Cisco 2000 Series Hardware Installation

Following is the information required to install the router chassis.

About This Guide

Follow this procedural path to install your router:

1Install the router hardware using the procedures described in this publication.

2After the hardware is installed, refer the Router Products Getting Started Guide or

to the appropriate software publication to conﬁgure the router.

3Refer to the “Reference” section in this publication for cabling and basic

troubleshooting information.

Installation

This section guides you through the installation of the router and includes information

on safety, inspecting the system, preventing electrostatic discharge (ESD) damage,

tools and parts required, rack mounting, wall mounting, and making external cable

connections.

Note If you have questions about agency approvals, basic troubleshooting, system

speciﬁcations, or speciﬁc cable pinout information, review the information in the

section “Reference” on page 9.

Safety Recommendations

Follow these guidelines to ensure general safety:

•Keep the router area clear and dust-free during and after installation.

•Put the removed router cover in a safe place.

•Keep tools away from walk areas where you and others could trip over them.

•Do not wear loose clothing that could get caught in the router chassis. Fasten your

tie or scarf and sleeves.

•Wear safety glasses when working under any conditions that might be hazardous to

your eyes.

•Do not perform any action that creates a potential hazard to people or makes the

equipment unsafe.

Installation

Warning Before working on equipment that is connected to power lines,

remove jewelry (including rings, necklaces, and watches). Metal objects will

heat up when connected to power and ground and can cause serious burns or

weld the metal object to the terminals.

•Locate the emergency power-off switch in the room in which you are working.

Then, if an electrical accident occurs, you can act quickly to shut the power off.

•Before working on the system, turn off the power and unplug the power cord.

•Disconnect all power before doing the following:

—Installing or removing a router

—Working near power supplies

—Performing a software upgrade

•Do not work alone when potentially hazardous conditions exist.

•Never assume that power has been disconnected from a circuit. Always check.

•Look carefully for possible hazards in your work area, such as moist ﬂoors,

ungrounded power extension cables, and missing safety grounds.

•If an electrical accident occurs, proceed as follows:

—Use caution; do not become a victim yourself.

—Turn off power to the system.

—If possible, send another person to get medical aid. Otherwise, assess the

condition of the victim and then call for help.

—Determine if the person needs rescue breathing or external cardiac

compressions; then take appropriate action.

Inspecting the System

Do not unpack the router until you are prepared to install it. If the ﬁnal installation site

will not be ready for some time, keep the router in the shipping container to prevent

accidental damage. When you have determined where you want the router installed,

proceed with the unpacking. The router, cables, publications, and any optional

equipment you ordered might be shipped in more than one container. When you

unpack each shipping container, check the packing list to ensure that you received all

of the following items:

•Router

•6-foot (1.8-meter) power cord

Installation

•Optional equipment (which might include network connection cables)

•A warranty card, a service and support card, and optional companion publications

as speciﬁed by your order

Inspect all items for shipping damage. If anything appears damaged, or if you

encounter problems when installing or conﬁguring your system, contact a service

representative.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It

occurs when electronic printed circuit cards are improperly handled and can result in

complete or intermittent failures. Always follow ESD prevention procedures when

removing and replacing cards. Ensure that the router chassis is electrically connected

to earth ground. Wear an ESD wrist strap, ensuring that it makes good skin contact.

Connect the clip to an unpainted chassis frame surface to safely channel unwanted

ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist

strap and cord must operate effectively. If no wrist strap is available, ground yourself

by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic

strap, which should be within the range of 1 and 10 Mohms.

Tools and Parts Required

Following are the tools and parts required to install the router:

•Screwdrivers:

—No. 1 Phillips

—Small, 3/16" (0.476 cm), and medium, 1/4" (0.625 cm), ﬂat-blade

•ESD-preventive wrist strap

•Optional rack-mount/wall-mount kit (with documentation)

•One interface cable for each interface you require

In addition, you might need the following additional external equipment:

•Rack- and wall-mount brackets, fasteners, and instructions

•Channel service unit/digital service unit (CSU/DSU) for the serial interfaces

•Ethernet transceiver

•Token Ring media attachment unit (MAU)

Installation

•Modem for remote conﬁguration (if required)

•Console terminal (conﬁgured for 9600 baud, 8 data bits, no parity, and 2 stop bits)

if future reconﬁguration is desired

Information on Mounting the Router on a Rack or Wall

Rack and wall mounting procedures are described in a separate publication included

with the optional rack mount kit. If you intend to rack mount the router, do so before

making the external connections.

Cisco Systems declaration of operating conditions:

The Cisco 2000 is designed to meet the requirements of NET1 and NET2.

Warnings

Interconnection directly, or by way of other apparatus, of ports marked:

“Safety Warning — See instructions for use”

with ports marked or not so marked may produce hazardous conditions on the network

and that advice should be obtained from a competent engineer before such a

connection is made.

The ports marked “Ethernet,” “Token Ring,” “Console,” and “AUX” have a safety

warning applied to them as follows:

“These ports do not provide isolation sufﬁcient to satisfy the requirement of BS6301;

apparatus connected to these ports should either have been approved to BS6301 or

have previously been evaluated against British Telecommunications plc (Post Ofﬁce)

Technical Guides 2 or 26 and given permission to attach; any that other usage will

invalidate any approval given to this apparatus.”

Connection of Power Supply. The Cisco 2000 is intended for use when supplied with

power from a supply providing 220-240 VAC, 50/60 Hz up to 5 Amps.

Other usage will invalidate any approval given to this apparatus if as a result it ceases

to comply with BS6301: 1989.

Installation

What to Do after the Router Hardware Is Installed

After the router hardware is installed, the system is ready to be powered on and

conﬁgured. For software conﬁguration information, refer to the following

publications:

•Router Products Getting Started Guide, Router Products Conﬁguration Guide and

Router Products Command Summary

•Cisco 2000 Quick-Start Guide (as needed)

•Troubleshooting Internetworking Systems (as needed)

To order these or additional associated publications, refer to the Service and Support

card that accompanied your router.

Reference

This section includes the following reference information:

•Troubleshooting information

•System speciﬁcations

•Cable pinouts

Note For additional information on the Cisco 2000 router, refer to the Cisco 2000

Quick-Start Guide. For information on installing the router hardware, refer to the

section “Installation” on page 1 of this publication.

Troubleshooting

The key to problem solving in this system is to try to isolate the problem to a speciﬁc

subsystem. By comparing what the system is doing to what it should be doing, the task

of isolating a problem is greatly simpliﬁed.

Check the following items to help isolate the problem:

•With the power switch on and system LEDs on, does the fan operate? If no, suspect

the fan or the 12-volt (V) power supply.

•Does the system shut down after being on a short time?

—Suspect a thermal-induced shutdown.

—Ensure that the chassis intake and exhaust vents are clear.

—Suspect a power supply failure.

•System does not boot up, but System OK LED is on: suspect the 12V power supply.

•System partially boots, but System OK LED is not on: suspect a 5V power supply

failure.

The System OK LED should be on after the system initializes correctly. (See Figure 1.)

Note If an interface is extremely busy, the corresponding LED will be on all the time.
