Chapter 2 Cisco ASR 1000 Series Routers Component Overview

Cisco ASR 1000 Series Router Power Supplies

All Cisco ASR 1000 Series Router configurations support AC and DC power supply options. The

modular chassis configurations support the installation of two power supplies for redundancy. When an

external power supply fails or is removed, the other power supply provides power requirements for the

chassis.

You are required to always have two power supplies installed in the chassis to insure sufficient cooling

for the box. The system fans are inside the power supply unit and must spin for cooling. No Cisco

ASR 1000 Series Router will operate for more than two to three minutes without two power supplies

installed. Since all the system fans can be powered by one power supply, it is not required for the second

power supply unit to be powered on, but it must be installed. Cisco IOS software specifically looks for

two power supplies in the chassis and will automatically initiate a shutdown if only one power supply is

detected.
