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.

2
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

3
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)

4
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.

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.”

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.
