  Safety Recommendations
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. 
CautionFor 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
WarningIn 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
WarningDo 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.

Chapter 2      Preinstallation Requirements
  General Site Requirements
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.
WarningThe 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.)
Ta b l e 2-1 lists power requirements for the Cisco 1800 series fixed-configuration routers.
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 on page 2-5 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.

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 on page 2-3. 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

Mounting a Cisco 1800 Series Fixed-Configuration Router on a Wall
The Cisco 1800 series fixed-configuration routers have slots on the bottom of the chassis for mounting 
the unit on a wall or other vertical surface.
WarningThis unit is intended to be mounted on a wall. Please read the wall mounting instructions carefully 
before beginning installation. Failure to use the correct hardware or to follow the correct procedures 
could result in a hazardous situation to people and damage to the system. Statement 248
Ti pWhen choosing a location for wall-mounting the router, consider cable limitations and wall structure. 
Ti pIf your router has the optional wireless LAN feature, before you mount the router on a wall, connect the 
antennas to the back panel. It is difficult to attach the antennas after the router has been mounted to a 
wall.
To attach the router to a wall, use the following hardware:
 For attaching to a wall stud, use two number-10 wood screws (round- or pan-head) with number-10 
washers, or two number-10 washer-head screws. The screws must be long enough to penetrate at 
least 3/4 inch (20 millimeters) into the supporting wood or metal wall stud.
 For hollow-wall mounting, use two number-10 wall anchors with washers.
