Chapter 1 Introduction

Power Supply

LEDs

The Cisco ASR 901 chassis and interface modules contain LEDs to assist in troubleshooting. For more detailed description of the LEDs, see the “Reading the LEDs, page A-4.

Power Supply

The Cisco ASR 901 router is equipped with an internal -27/-72 volts Direct Current (VDC).

Safety Precautions

Observe the following general safety precautions and recommendations in planning the source power requirements for the Cisco ASR 901 router (for additional safety information, see the “Safety Guidelines” section on page 2-1:

•Check the power at your site before router installation (and periodically after installation) to ensure clean power (free of spikes and noise) is being received.

•Always disconnect the power source and unplug the power cable before working on the router.

•Install proper grounding for the site to avoid damage from lightning and power surges.

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions. Statement 1015

Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
