Statement 1030
This section provides the procedures for connecting AC-input and –48 VDC input power to your
Cisco ASR 1004 Router.
The –48 VDC power supply for the Cisco ASR 1006, ASR 1004, and ASR 1002 routers operate at
individual specifications. Table 7-2 shows the common input ranges and circuit breaker requirements.
Note All Cisco ASR 1000 Series Router AC power supplies must be connected to a branch circuit that does
not exceed 20 A.
Note Detailed instructions for removing and replacing the Cisco ASR 1000 Series AC and DC power supplies
are in Chapter 13, “Removing and Replacing FRUs from the Cisco ASR 1000 Series Routers.”
Connecting AC Input Power to Cisco ASR 1004 Router
Follow these steps to connect an AC input power supply to the Cisco 1004 chassis:
Step 1 Insert an AC power supply in power supply slot 0 or power supply slot 1 until it is fully seated.
Step 2 Tighten the captive screws.
Step 3 Insert the AC power cable into the power inlet.
Step 4 Plug the power supply cable into the power source.

Series Router DC
Power Supply System Input Rating (Amps) Circuit Breaker Amps AWG # Wire
Minimum Maximum Minimum Maximum
Cisco ASR 1006 40 Always 50 Always AWG #6 wire
Cisco ASR 1004 24 30 40 10 8
Cisco ASR 1002 16 20 30 12 10
For example, the Cisco ASR 1002 Router –48 VDC power supply, with 16 Amp input rating must use an AWG #12 gauge wire for a 20 A circuit breaker
and an AWG #10 gauge wire for a 30 A circuit breaker.
