Chapter 1 Introduction
Power Supply
The Cisco ASR 901 router uses two 3 pin connectors (part number 27-2030-01) for input to the power
supply. The terminal block is part of the accessory kit (part number 53-3085-01/53-3295-0), which ships
with the Cisco
ASR 901 router.
The ground wire connects to a 2-hole plug, which connects to the corresponding mounting point.
With the connector installed in the chassis, the pins are numbered as 1,2, and 3, respectively.
