladecenter H 2880W Breakout Boards. First batch closed, now selling from stock

So I bought a couple of break out boards a few months ago and it seem they are not working now? The fans on the psu wont spin , I thought the psus were bad ( 2880 IBM ones )
But I got two brand new psus off eBay and its the same deal, first two green lights go on
Psu starts to get super hot BC fans wont activate

I've tried sp20s ants 🐜. Any ideas?

Hi, it will depend on the date you ordered the boards.
The very first batch had some trouble because the pins dimensions were out of specs, so the contact wasn't perfect on the signal to turn on the psu or the fans.
The batches after that have signal pins soldered systematically to avoid any trouble, even if the pins are now to specs.

You can probably see even without removing the white plate if the pin to turn on the PSU is soldered

the one under the "n" is usually visible from the outside.

the one in the square under the "H" turns the fans on.

Good catch

I was able to fix one of the breakout boards by resoldering the contact , now the PSU works so fuck me I have 2 extras of these PSUs and nothing for them to
power if you could have told me to check that bit on the breakout boards when I first had the issues could have saved me a bit of cash. I'll have to feebay the extra PSU's

The other breakout board seems to be toast probably would have to take it apart to figure out what's wrong with it but yeah its the breakout boards since the one I "Fixed" powers the fans on all the PSU's now even the used ones I got from you.

If you soldered both pins on the second breakout board the last thing that can fail is the switch.
There are two holes next to it that I use for testing purpose and can also be used for a remote switch. You can connect both holes with a paperclip to bypass the switch. Spacing is also correct to solder 2 pins and use a jumper.

I'll take a look at those two holds and

I didn't solder anything on the other one (not working one) , I looked at all the pins and they seem to make contact. The switch works though since the unit actually powers on , I'll send you a PM for another two breakout boards and worry about fixing this one later. I don't have anything for these units to power until I get my alcheminer fixed though.
