Table 4-1 Supported External Antennas for AP1572E
Non-Cisco Antennas
Cisco does not support any third-party antennas. RF connectivity and compliance of third party antennas is the customer’s responsibility. Cisco does not recommend any third-party antennas, and Cisco Technical Assistance Center will not be able to provide any support for third-party antennas. Cisco’s FCC Part 15 compliance is only guaranteed with Cisco antennas or antennas that are of the same design and gain as Cisco antennas.
Antenna Configurations
All versions of the 1570 series access points contain a 4x4:3 2.4 GHz radio and a 4x4:3 5 GHz radio, which are connected to physical antennas/antenna ports numbered 1, 2, 3, and 4. These radios can be configured for both dual-band (both 2.4 GHz and 5 GHz signals coming from the same antenna ports) and single band (2.4 GHz and 5 GHz signals coming from different antennas / antenna ports). The 2.4 and 5 GHz radios connected to these antennas/antenna ports are user configurable as follows:
- The maximum number of active Tx/Rx antennas/antenna ports paths for both the 2.4 and 5 GHz 4x4 radios is restricted to the modes of operation set forth in Section 3.2.7.
- The allowable configurations for the 5 GHz radio are:
- The allowable configurations for the 2.4 GHz radio are:

Installing External Antennas
Note Before connecting power to the access point, ensure that the antennas are attached to the access point
See the section “Supported Antennas” section for details of the antennas supported by the 1572 series access points.
For installation instructions and detailed information on an antenna, refer to that particular antenna’s document located at:
http://www.cisco.com/c/en/us/support/wireless/aironet-antennas-accessories/products-installation-guides-list.html
Follow all safety precautions when installing the antennas. For information on safety, refer to “Safety Precautions when Installing Antennas” section.
Note Omnidirectional antennas are vertically polarized and should be mounted vertically.
Note When operating in the 5GHz UNII-1 band, all Omni Directional antennas should be installed vertically, and all directional antennas should be installed with the main beam aimed parallel to or tilted down toward the horizon.
Antenna N-Type Connector Locations
The AP1572E access point version has two N-type antenna connectors located on the base and two N-type antenna connectors on the head of the access point. The N-type connectors support variety of the Cisco Aironet antennas. For detailed information on these antennas, refer to Antenna Configurations, in chapter 1.

External Antenna Mounting Configurations
Omni Antennas
Omni antennas can be mounted directly to the access point (see Figure 4-2). The supported omni antennas are:
- AIR-ANT2547V-N
- AIR-ANT2547VG-N
- AIR-ANT2568VG-N
- AIR-ANT2440V-N
- AIR-ANT2450V-N
- AIR-ANT2480V-N
- AIR-ANT5140V-N
- AIR-ANT5180V-N
The AP should always be operated with four omni antennas attached for best performance. If you decide to use less than four antennas, ensure that the unused antenna ports are properly covered with an appropriate N-male connector cap (Cisco provides a kit of 10 such caps in AIR-ACC15-N-CAP=).
Figure 4-2 AIR-CAP1572EAC-x-K9 with AIR-ANT2547VG-N
AIR-ANT2513P4M-N=
The AP1572 can be used with a directional antenna that connects via cables (either directly attached to the antenna or with separate cables). See Figure 4-3.
AIR-ANT2513P4M-N= comes with its own mounting kit that will allow it to be mounted to the same pole or wall where the AP1572 is also mounted. Four N-male to N-male cables (such as AIR-CAB005LL-N=) are required to connect the antenna to the AP.
Figure 4-3 AIR-CAP1572EAC-x-K9 with AIR-ANT2513P4M-N=
AIR-ANT2588P3M-N=
The AIR-ANT2588P3M-N= comes with its own mounting kit which allows it to be mounted to the same pole or wall where the AP1572 is mounted. Three N-male to N-male cables (such as AIR-CAB005LL-N=) are required to connect the antenna to the AP. Connect the cables to Ports 1,2, and 3 and install an N-male cap on Port 4. See Figure 4-4.
Figure 4-4 AIR-CAP1572EAC-x-K9 with AIR-ANT2588P3M-N=
AIR-ANT2413P2M-N= and AIR-ANT5114P2M-N=
The AIR-ANT2413P2M-N= and AIR-ANT5114P2M-N= antennas come with their own mounting kits which will allow them to be mounted on the same pole or wall where the AP1572 is mounted. These antennas come with two attached cables to connect directly to the AP. The AP should be placed in single band antenna mode and AIR-ANT2413P2M-N= should be connected to Antenna Ports 1 and 2, and AIR-ANT5114P2M-N= should be connected to Antenna Ports 3 and 4 on the AP. See Figure 4-5
Using an optional antenna mounting bracket kit, the directional antennas AIR-ANT2413P2M-N and AIR-ANT5114P2M-N can also be mounted directly on the AP1572EC access point in a strand mount or pole mount environment. The antenna bracket kit contains four bracket sections and fasteners that you can assemble in multiple configurations to position and aim the directional antenna in a range of positions. For more information on mounting the antenna with the optional mounting bracket, refer to Installing Directional-Antenna Mounting Kits on Cisco 1550 Series Outdoor Mesh Access Points, at the following URL:

Weatherproofing the Type N Connector Joint
Note The following is a general procedure for weatherproofing a Type N connector joint.
Step 1 Ensure that the type N connectors are clean and dry.
Step 2 Apply the oxide inhibitor paste with a Q-tip to each connector pin and the receptacle interiors of both the connectors. This ensures an airtight and watertight seal between the connectors.
Step 3 Fasten the antenna cable’s N-type male connector to the access point’s N-type male connector and tighten as directed in the antenna guide.
Step 4 Wipe away any excess oxide inhibitor paste.
Step 5 Tightly wrap the fastened connectors with two layers of electrical tape, such that the wrapping extends 1 inch past each end of the connection.
Step 6 Tightly wrap the electrical tape layers with two layers of butyl mastic tape, such that the wrapping extends 1 inch past each end of the electrical tape wrapping.
Your RF connection can now stay clean and dry for a long time.

