Safety

This section contains information on warnings associated with using your router and on

electrostatic discharge (ESD).

Warnings

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.

Safety

Cisco 805 Router Hardware Installation Guide

2-2

Warning Before working on a system that has a standby/on 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 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.

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.

Figure 2-1 shows the Cisco 805 router ports that include SELV circuits. For a definition of

SELV and TNV, see “Terms and Acronyms” in “About this Guide.”

ESD

Figure 2-1 SELV Circuit Ports

ESD

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 guidelines when removing and replacing

components:

•Connect the chassis to earth ground with a wire that you provide.

•Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin

contact.

•Do not touch any exposed contact pins or connector shells of uncabled router ports.

•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, which

should be between 1 and 10 megohms (Mohms).

Required Equipment

You need to provide the following equipment:

•The hub, server, workstation, or PC that you plan to connect to the Ethernet port. The

server, workstation, or PC must have a 10- or 10/100-Mbps network interface card

(NIC).

•The asynchronous modem or channel service unit/data service unit (CSU/DSU) that you

plan to connect to the serial port.

•The serial cable that connects the router to the serial device. For information on

selecting and ordering the serial cable, refer to Appendix A, “Selecting a Serial Cable.”

•The terminal or PC with which you plan to configure the software or troubleshoot the

router.

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.

Unpacking the Box

The items that come with your router are listed below. All these items are in the accessory

kit that is inside the box that your router came in. If any of the items is missing or damaged,

contact your customer service representative.

•Power cord (black)

•Desktop power supply

•Console cable (light blue)

•DB-9-to-RJ-45 adapter for use with light blue console cable

•DB-25-to-RJ-45 adapter for use with light blue console cable

•Ethernet cable (yellow)

•Product documentation

Note A serial cable does not ship with the router. For information on selecting and

ordering the serial cable, refer to Appendix A, “Selecting a Serial Cable.”

Installing the Router

To install the router, perform the following tasks in the following order:

1Connect an Ethernet device.

2Connect a serial device.

3Connect a terminal or PC (for software configuration or router troubleshooting).

4Connect the power supply.

5Mount the router.

6Verify the router installation.

Connecting an Ethernet Device

You can connect the following devices to the Ethernet port:

•A hub

•A server, PC, or workstation with a 10- or 10/100-Mbps NIC

Table 2-1 lists the Ethernet devices you can connect to the router with the yellow Ethernet

cable and the appropriate settings of the router HUB/NO HUB button and the hub

equivalent of the HUB/NO HUB button. The default setting of the router HUB/NO HUB

button is HUB (in).

Connecting a Hub

Before connecting a hub, refer to Table 2-1 to determine how to set the router

HUB/NO HUB button and the hub equivalent of the HUB/NO HUB button if applicable.

Follow the steps in Figure 2-2 to connect a hub.

Connecting a Serial Device

You can connect any one of several serial devices to the router serial port. For more

information, see the “DTE or DCE” section in Appendix A, “Selecting a Serial Cable.”

Table 2-2 describes the devices most commonly connected to the router serial port and how

these devices are used.

Note A serial cable does not ship with the router. For information on selecting and

ordering the serial cable, refer to Appendix A, “Selecting a Serial Cable.”

Follow the steps in Figure 2-4 to connect a modem or CSU/DSU.

Caution The Cisco 805 router does not support the Australian IUT requirement,

which specifies that the router must communicate for 1/2 hour after a power

failure. If a power failure occurs, the Cisco 805 router stops communicating with

other devices.
