Installation Option
The Cisco Aironet 1552 Series Outdoor Mesh Access Point for Hazardous Locations are installed using the optional Pole Mount installation kit, which is used for pole or wall installations
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074
Access Point Mounting Orientation
When mounting an access point on a horizontal or vertical surface, you must ensure that the access point is oriented with the LED indicators pointing down (see Chapter 2, “Pole Mount Installation”. This positioning allows the LEDs to be visible to someone on the ground below the access point.
You must also ensure the access point is mounted with the hinged access cover facing out.
Note Omnidirectional antennas are vertically polarized and should be mounted vertically.
Mounting the Access Point on a Wall
The optional pole mount kit contains a mounting bracket for wall mounting. You can use the mounting bracket as a template to mark the positions of the mounting holes for your installation. You then install the mounting plate, and attach the access point when you are ready. Table 3-1 lists the material that you will need to provide in addition to the pole mount kit.

(17.6 to 20.3 Nm).
Step 7 When using the Cisco Aironet Dual-Band Omnidirectional Antennas, connect them to the access point as shown in Figure 3-2. Hand-tighten the antennas to the access point.
Step 8 Continue with the “Grounding the Access Point (all models)” section and the “Powering the Access Point” section.
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 assemble 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 you are using to mount the access point. Figure 3-3 illustrates the pole diameter indicators and bolt holes on the pole clamp bracket.
Figure 3-3 Pole Clamp Bracket Adjustment Hole Locations
To assemble the pole clamp bracket, follow 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 3-4). Tighten the bolts to 13 to 15 ft lbs (17.6 to 20.3 Nm).

Step 2 Screw the M8 nut onto the pole clamp bracket support bolt, and tighten just enough to prevent the bolt from falling off.
Step 3 Go to the “Pole Mounting” section.
Pole Mounting
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 1552 access point uses the 5 GHz radio for the Mesh backhaul and connections. The 2.4 GHz radio is used for 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 3-2 ).

---|---|---|
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 inch (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 inch (8.9 cm), mount the pole clamp bracket assembly to a pole (see Figure 3-5) using two metal straps. Following the instructions provided with the banding strap tool (BAND IT) (AIR-BAND-INST-TL=), loop each metal strap twice through the slots on the strap bracket.

Warning Explosion Hazard—The area must be known to be nonhazardous before installing, servicing, or replacing the unit. Statement 1082
Note Please refer to the Declarations of Conformity and Regulatory Information when the AIR-CAP1552H-Q-K9 (POE input configuration only) will be installed in an explosive area in Japan.
The access point can be powered by one of these methods:
Power-over-Ethernet (PoE)—56 VDC power injector (AIR-PWRINJ1500-2=)
Note In all cases above, the AC branch circuit powering the access point must be limited to no more than 20A from the over-protection device supplied by the user. This branch power protection must meet all local and national electrical codes.
The 1552 access point for hazardous locations can be connected to more than one power source. The access point detects the available power sources and switches to the preferred power source using the following priority:
Connecting a 1552H Series Power Injector
The power injector provides 56 VDC to the access point over the Ethernet cable and supports a total end-to-end Ethernet cable length of 100 m (328 ft) from the switch to the access point.
Note The power injector is not intended to be installed in a hazardous locations environment. If a PoE injector is required, it must be located in a non-hazardous location environment.
Note The 1552SA/SD and 1552WU do not support PoE In.
Note The Ethernet cable from the power injector to the access point (PoE In port) must be at least 10 ft (3.1 m) in length.
Note The PoE Out port is disabled when the access point is powered by the power injector.
When your access point is powered by an optional power injector, follow these steps to complete the installation:
Step 1 Before applying PoE to the access point, ensure that the access point is grounded (see the “Grounding the Access Point (all models)” section).
Step 2 Review Chapter 2, “Pole Mount Installation” to identify the components needed for the installation.
Note It is recommended to install the injector in its own IP67 enclosure such as a Hoffman box, since the PoE injector is not weather proof.
Step 3 Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Use only the 1500 power injector (AIR-PWRINJ1500-2=) for the access point. This power injector is designed to meet the power requirements of the access point and is a listed Class 2 limited power source (LPS).
Note The installer is responsible for ensuring that powering the access point from this type of power injector is allowed by local and/or national safety and telecommunications equipment standards.
Tip To forward bridge traffic, add a switch between the power injector and controller. Refer to the Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0 for more information.
Step 4 Ensure that the antennas are connected and that a ground is attached to the access point before you apply power to the access point.

Step 3 Remove the cover and set it aside.
Step 4 Route the AC power cable through the 1/2-NPT port.
Step 5 Use a wire stripper tool to remove the insulation from each wire. Remove only enough wire to provide a solid connection in the terminal block. The hot wires should have no bare wire exposed after the connection is made.
Step 6 Insert the ground wire into the provided ground lug and use a crimping tool to secure the connection.
Step 7 Install the ground lug and tighten the connection with a Phillips screwdriver. To prevent stripping the screw threads, do not overtighten.
Step 8 Insert each hot wire into the AC entry terminal block.
Step 9 Use a Phillips screwdriver to tighten the terminal block set screws to secure the wires in the terminal block.
Step 10 Verify that no bare wire is exposed. If wire is exposed, remove it from the terminal block, adjust the length, and reinstall.
Step 12 Reinstall the AC entry module top cover and tighten the captive screws. Do not overtighten.
Step 13 Close the access point hinged cover. See the “Closing the Access Point Hinged Cover” section for details.
Step 14 Install the Ethernet backhaul cable. See the next section for instructions.
Performing Maintenance
The access point requires minimal periodic or preventive maintenance as it has no moving parts, filters, lubricants, or mechanical contact components. However, when installed in a hazardous location, periodic inspections should be conducted in order to ensure that the access point is operating satisfactory. This section provides information about performing maintenance on an access point installed in a hazardous location.
Additional maintenance information can be found in Chapter 4, “Troubleshooting” and the Troubleshooting a Mesh Network Guide. The troubleshooting document is available at cisco.com at the following URL:

Warning Do not disconnect connections to this equipment unless power has been removed or you have verified that the area is nonhazardous. Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this product. Substitution of components may impair suitability for Class I, Zone 2, Division 2. Statement 1062
Warning If you connect or disconnect the console cable with power applied to the unit or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
To verify unit operation, perform POST on the device in a nonhazardous location before installation. Statement 1080
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Removing the Access Point from Service
When removing an access point from service, make sure you remove power from the access point before opening the cover and disconnecting the AC input wiring. When removing the AC wiring, the ground connection should be the last to be disconnected.
Conducting Periodic Inspections
The access point should be inspected periodically to ensure normal and airtight operation in the hazardous location environment. Table 3-3 lists the inspection routines and their periodicity.
Conducting Periodic Cleaning
The access point is designed to not require periodic cleaning.
What to Do Next
When you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to the controller, the access point uses the Cisco Adaptive Wireless Path Protocol (AWPP) to bind to another mesh access point (MAP) with the best path to a root access point (RAP) connected to the wired network to a controller. The access point sends a discovery request when powered up. If you have configured the access point in the controller correctly, the controller sends back a discovery response to the access point. When that happens, the access point sends out a join request to the controller, and the controller responds with a join confirmation response. Then the access point establishes a Control And Provisioning of Wireless Access Points (CAPWAP) connection to the controller and gets the shared secret configured on the controller.
Refer to the Cisco Wireless LAN Controller Configuration Guide for more information on configuring, monitoring, and operating your access points.
