Preparing for Installation

This section provides information on safety, mounting of the router, and
unpacking of the router box.

Safety

This section provides safety warnings and electrostatic and router damage
information for the Cisco 836 and Cisco SOHO 96 routers.

Cisco 836 Router and SOHO 96 Router Hardware Installation Guide

Only trained and qualified personnel should be allowed to install or replace this
equipment.

Read the installation instructions before you connect the system to its power
source.

Before working on a system that has a standby/off switch, turn off the power
switch to standby and unplug the power cord.

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

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.

During this procedure, wear grounding wrist straps to avoid ESD damage. Do
not directly touch the backplane during with your hand or any metal tool, or you
could shock yourself.

This equipment is not designed for making emergency telephony calls when the
power fails. Alternative arrangements should be made for access to emergency
services. Access to emergency services can be affected by any call-barring
function of this equipment.

To reduce the risk of fire, use only No.26 AWG or large telecommunication line
cord.

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.

Warning

Ths 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

Warning

Network hazardous voltages are present in the ISDN cable. If you detach the
ISDN cable, detach the end away from the router first to avoid possible electric
shock. Network hazardous voltages also are present on the system card in the
area of the ISDN port (RJ-45 connector), regardless of when power is turned off
(by pressing power switch to standby).

Ultimate disposal of this product should be handled according to all national
laws and regulations.

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 follow these steps to prevent ESD when you remove and replace
components:

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

skin contact.

2-30

Caution To properly guard against ESD damage and shocks, the wrist strap and cord must

operate effectively.

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.

Chapter 2 Installation

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 (Mohm).

Unpacking the Box

Table 2-1 lists the items that come with your router. 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.

Table 2-1 Router Box Contents

Power cord (black)

•

• Desktop power supply

• ADSL cable (lavender)

• Console cable, RJ-45-to-DB-9 (light blue)

• ISDN cable (orange)

• Ethernet cable (yellow)

• Product documentation

Preparing for Installation

78-15281-02

To prepare for installation, follow these steps:

Step 1 Remove yellow Ethernet cable, light blue console cable, and product

documentation from the accessory kit. Remove the desktop power supply, orange
ISDN S/T cable, the lavender ADSL cable, and the black power cord from the
box. Gather the Ethernet devices to be connected to the router: hub, server,
workstation, or PC.

Step 2 If you plan to connect an analog telephone or fax machine, gather these devices.

You must also provide the telephone cable to connect each device.

Preventing Damage to the Router

Step 3 If you plan to configure the software using a terminal or PC connected to the

router, provide the terminal or PC.

Note Unless otherwise specified, a lavender straight-through RJ-11to RJ-11 cable is

provided as the ADSL cable. The user can select one of two other cables
instead—a crossover RJ-11 to RJ-11 ADSL cable or a straight-through RJ-11 to
RJ- 45 ADSL cable. Each router is supplied with only one ADSL cable, which the
user selected during the ordering process.

Note The optional orange ISDN S/T cable used for connecting a Cisco 836 router’s

ISDN port to the ISDN service provider is for dial backup and remote
management. The Cisco SOHO 96 router needs this cable for remote
management. The user may order this optional cable additionally.

Chapter 2 Installation

Note There are six different power cords. Each was designed to meet the specifications

of the cable wall jack for a particular country. Each of the six power cords is
different from the others. The default cord shown in Figure 2-1 is European Union
standard specification.

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 cables, see Appendix A, “Specifications and

Cables,” for cable specifications. If this appendix does not provide

specifications for a particular cable, we strongly recommend that you order
the cable from Cisco Systems.

• 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.

Installing the Router

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 to your router.

Installing the Router

To install the router, you need to perform the following tasks in the following
order:

1. Connect the Ethernet devices to the router.

2. Connect the ADSL line.

3. Connect a terminal or PC to the configuration port of the router if you are

troubleshooting or configuring the router by using the command-line
interface (CLI).

4. Connect the router to the power source and turn on the router.

5. Verify the links, using the router LEDs.

Connecting Ethernet Devices

You can use a cable to connect an Ethernet devices to the router’s LAN port.

Connecting a Server, PC, or Workstation

Follow the steps given after Figure 2-1 to connect the router to a PC with an
Ethernet network interface card (NIC) installed, or to connect a server or
workstation to the router. (Figure 2-1 shows a Cisco 836 router, but it also applies
to a Cisco SOHO 96 router. The procedure applies to both the Cisco 836 router
and the Cisco SOHO 96 router.)

The Ethernet port on the Cisco 836 router and the Cisco SOHO 96 router supports
the auto-crossover function, whose autosensing ability allows the router to
connect automatically to the hub or PC.
