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.

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):

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.
