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 necessa ry.
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 wo rkbench,
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 instal l 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 ra nge: 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.
St ep 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.

Figure 2-3 Console cable assembly
II. Connecting the console cable
Follow these steps to connect the router to a console terminal:
St ep 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.
V erify the connection and powe r on the router. If everything is OK, the startup information is displayed on th e terminal screen. For details, refer to
3.1.2 Powering On the Router.
