    Delta DPS-450CB-1 A Redundant PSU

    I have two of these badged as Compaq spares for;
    Compaq Proliant ML530 ML570 G1 Server 450W Redundant Power Supply

    The datasheet can be found at;


    Being hotswap, can anyone help as to how to test one of these?
    They have spade connectors and I believe an I2C control block.

    Apparently (according to the datasheet), these require a min. load
    of 0.5A on the +3.3V, +12V and +5v rails.

    If I can figure out how the spades correspond to the rails, would
    it be safe(ish) to power the unit on and test the no load O/P
    readings with a m/meter?

    I really just require to establish if these are working.

    Of course, if I had thought about it, I should have grabbed
    the connector and loom from the server they were removed
    from to rustle up a quick test rig.

    Any suggestions?

    Thanks

    You can use regular light bulbs for loads I think.
    Will alligator clips work to connect?
    Don't forget to jumper Power_On to ground.

      Troubleshooting of redundant F750E-S0 Dell PowerEdge Server
      by omega
      Hello all,
      as a beginner electronics hobbyist, after a few years I would like to place another post on this Forum section, given that I did not succeed in finding any useful advice among the other posts.

      Over the last years, I have been using a PowerEdge Dell Server with two redundant PSUs, namely the 750W F750E-S0 ones (aka 06W2PW). Unfortunately, last summer one of them failed (perhaps owing to an overheating), and the server had for working to take into account the other one only. Of course I opened and tried to troubleshoot the failed PSU, but each cap I tested seemed to...
