Before you begin installing your Cisco 811 and 813 routers, perform the following steps:
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.
Step 7 If you plan to mount your router on a wall or vertical surface, you need to provide two number-six, 3/4-in. (M3.5 x 20 mm) screws. However, if the wall on which you mount your router is drywall, you instead need to provide two hollow wall-anchors (1/8 in. with 5/16-in. drill bit or M3 with 8-mm drill bit) to secure the screws.
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 |
Always use the following ESD-prevention procedures when removing and replacing components:
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). |
Use the following guidelines when connecting devices to your router:
) appears above a port, you can connect the port directly to a public network that follows the European Union standards.
This section contains information about environmental, power, and cabling requirements.
Table 2-1 lists the environmental requirements for the operation of the Cisco 811 and 813 routers:

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
This section contains specifications for the following:
Table 2-3 lists the specifications for straight-through and crossover Ethernet cables. Refer to the glossary for definitions of straight-through and crossover cables.
| Type | Category | Shielding |
|---|---|---|
10BaseT | Category 3 or 5 | Shielded twisted-pair (STP) |
10BaseT | --- | Unshielded twisted-pair (UTP) |
Table 2-4 shows the maximum distances of Ethernet, ISDN, and telephone cables that you can use:
| Cable | Maximum Distance |
|---|---|
328 ft (100 m) | |
ISDN S/T and U cables | 32.8 ft (10 m) |
Telephone cable | 500 ft (152 m) |
Figure 2-1 shows the items included with your router. If any of the items is missing or damaged, contact your customer service representative.
