Preventing Damage to the Router

General Safety Guidelines for Wireless Routers

Use the following guidelines for wireless routers:

•Do not touch or move the antenna while the unit is transmitting or receiving data.

•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, national codes, and safety directors of such environments.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur in the presence of synthetic fibers and dry atmosphere.

Always use the following ESD-prevention procedures when removing and replacing components:

Step 1 Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin contact.

Caution To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. Always follow the warnings and guidelines in this section.

Step 2 Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable attached.

If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the cable. This device is intended for use in residential and commercial environments only.

Caution Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm).

Preventing Damage to the Router

Follow these guidelines when connecting devices to your router:

•Connect the color-coded cables supplied by Cisco Systems to the color-coded ports on the front panel.

•If you must supply your own cable, see the cabling specifications in Appendix A, “Specifications.” If this appendix does not provide specifications for a particular cable, we strongly recommend that you order the cable from Cisco Systems.
