Hello,  Yes this is customer replaceable unit, which is hot swappable. But important note, you need to insert new power supply within 2 minutes after removing the old one's - to prevent overheating of DAE.  Regards, Pavel Goncharov
I have a CX4-240 and one of the DAE's is reporting a fault with it's power supply.  Bus 0 Enclosure 1 : Faulted Bus 0 Enclosure 1 Power B : Faulted - Resume Faulted Bus 0 Enclosure 1 : Resume fault  Are these hot swappable or do I need to power off the array to swap it out?
