The following figure shows the PSU.
Dual PSUs provide redundant power for the system. If one PSU fails, the other keeps the system running
while you replace the faulty module. The PSUs are hot-swappable. Replacement of a PSU can be
performed while the enclosure is running, but the procedure must be completed within 2 minutes of the
removal of the defective PSU. Ensure that you have a replacement PSU before you remove the defective
PSU.
The enclosure chassis is keyed to prevent PSUs from being inserted upside down.
The back of the PSU has a power switch, three status LEDs, and a socket for the power cord, as shown in
the following figure.
Power supply unit (2800 kW PSU)
