    Hi, I have just acquired a 8 bay SAS enclosure from a Fujitsu TX300 S7, 8 SAS disks in 2x 5.25" bays, the front is as this one:
    Fujitsu HDD Expansion Box, 2.5" SAS - SATA C26361-K835-B276
    Thing is, the power is supplied by 2x 4 pin connectors that are a box configuration and all the wires going to the plug are grey.
    Does anyone know where I can find out which wire is which so I can either add molex connectors or where I can get adapters or if the molex to CPU adapters would work?
    I can supply a picture of the rear of the enclosure should anyone want to see it.
    Thanks in advance.

    those 2x 4pin connectors are definitly the same as general 4pin molex, electricly seen.

    the power cable you need is
    Y3952-V601

    did you look at the user and maintanance manual of 962 pages?

    Thanks for that, I didn't make myself very clear, I want to put the drive cage into a non-Fujitsu chassis, a home build if you wish.

    did you look at the backside of the backplane? isn't there any very very tiny text around the pins? can you dismantale the baackplane and have a look at the backside?

    partn number of the backplane is

    You only need to use the white "X6" 4-pin connector. The black one is used to optionally daisy-chain power other devices.

    The PSU only produces 12V and the power backplane looks very... plain. So my educated guess is that out of 4 pins - 2 would be the ground and 2 would be 12V. That would explain the wire colors as well. It should be trivial to track the voltages from the SAS connector pins for example.

    I've had both parts of the backplane under a magnifying glass, there isn't any small writing around the x6 connector, on either side.

    Looking through the magnifier, I can't see any of the tracks going to the SAS pins for power. Thanks for the tip though.

    I think I'll try a molex to 4pin CPU connector and see how it goes, I've not lost anything

    for safety, you first can try molex 4 pin eletric layout. if no succes, then maybe 4 pin eps electric layout. 4 pin eps has 2x 12volt lines. molex has 5v and 12v lines, so when using molex you couldn't toast your backplane

    I meant using multimeter in the Continuity Test mode.

    I'll dig out my multimeter and give it a go.

    Thank you for the information.
