2,000W PSU
The 2,000W PSU voltage operating range is nominally 200V-240VAC, and the input frequency operating range is 50-60
Hz. The dimetric rear orientation in
shows the PSU aligned for insertion into either PSU slot located on the
enclosure rear panel. Also remove the crossbar before inserting or removing a PSU.

Multiple power supply unit modules
The 4U storage system includes two hot-swappable PSUs that provide redundant power control for the system so that if
one module fails, the other maintains the power and enclosure operation is not affected while the faulty PSU is being
replaced. See FRU Replacement Time Limit (
) for maximum allowable time to replace FRUs. See section
“Replacing a PSU module” (page 79)
for replacement instructions. Note the slide-rail crossbar needs to be removed to
get access to PSUs.
IMPORTANT:
Operation of the enclosure with any modules missing will disrupt the airflow, and the drives will not
receive sufficient cooling. It is essential that all slots are fitted with PSUs prior to powering on the enclosure.
