Notes:
1. A minimum of four -48VDC power feeds are required on PFU-A to provide non-redundant power to a chassis
and all its cards. Four additional power feeds are required on PFU-B for power redundancy (4+4 = 8).
2. Although the chassis may not draw 12.8 kW, a minimum of four 80-amp -48VDC feeds must be properly sized
and wired to PFU-A to assure that all chassis slots are powered and available for future expansion. All power
inputs on PFU-A must be connected to live power feeds to assure that all chassis card slots are energized.
inputs on PFU-A must be connected to live power feeds to assure that all chassis card slots are energized.
3. The type and number of cards installed in the ASR 5500 chassis determine the actual -48VDC power draw. See
Important:
The power source must be a UL/CSA listed device with a regulated output no greater than -60VDC.
Important:
The DC power Battery Return (BR) or positive terminal, must be grounded at the source end (power
feed or mains power end).
