Cisco uBR10012 Universal Broadband Router Modules

DC Power Entry Modules

The Cisco uBR10012 router is shipped with two DC power entry modules (DC PEMs) that provide
power to the system. One DC PEM can provide sufficient power for a fully configured chassis. However,
if one DC PEM fails, the other automatically begins providing power to the entire chassis, without
impacting the system operation.
The two DC PEMs provide filtered, redundant, and load shared DC power to the
Cisco uBR10012 chassis. The DC PEM modules can be identified by their product part numbers.
The DC PEM modules supported on the Cisco uBR10012 chassis are:
