Preparing for installation
Safety recommendations
W
ARNING!
Before installation and operation, read all of the safety instructions in the
Compliance and Safety
Guide
supplied with your router.
General safety recommendations follow:
•Turn off all power and remove all power cables before opening the chassis.
•Unplug all power and external cables before moving the chassis.
•Before installation, locate the emergency power switch so that you can shut off power immediately if
necessary.
•Always wear an ESD-preventive wrist strap when installing the device.
•Do not stare into an open optical interface. The light can cause permanent eye damage.
•Use a good grounding system. This is essential for reliable operation.
•Confirm that the resistance between the chassis and the ground is less than 1 ohm.
Site requirements
The router can only be used indoors.
This section provides information about temperature, humidity, cleanness, and air quality requirements, as

Installing the router on a workbench
To install the router on a workbench, as shown in Figure 14:
1. Make sure the workbench is clean, stable, and properly grounded.
2. Place the router upside down on the workbench and attach the rubber feet to the four round holes
in the chassis bottom.

the router on a wall, position the router so the network interfaces face down (toward
the floor), and the sides with ventilation openings are perpendicular to the ground, as shown in Figure
15.
To mount the router on a wall, as shown in 4:
1. Mark the locations of the two mounting holes on the wall, 180 mm (7.09 in) apart. The holes must
be level (on the same horizontal line.)
2. Drill two holes in the wall.
3. Following the marks, drill the two holes at least 22 mm (0.87 in) deep. Verify that the holes are
level.
4. Insert an anchor into each hole so it is flush with the wall surface.
5. Drive a screw into each anchor, keeping the screw heads protruding at least 1.5 mm (0.06 in)
from the wall.
6. Hang the router on the screws.

Grounding the router
W
ARNING!
Connecting the router grounding cable correctly is crucial for protecting the router from lightning and
EMI.
The grounding resistance should be less than 5 ohms.
You can ground the router in one of the following ways, depending on the grounding conditions at the
installation site:

14
•Ground the router to a properly-grounded grounding strip.
•Ground the router to a grounding conductor buried in the earth.
Grounding the router with a grounding strip
To connect the grounding cable:
1. Remove the grounding screw from the rear panel of the router chassis.
2. Put the OT terminal of the supplied grounding cable on the grounding screw, as shown in Figure
16.
3. Use a screwdriver to fasten the grounding screw, with the grounding cable OT terminal attached,
to the grounding screw hole.
4. Attach the other end of the grounding cable to the grounding strip, as shown in Figure 17.

Grounding the router to a buried grounding conductor
If the installation site has no grounding strips but offers the option of grounding to earth, hammer a 0.5 m
(1.64 ft) or longer angle iron or steel tube into the earth to serve as a grounding conductor, as shown
in Figure 18.

Installing an antenna
CAUTION:
Do not touch the antenna top, especially after the antenna is connected with the grounding contact.
Otherwise ESD may damage the router.
To ensure signal quality, use antennae supplied with the router.
To install an antenna:
1. Adjust the angle of the antenna to 180º.
2. Attach the antenna to the router, as shown in Figure 19. Avoid over-tightening.
The antenna must be vertical to the ground or ceiling to achieve the optimal coverage.
Figure 19 Installing an antenna

Connecting interface cables
Before powering on the router, connect the router's interface cables.
Connecting an Ethernet cable
The router includes WAN and LAN Ethernet ports.
For a 10/100 Mbps copper Ethernet port that supports MDI/MDIX autosensing, you can use either a
straight-through cable or a crossover cable to connect the port to a hub or LAN switch.
To connect an Ethernet cable:
1. Connect one end of the cable to an Ethernet port on the router, as shown in Figure 20 and Figure
21.
2. Connect the other end of the cable to the peer device.
