Mounting the Access Point on a Pole

When installing an access point on a vertical pole, mast, or a streetlight pole, you should use the optional
Cisco pole mount kit. The kit supports metal, wood, or fiberglass poles from 2 to 16 inches in diameter.

Assembling the Pole Clamp Bracket and the Mounting Bracket

When installing an access point on a pole, mast, or a streetlight, you should use the optional Cisco pole
mount kit. The kit supports metal, wood, or fiberglass poles from 2 to 16 inches in diameter.

The pole mount kit contains several parts that you must assembled prior to mounting on a pole. First you
need to assemble two strap brackets on the pole clamp bracket that are positioned for the pole diameter

To assemble the pole clamp bracket, perform these steps:

Step 1 Position the strap brackets on the pole clamp bracket for the pole diameter you are using and secure each

strap bracket with two M8 x16 bolts (with lock washers) (see Figure 2-10). Tighten the bolts to
13 to 15 ft lbs (17.6 to 20.3 Nm).

from falling off.

The access point can be installed where power is available, without the need for a wired LAN
connection. The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path
Protocol (AWPP). AWPP enables a remote access point to dynamically optimize the best route to the
wired LAN network using another access point.

The LAP1522 model uses the 5-GHz radio for the Mesh backhaul Mesh connections. The 2.4-GHz radio
is used for local wireless client access. The LAP1521 model uses the 2.4-GHz radio for both Mesh
backhaul and local wireless client access.

To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands
around the pole to support the access point. This process requires extra tools and material not provided
in the pole mount kit (see

Table 2-3).

To mount the access point onto a vertical pole or streetlight pole, follow these steps:

Step 1 Select a mounting location on the pole to mount the access point. You can attach the access point to any

pole from 2 to 16 in. (5.1 to 40.6 cm) in diameter.

Note If you will be using a streetlight power tap adapter, position the access point within 3 ft (1 m) of

the outdoor light control.

Step 2 For poles larger than 3.5 in. (8.9 cm), mount the pole clamp bracket assembly to a pole (see Figure 2-11)

using two metal straps. Following the instructions provided with the hand strap tool
(AIR-BAND-INST-TL=), loop each metal strap twice through the slots on the strap bracket.

2-24

Caution Do not place the metal straps in the large open area between the pole clamp bracket and the strap

brackets, because this does not properly secure the access point.

Step 3 For pole diameters of 3.5 in. (8.9 cm) or less, mount the pole clamp bracket assembly to a pole using

two metal straps looped through the space between the pole clamp bracket and the strap brackets (see

Figure 2-12) to provide maximum holding strength for extreme environments. Following the

instructions provided with the hand strap tool (AIR-BAND-INST-TL=), loop each metal strap twice.

Step 4 Position the pole clamp bracket on the pole as needed before tightening the metal bands.

Note When the metal bands are tightened to the full tension, the pole clamp bracket cannot be adjusted

unless the metal bands are cut or disassembled.

Step 5 Tighten the metal bands using the band strap tool (Cisco AIR-BAND-IT-TOOL=), following the

operating instructions in the box with the tool. Ensure the metal bands are as tight as possible.

Step 6 Place the mounting bracket onto the pole clamp bracket support bolt (see Figure 2-13).
Step 7 For vertical poles, position the mounting bracket as shown in Figure 2-13. For horizontal streetlight

poles, rotate the mounting bracket 90o from the position shown in Figure 2-13.

Step 8 Install four M8 x16 bolts (with flat and lock washers) into the bolt holes.

Cable Strand Mounting

When mounting the access point on a cable strand, you must use the optional strand mount kit. The kit
contains several parts that you should assemble before mounting on a cable strand. To install the access
point to a cable strand, you need to perform these operations:

• Attach cable clamps to the clamp bracket

• Attach the strand bracket to the access point

• Attach the clamp bracket to the fiber or cable strand

• Attach the strand bracket (with access point) to the clamp bracket

• Attach antennas

• Attach a ground wire

• Connect cables and power to the access point

Note The access point must be installed on a cable strand by a professional cable installer.

Chapter 2 Mounting Instructions

To mount the access point preform these steps:

Step 1 Install two cable clips, a flat washer, and a M8 flange nut on each clamp support bolt on the front of the

clamp bracket (see

Figure 2-16). You should only hand-tighten the nuts sufficiently to prevent them

from falling off.
