Note A Cisco XR 12406 Router operating from an AC power source can be converted
to operate from a DC power source, and vice versa. The conversion can be done
in the field, but the system must be powered down.
AC Power Subsystem
The AC power subsystem consists of the following system components:
• AC PDU (one)
• AC-input power supplies (one for nonredundant operation; two for redundant
operation)
Caution To ensure that the chassis configuration complies with the required power
budgets, use the on-line power calculator. Failure to properly verify the
configuration may result in an unpredictable state if one of the power units fails.
Contact your local sales representative for assistance.
AC PDU
Facility AC power connects to AC-powered the Cisco XR 12406 Router though
the AC PDU on the chassis rear panel (
