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 -24/-60 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

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.

Environmental Monitoring Temperature Sensor

You can use connector A or B or both.

Environmental Monitoring Temperature Sensor

The Cisco ASR 901 router has a temperature sensor to detect overtemperature conditions inside the

chassis. The overtemperature detection trips at 70°C. This condition is reported to the processor as an

interrupt, where the software generates the appropriate alarms. If the router reaches a temperature of

85°C, the power supply cycles itself to prevent the router from exceeding the maximum temperature

while being powered up.

Chapter 1 Introduction

Router Interface Numbering

Each network interface on a Cisco ASR 901 router is identified by a slot number and a port number,

explained in this sequence:

• Logical slot numbers starts from 0 for all built-in interfaces. The numbering format is Interface

type Slot number/Interface number.

Interface (port) numbers begin at logical 0 for each interface

type.

• Logical interface numbering for T1/E1 ports on the TDM interface module runs from 0/0 through

0/15. Ports are numbered bottom to top, left to right.

• Logical interface numbering for the built-in ethernet ports runs from g0/0 through g0/3, the combo

ports run from g0/4 to g0/7 and the SFP ports run from g0/8 through g0/11. The GE ports are

numbered bottom to top, left to right.
