C H A P T E R 2 Installation This chapter provides information on the following topics: • Preparing for Installation • Preventing Damage to the Router • Installing the Router • Verifying Router Operation • Mounting the Router • Connecting to a Website • What to Do If You Cannot Connect to a Website Preparing for Installation This section provides information on safety, mounting of the router, and unpacking the router box.
Chapter 2 Installation Preparing for Installation Warnings Before installing the router, read the following warnings: Warning Read the installation instructions before you connect the system to its power source. Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Warning No operator serviceable parts inside. Refer servicing to qualified personnel.
Chapter 2 Installation Preparing for Installation Warning The ports labeled "10BaseT", 100BaseTX", and "10/100" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Avoid connecting these circuits to telephone network voltage (TNV) circuits. Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits.
Chapter 2 Installation Preparing for Installation Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call.
Chapter 2 Installation Preparing for Installation 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 (Mohms). Unpacking the Box Table 2-1 lists the items that come with your router.
Chapter 2 Installation Preventing Damage to the Router Step 4 If you plan to use the cable-lock feature, provide a Kensington or equivalent locking cable. 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 back panel. • If you must supply your own cable, see Appendix A for cabling specifications.
