Installing the Power Supply

The Cisco ASR 903 Router as a satellite shelf provides the choice of two different power supplies:
• DC power—19.2VDC to –72VDC
The DC power supply uses three-position terminal block-style connector with positive latching/securing and
labeled connections for +24/48V, GRD, –24/48V. The terminal block connector is of suitable size to carry
the appropriate AWG wire size to handle the input current of the power supply. No ON/OFF switch is provided.
• AC power—85 VAC to 264 VAC
The AC power supply has an IEC 320-type power receptacle and a 15-A service connector. You can use
standard right angle power cords with the AC power supply. The power supply includes a power cord retainer.
No ON/OFF switch is provided.
Each power supply provides a single primary input power connection. You can install dual power supplies
for redundancy.
