your eyes.
•Do not perform any action that creates a potential hazard to people or makes the
equipment unsafe.

2-2 Router Installation and Configuration Guide
Safety Recommendations
Warning Ultimate disposal of this product should be handled according to all national
laws and regulations. (To see translated versions of this warning, refer to the Regulatory
Compliance and Safety Information document that accompanied your router.)
Maintaining Safety with Electricity
Follow these guidelines when working on equipment powered by electricity.
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 can weld the metal object to the terminals.
(To see translated versions of this warning, refer to the Regulatory Compliance and Safety
Information document that accompanied your router.)
•Locate the emergency power OFF switch for the room in which you are working. Then,
if an electrical accident occurs, you can act quickly to turn OFF the power.
•Power OFF the router and unplug the power cord before doing the following:
—Installing or removing a chassis
—Working near power supplies
Warning Before working on a chassis or working near power supplies, unplug the power
cordon AC units; disconnect the poweratthecircuitbreakeronDCunits. (To see translated
versions of this warning, refer to the Regulatory Compliance and Safety Information
document that accompanied your router.)
Warning Do not touch the power supply when the power cord is connected. For systems
witha powerswitch,linevoltagesarepresentwithinthepowersupplyevenwhenthepower
switch is OFF and the power cord is connected. For systems without a power switch, line
voltages are present within the power supply when the power cord is connected. (To see
translated versions of this warning, refer to the Regulatory Compliance and Safety
Information document that accompanied your router.)

Preparing to Install the Router 2-3
Safety Recommendations
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
Warning Read the installation instructions before you connect the system to its power
source. (To see translated versions of this warning, refer to the Regulatory Compliance and
Safety Information document that accompanied your router.)
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded
power extension cables, frayed power cords, 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.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive
wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted
surface of the chassis frame 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.

2-4 Router Installation and Configuration Guide
General Site Requirements
Caution For safety, periodically check the resistance value of the antistatic strap, which
should be between 1 to 10 megohms (Mohms).
General Site Requirements
This section describes the requirements your site must meet for safe installation and
operation of your system. Ensure that your site is properly prepared before beginning
installation.
Site Environment
The router can be placed on a desktop or mounted in a rack or on a wall. The location of
the chassis and the layout of your equipment rack or wiring room are extremely important
for proper system operation. Equipment placed too close together, inadequate ventilation,
and inaccessible panels can cause system malfunctions and shutdowns, and can make
system maintenance difficult.
When planning your site layout and equipment locations, remember the precautions
described in the next section, “Preventive Site Configuration” to help avoid equipment
failures and reduce the possibility of environmentally caused shutdowns. If you are
experiencing shutdowns or unusually high errors with your existing equipment, these
precautions may help you isolate the cause of failures and prevent future problems.
Preventive Site Configuration
The following precautions will help you plan an acceptable operating environment for your
router and will help you avoid environmentally caused equipment failures.
•Electrical equipment generates heat. Ambient air temperature might not be adequate to
cool equipment to acceptable operating temperatures without adequate circulation.
Ensure that the room in which you operate your system has adequate air circulation.
•Always follow the ESD-prevention procedures described in the section “Preventing
Electrostatic Discharge Damage” earlier in this chapter to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment failure.

Preparing to Install the Router 2-5
General Site Requirements
•Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to
flow effectively within it. An open chassis allows air leaks, which may interrupt and
redirect the flow of cooling air from internal components.
Configuring Equipment Racks
The following information will help you plan an acceptable equipment rack configuration.
•Enclosed racks must have adequate ventilation. Ensure that the rack is not overly
congested because each unit generates heat. An enclosed rack should have louvered
sides and a fan to provide cooling air.
•When mounting a chassis in an open rack, ensure that the rack frame does not block the
intake or the exhaust ports. If the chassis is installed on slides, check the position of the
chassis when it is seated all the way into the rack.
•In an enclosed rack with a ventilation fan in the top, excessive heat generated by
equipment near the bottom of the rack can be drawn upward and into the intake ports of
the equipment above it in the rack. Ensure that you provide adequate ventilation for
equipment at the bottom of the rack.
•Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling
airthrough the chassis. The best placement of the bafflesdependsontheairflowpatterns
in the rack, which are found by experimenting with different arrangements.
Power Supply Considerations
Check the power at your site to ensure that you are receiving “clean” power (free of spikes
and noise). Install a power conditioner if necessary.
Warning The device is designed to work with TN power systems. (To see translated
versions of this warning, refer to the Regulatory Compliance and Safety Information
document that accompanied your router.)

2-6 Router Installation and Configuration Guide
Preparing to Connect to a Network
The router power supply includes the following features:
•Autoselects either 110V or 220V operation.
•Allunits include a 6-foot (1.8-meter)electrical powercord.(Alabelnear the powercord
indicates the correct voltage, frequency, current draw, and power dissipation for the
unit.)
Warning This product relies on the building’s installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.
(240 VAC, 10A international) is used on the phase conductors (all current-carrying
conductors).(Toseetranslatedversionsofthiswarning, refertotheRegulatoryCompliance
and Safety Information document that accompanied your router.)
Preparing to Connect to a Network
When setting up your router, consider distance limitations and potential electromagnetic
interference (EMI) as defined by the EIA.
Warning The Ethernet, Token Ring, serial, console, and auxiliary ports contain safety
extra-low voltage (SELV) circuits. BRI circuits are treated like telephone-network voltage
(TNV) circuits. Avoid connecting SELV circuits to TNV circuits. (To see translated
versions of this warning, refer to the Regulatory Compliance and Safety Information
document that accompanied your router.)
