Chapter 3 Installing Modules and Cables in the Chassis
Connecting Power to the Router
Caution Ethernet management ports are primarily used as Telnet ports into the Cisco ASR 9001, and for booting
or accessing Cisco software images over a network to which an Ethernet port is directly connected. We
strongly caution you to consider the security implications of enabling routing functions on these ports.
Note The Ethernet interfaces on the RP are end-station devices only, not repeaters.
Use this procedure to connect an Ethernet cable to the RP RJ-45 Ethernet receptacle:
Step 1 Plug the cable directly into the RJ-45 receptacle.
Step 2 Connect the network end of your RJ-45 cable to a switch, hub, repeater, or other external equipment.

Connecting Power to the Router

Use one of these procedures to connect power to your router.
Connecting Power to an AC-Powered Router, page 3-18
Connecting Power to a DC-Powered Router, page 3-20
Caution A router must be operated with all its power modules installed at all times for electromagnetic
compatibility (EMC).

Connecting Power to an AC-Powered Router

Use this procedure to connect the AC power cords to the router.
Note Connect each AC power supply to a dedicated power source (branch circuit). Each AC-input
power supply operates at a nominal input level of 100 to 240 VAC and requires at least a 15 A
service for use in North America and Japan, or a 10 A service for international use. For more
information on AC power input levels, see the “Power Connection Guidelines” section on
page 1-12.
Step 1 Check that the power switch at the front of the chassis is set to the OFF position.
Step 2 Check that the circuit breaker assigned to the AC power source you are connecting is set to OFF.
Step 3 Connect the permanent ground connection (central office grounding system) to the NEBS grounding
location on the router chassis.
Note To ensure that power remains off while you are performing this procedure, turn the circuit breaker switch
in the off (0) position until you are ready to turn it on.
