Overview
AC Power Entry Modules
The Cisco uBR10012 router is shipped with two AC power entry modules (AC PEMs) that provide
power supply to the system. One AC PEM module is sufficient to provide power for a fully configured
chassis. However, if one AC PEM module fails, the other AC PEM module automatically begins
providing power to the entire chassis, without impacting the system operation.
The AC PEM modules use a standard 200–240 VAC (50 or 60 Hz) input power obtained through power
receptacles on the front panel of each PEM. The two AC PEMs convert the AC power to provide filtered,
redundant, and load shared DC power to the Cisco uBR10012 chassis. The AC PEM modules can be
identified by their product part numbers.
The AC PEM modules supported on the Cisco uBR10012 chassis are:
•
•
