2.1 Installation Requirements
Caution:
To avoid possible product damage or body injury, consider the
following issues.
zMaintain an indoor temperature of 0°C to 40°C (32°F to
104°F) and a humidity level of 10% to 90%.
zKeep the router far away from radio transmitting stations,
radar stations, and high-frequency devices. Use
electromagnetic shielding if necessary.
zDo not place the router on an unstable table or platform.
zMake sure that the rack/workbench has a good ventilation
system and is properly grounded.
zWear an ESD-preventive wrist strap during installation,
making sure that it has good skin contact.
zReserve adequate clearance at the air inlet and exhaust
ports for proper ventilation.
zFor 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.

Installation Manual
H3C AR 18-22-24 Router Chapter 2 Product Installation

zMake sure the correct voltage is used.
zPut 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.
zDo 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.
zCorrectly connect the interface cables.
zDo 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,
zMake sure that the tabletop or workbench is sturdy enough.
zAllow 10 cm (3.9 in.) of clearance around the chassis.
zDo 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):

Installation Manual

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 requiredAC 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 theAC 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 hasan RJ-45 connector at one endand 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.
zStraight-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.
zCrossover 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.
zConnect the cable to the Ethernet port on the router;
zConnect the other end of the cable to the peer device.
