way that the power connections reside facing inside the rack when viewed from the front. This allows
the DC output terminals of the external AC-input power shelf to be on the same side as the DC-input
terminals of the Cisco uBR10012 chassis.
The Lineage AC-DC power shelf has two DC power sources, four AC-input power supply sources, and
J1 and J2 connectors. Each AC-input power supply module is automatically powered on when it is
plugged into the wall socket. (See
Figure 1-6)

Lineage AC-DC Power Shelf - Front and Rear View
All cable connections for AC-input power, DC-output power, and status signals are made from the rear
of the power shelf. Each AC power supply module has an individual AC facility cord attachment. All
four AC-input cords must be attached to the facility for all four AC power modules to function. Two
DC-interconnect cables provide DC-output power to the DC PEM (UBR10-PWR-DC=) modules on the
Cisco uBR10012 chassis. (See
Figure 1-7)

Note
The AC-input power cables, DC-output power cables, and alarm monitor cable are supplied along with
Lineage. We recommend that you use these cables for cabling the shelf to the Cisco uBR10012 router.
