Preparing for Installation
Before you begin installing your Cisco 811 and 813 routers, perform the following steps:
Step 1 
Order an ISDN BRI line from your telephone service provider. For more information, see the Cisco 800 Series Routers Software Configuration Guide.
Step 2 Be aware of Ethernet and ISDN cable distance limitations. For more information, see the "Maximum Cable Distances" section.
Step 3 Gather the Ethernet devices to be connected to the router: hub, server, workstation, or PC with 10- or 10/100-Mbps network interface card (NIC).
Step 4 If you have a Cisco 813 router and plan to connect a digital telephone, you must provide a data service unit (DSU) with two S/T interfaces and one U interface, an S/T cable that connects the router S/T port to the DSU, plus a telephone cable (usually provided with the device) to connect the telephone.
Step 5 If you have a Cisco 813 router, gather any device (such as an analog telephone, fax machine, or modem) that you plan to connect to the router. You must also provide the telephone cable (usually provided with the device) to connect each device.
Step 6 If you plan to configure the software using a terminal or PC connected to the router, provide the terminal or PC.
Caution If you are mounting the router on drywall, use three hollow-wall anchors to secure the three 1/8-in. (M3) screws. If the screws are not properly anchored, the strain of the network cable connections could pull the router from the wall. Use the drill bit size that is specified by the hollow-wall anchor manufacturer.
Safety
Before installing the router, read the following warnings:
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning Read the installation instructions before you connect the system to its power source.
Warning Before working on a system that has a standby/off switch, turn the power to standby and unplug the power cord.
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 weld the metal object to the terminals.
Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers.
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. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
Warning If the symbol of suitability with an overlaid cross (
) appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage your router
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 with the combination of synthetic fibers and dry atmosphere.
Always use the following ESD-prevention procedures when removing and replacing components:
Step 1 Connect the chassis to earth ground with a wire that you provide.
Step 2 Wear an ESD-preventive wrist strap that you provide, 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. Always follow the guidelines in the preceding section, "Safety."
Step 3 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.
Note This device is intended for use in residential and commercial environments only.
Caution Periodically check the resistance value of the antistatic strap; it should be between 1 and 10 megohms (Mohms).
Preventing Router Damage
Use the following guidelines when connecting devices to your router:
•Connect the color-coded cables supplied by Cisco to the color-coded ports on the back panel.
•If you must supply your own cable, see the "Cabling" section. If this section does not provide specifications for a particular cable, we strongly recommend ordering the cable from Cisco.
•If the symbol of suitability (
) appears above a port, you can connect the port directly to a public network that follows the European Union standards.
Warning If the symbol of suitability with an overlaid cross () appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage your router
