Materials and Tools You Supply
You must supply some or all of these items to mount the router on a pole. The items you supply depends on the
installation procedure that you use.
Mounting Instructions
This section includes all the procedures required to mount the router on any supported pole type.
This section covers the following procedures:
Router Orientation, page 54

Install the Router onto the Mounting Bracket, page 62
Mounting the Router onto a Wall, page 66
Router Orientation
When mounting the router on a pole, ensure that:
The router is oriented with the chassis cabling openings pointing down so the router cables can be correctly
connected through the openings and so the router door opens correctly, as shown in Figure 35 on page 62.
The router is mounted with the hinged access cover facing out.

Figure 29 on page 57:
1. Select a mounting location on the pole and place the top and bottom pole clamp bracket (1) notches against the
pole.
2. Place one of the clamp brackets on the opposite side of the pole, aligning the clamp bracket holes with the top two
carriage bolt holes on the mounting plate.
3. Insert a carriage bolt (5) through each of the top two carriage bolt holes on the mounting plate and through the holes
in the clamp brackets.
4. Position the each bolt in the clamp so that the bolt is next to the pole, as shown in Figure 28 on page 56.
5. To place the bracket hardware on each carriage bolt (see Figure 28 on page 56):

Figure 30 Mounting Plate Installed on Pole with Steel Straps
Install the Mounting Plate—Through-Pole Mounting (Optional)
If the pole used in your installation is made of wood, you can optionally install the mounting plate using the procedure
described in this section. This is an alternate mounting method to the following two mounting methods, which can also
be used when mounting the router on a wood pole:
Install the Mounting Plate—Poles Up to 4.5 Inches in Diameter, page 55
Install the Mounting Plate—Poles Larger than 4.5 Inches in Diameter, page 57
Required Materials
Mounting plate included in Pole Mount Kit, page 50.
Hardware that you supply: 5/8-in. carriage bolt (length depends on the pole size in your installation), standard
washer, fender washer, nut (2 sets)
Tools that you supply: Drill, drill bit (for 5/8-in. through bolts), and 13-mm box-end socket wrench
To mount the router on a wood pole:
1. Place the mounting plate on the selected mounting location on the pole.
2. Mark the drilling locations on the pole through the clearance holes and remove the mounting plate.
3. Drill holes completely through the pole at the points you marked in Step 2.
4. Position the mounting plate over the drilled holes. Align the clearance holes on the mounting plate with the drilled
holes.
5. Place a standard washer against one of the clearance holes on the mounting plate, then feed the bolt through the
washer, clearance hole, and drilled hole. Push the bolt all the way through the pole. See Figure 27 on page 55.
