System Overview 37
PSU – 5U CRU
Power is provided by two 2,214W PSUs. The PSU voltage operating range is nominally 200V–240V
AC, and operates at 50–60 Hz input frequency. The dimetric rear orientation in Figure 42 shows the
PSU aligned for insertion into its slot located on the chassis rear panel.

NOTE: If any of the PSU LEDs are illuminated amber, a module fault condition or failure has
occurred.
Dual PSUs provide redundant power for the 5U system: if one PSU fails, the other keeps the system
running while you replace the faulty module. PSUs are hot-swappable. Replacement of a PSU can be
performed while the chassis is running, but the procedure must be completed within two minutes of
the removal of the defective module. Verify that you have a replacement PSU on hand before
removing the defective module.
