Hello, The PCM is part of the supply, so the entire power supply would have to be replaced.   Most likely you'd have to find a used/refurbished unit.  I don't believe you can still by these from Dell anymore.    What firmware is that array running?   Firmware might be very old.  Regards,  Don   
I've got an old PS4000 that's long out of warranty and I'm trying to decide whether or not to decommission it or to re-purpose it, but lately, I've been getting errors related to the power cooling module about once a week.  The error reads, "Power cooling module 0 is turned off or not receiving power."  When I log in and check the status of the device, it all shows OK.  I can't get any assistance from Dell Tech Support because it's out of warranty so I'm trying to figure out if there are any troubleshooting steps I can take to determine whether or not the power module needs to be replaced so I can get pricing and see if it's worth it to replace the module or scrap the whole thing.  Thanks in advance.
