Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning Read the installation instructions before connecting the system to the power source. Statement 1004

Follow these guidelines when working on equipment powered by electricity:

Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly turn off the power.

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

Do not work alone if hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Never open the enclosure of the router's internal power supply.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn off power to the device.

If possible, send another person to get medical aid. Otherwise, assess the victim's condition and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but still connected to telephone wiring or other network cabling:

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for it.

Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface.

Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur if electronic printed circuit cards are improperly handled, and can cause complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing modules:

Ensure that the router 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 channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

If no wrist strap is available, ground yourself by touching a metal part of the chassis.

Caution For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should be between 1 and 10 megohms (Mohm).

Additional Warnings for Wireless Routers

Warning In order to comply with FCC radio frequency (RF) exposure limits, antennas should be located at a minimum of 7.9 inches (20 cm) or more from the body of all persons. Statement 332

Warning Do not operate your wireless network device near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 245B

General Safety Guidelines for Wireless Routers

The following are guidelines for the wireless router models:

Do not touch or move antenna(s) while the unit is transmitting or receiving.

Do not hold any component containing a radio so that the antenna is very close to or touching any exposed parts of the body, especially the face or eyes, while transmitting.

The use of wireless devices in hazardous locations is limited to the constraints posed by the local codes, the national codes, and the safety directors of such environments.

General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before you begin the installation. If you experience shutdowns or unusually high error rates with your existing equipment, the information in this section can help you isolate the cause of failures and prevent future problems.

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 for connection to TN and IT power systems. Statement 1007

The AC power supply includes a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates the correct voltage, frequency [AC-powered systems only], current draw, and power dissipation for the unit.)

Site Environment

The Cisco 1800 series fixed-configuration router can be placed on a desktop, installed in a rack, or mounted on a wall or other vertical surface. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Having equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both the front panel and the back panel of the router. When facing the router front-bezel, airflow is from left to right,

When you plan your site layout and equipment locations, keep in mind the precautions listed in the "Site Configuration" section to help prevent equipment failures and reduce the possibility of environmentally caused shutdowns. If you are experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Wireless LAN Considerations

The type of antenna used with your wireless router and its location greatly impact the quality of wireless connections to the router. Cisco 1800 series fixed-configuration routers are compatible with three different antenna types—swivel-mount dipole antennas that mounts on the back panel of the router, a wall-mount antenna, and a ceiling-mount antenna.

For more information about antenna coverage and optimal usage, see the following documents:

Cisco Multiband Swivel-Mount Dipole Antenna

Cisco Multiband Diversity Omnidirectional Ceiling-Mount Antenna

Cisco Multiband Wall-Mount, Corner-Mount, or Mast-Mount Antenna

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:

Ensure adequate air circulation in the room where your router operates. Electrical equipment generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.

To avoid damaging equipment, always follow the ESD-prevention procedures described in the "Preventing Electrostatic Discharge Damage" section. Damage from static discharge can cause immediate or intermittent equipment failure.

Ensure that the chassis cover and module back panels are secure. All empty network module slots, interface card slots, and power supply bays must have filler panels installed. The chassis is designed to allow cooling air to flow within it through specially designed cooling slots. A chassis with uncovered openings permits air leaks, which may interrupt and reduce the flow of air across internal components.

Installation Checklist

The sample installation checklist lists items and procedures for installing a new router. Make a copy of this checklist and record the information in each column as you complete each task. Include a copy of the checklist for each router in your Site Log (described in the "Creating a Site Log" section).
