Chapter 2 Product Installation

2.1 Installation Requirements

Caution:

To avoid possible product damage or body injury, consider the

following issues.

z Maintain an indoor temperature of 0°C to 40°C (32°F to

104°F) and a humidity level of 10% to 90%.

z Keep the router far away from radio transmitting stations,

radar stations, and high-frequency devices. Use

electromagnetic shielding if necessary.

z Do not place the router on an unstable table or platform.

z Make sure that the rack/workbench has a good ventilation

system and is properly grounded.

z Wear an ESD-preventive wrist strap during installation,

making sure that it has good skin contact.

z Reserve adequate clearance at the air inlet and exhaust

ports for proper ventilation.

z For power supply, use a single-phase three-prong power

socket with an earth contact or use a universal PC power

socket, making sure that the earth contact is well connected

to the building ground.

z Make sure the correct voltage is used.

z Put a lightning arrester at the front end of the power input to

enhance its lightning protection. To this end, put a special

lightning arrester at the front end of signal cables that are led

outdoors.

z Do not open the chassis when the router is operating or

when electricity hazards are present to avoid electrical

shocks. Before you open the chassis, obtain the permission

of your sales agent.

z Correctly connect the interface cables.

z Do not hot swap any cable.

2.2 Installing the Router

You can place your router on a sturdy tabletop or workbench, or

mount it in a rack.

2.2.1 Placing the Router on a Tabletop/Workbench

When placing the router on a tabletop or workbench,

z Make sure that the tabletop or workbench is sturdy enough.

z Allow 10 cm (3.9 in.) of clearance around the chassis.

z Do not place a router on another.

2.2.2 Rack-Mounting the Router

AR 18-22-24 is designed according to the dimensions of the

standard 19-inch cabinet and can be installed in the rack.

Follow these steps to install the router (see

Figure 2-1):

Step 1: Check the grounding and stability of the rack. Use the

screws to fix the mounting ears at both sides near the front panel or

the rear panel of the router.

Step 2: Put the router in a rack tray. Depending on the actual

situation, slide the router along the chassis guides to an appropriate

place.

Step 3: Fasten the mounting ears with the recess screws to

secure the router in the rack horizontally and firmly. The specifications

of recess screws should satisfy the installation requirements and the

surface of the screws should be anti-rust.

2.3 Connecting the Ground Wire

Caution:

Properly connect the ground wire before connecting other cables and

shorten it as much as possible to prevent the router and the connected

device from getting damaged during periods of lightning activities.

The grounding screw of the chassis is located on the rear panel.

Connect this screw to the earth ground with a ground wire. The

grounding resistance must not be greater than 5 ohm.

2.4 Connecting the Power Cord

I. AC-input power supply

The required AC input voltage range: 100 VAC to 240 VAC, 50/60

Hz.

The AC-input power socket is illustrated in the following figure.

II. Recommended AC-input power socket

You are recommended to use a single-phase three-prong socket

with an earth contact, which must be properly grounded. The ground

of the building power system is often buried during the wiring

engineering. Make sure that the building ground is OK before

connecting the AC power cord.

III. Connecting the AC-input power cord

Step 1: Make sure that the grounding screw of the router has

been connected to the earth ground.

Step 2: Put the power switch of the router in OFF position.

Connect the output of the power supply to the power input on the rear

panel of the router, and then insert the input connector of the power

supply into an AC power outlet.

Step 3: Put the power switch of the router in ON position.

Step 4: Check that the Power LED on the front panel is ON. ON

means the power cord is connected correctly.

2.5 Connecting the Router to a Console

Terminal

I. Console cable

The console cable has an RJ-45 connector at one end and a DB9

(female) connector at the other end.

Figure 2-3 Console cable assembly

II. Connecting the console cable

Follow these steps to connect the router to a console terminal:

Step 1: Select a console terminal.

The console terminal can be either a standard ASCII terminal

with an RS-232 serial interface or more commonly, a PC.

Step 2: Connect the console cable.

Power off the router and the console terminal, and then connect

the RS-232 serial port on the console terminal to the console port on

the router using the console cable.

Verify the connection and power on the router. If everything is OK,

the startup information is displayed on the terminal screen. For details,

refer to

3.1.2 Powering On the Router.

2.6 Connecting the Router to LAN

I. Ethernet cable

A 10/100Base-TX Ethernet interface is usually connected to an

Ethernet using a category 5 twisted pair cable as shown in following

figure.

Figure 2-4 Ethernet cable assembly

Ethernet cables fit into two categories: straight-through and

crossover.

z Straight-through cable: The wires at both ends are crimped

in the same sequence in the RJ-45 connectors. The cable is

used for connecting different types of devices, such as a

terminal device (PC for example) or router to a Hub or LAN

switch.

z Crossover cable: The wires at both ends are crimped in

different sequence in the RJ-45 connectors. The cable is

used for connecting the same type of devices, such as a PC

to another PC or to a router.

Caution:

In preparing network cables, shielded cables are preferred for the

sake of electromagnetic compatibility.

II. Connecting the Ethernet cable

Caution:

Observe carefully the mark above the port before making connection

to make sure it is the right port.

The 10/100BASE-Tx interfaces on AR 18-22-24 support

auto-MDI/MDIX, so you can use either the straight-through cable or

crossover cable to connect a PC, router, HUB or LAN switch.

z Connect the cable to the Ethernet port on the router;

z Connect the other end of the cable to the peer device.