Installing a Lightning Arrestor
Overvoltage transients can be created through lightning static discharges, switch processes, direct contact with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning Arrestor limits the amplitude and duration of disturbing interference voltages and improves the over voltage resistance of in-line equipment, systems, and components. A lightning arrestor installed according to these mounting instructions balances the voltage potential, thus preventing inductive interference to parallel signal lines within the protected system.
Installation Considerations
Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed through on the wall of the protected space.
The importance of obtaining a good ground and bonding connection cannot be overstressed. Consider these points when grounding the lightning arrestor:
Installation Notes
This lightning arrestor is designed to be installed between the antenna cable that is attached to an outdoor antenna and the Cisco Aironet wireless device. You can install the lightning arrestor either indoors or outdoors. It can be connected directly to a wireless device having an external N connector. It can also be mounted inline or as a feed-through. Feed-through installations require 5/8 in. (16 mm) hole to accommodate the lightning arrestor.
Note This lightning arrestor is part of a lightning arrestor kit. The kit contains a lightning arrestor and a grounding lug.
Note When you install the lightning arrestor, follow the regulations or best practices applicable to lightning protection installation in your local area.
Installing the Lightning Arrestor Outdoors
If you install the lightning arrestor outdoors, use the supplied ground lug and a heavy wire (#6 solid copper) to connect it to a good earth ground, such as a ground rod. The connection should be as short as possible.
Figure 4-6 Lightning Arrestor Details

Cable for the Lightning Arrestor
Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible because cable length also determines the amount of signal loss (the longer the run, the greater the loss).
Cisco recommends a high-quality, low-loss cable for use with the lightning arrestor.
Grounding the Access Point
The access point must be grounded before connecting power.
Warning This equipment must be externally grounded using a customer-supplied ground wire before power is applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 366
In all outdoor installations, you must follow these instructions to properly ground the case:
Step 1 If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug.
Step 2 Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied grounding lug.
Note The grounding lug and hardware used must comply with local and national electrical codes.
Step 3 Open the anti-corrosion sealant (supplied), and apply a liberal amount over the metal surface where the ground strap screw holes are located (see Figure 4-7 below).
Figure 4-7 Ground Strap Screw Holes Located on the Right Side of the AP

Step 4 Connect the grounding lug to the access point grounding screw holes using the supplied two Phillips head screws (M4 x10 mm) with lock washers. Tighten the grounding screw to 22 to 24 lb-in (2.49 to 2.71 Nm).
Step 5 Connect the other end of the ground wire to a reliable earth ground, such as a grounding rod or an appropriate grounding point on a metal streetlight pole that is grounded.
Connecting a Fiber-optic Cable to the AP
The Cisco supplied fiber-optic kit enables the access point to support fiber-optic network connections.
Your require the following materials for connecting the fiber-optic cable to the AP:
- Small form-factor pluggable (SFP) transceiver module
- SFP module adapter
- SC or Duplex LC fiber-optic cables. The outer diameter of the fiber optic cable should be 0.24-0.47 inches (6-12 mm).
- Cable gland. The cable gland cannot hold a cable with diameter more than 0.47” (12 mm).
- Adjustable wrench
You can connect the fiber-optic networking cable to the SFP port (labeled '4' on the base of the AP). The small form-factor pluggable (SFP) transceiver module is used to connect the cable to the SFP port. The SFP port provides both Power-over-Cable and backhaul over fiber options. To install the SFP transceiver module and the cable, follow this procedure:
Step 1 Ensure that all power sources have been disconnected from the access point.
Step 2 Remove the covering plug from the SFP port by following the guidelines given in this step.
The SFP port covering plug is designed to be removed only once, and then be replaced with the SFP adapter. The plug does not have a rubber O-ring, but is fixed in place using a sealant on the threads at manufacturing. While removing the plug, you need to ensure that its hex bolt-head does not get stripped. For this:
a. Place the AP on it's back (resting on the heat fins) on a solid, but padded surface, to avoid scratching the paint.
b. Pressing down with your hand on the face of the AP and holding the AP firmly in place, proceed to the next step.
c. Use a 5/8” (16 mm) 6-point socket wrench to loosen the hex bolt-head SFP port plug. Firmly and carefully, turn the socket wrench counter-clockwise to loosen the plug. This requires a torque of 25 ft-lb (34 Nm).
Though not ideal, a 5/8” (16 mm) 12-point socket wrench can be used too. A crescent wrench is to be used only if the socket wrenches are not available. Do not use a pipe or monkey wrench for this task, as it will strip the hex bolt-head.
Step 3 Insert the SFP module into the SFP port, and ensure that it latches properly.
Step 4 Loosen the cable gland’s nut (round end of the cable gland) by turning counterclockwise, but do not remove.
Step 5 Thread the fiber optic cable, from its unterminated end, into the cable gland. See Figure 4-8 and Figure 4-9.
Thread the cable through the gland all the way till the gland is near the SC or LC optic fiber connectors. The cable gland’s nut must remain loose at this time.
Note The SC or LC optic fiber connectors are too big to pass through the cable gland. That is the reason why you need to thread the cable through the gland from the unterminated end (even if the cable is quite long).
Step 6 Insert the SC or LC optic fiber connector-end of the cable, into the SFP module adapter. Do not attach the cable gland to the adapter yet. See Figure 4-10.
Step 7 Insert the SC or LC optic fiber connector into the SFP module and ensure that it latches into place. See Figure 4-10.
Step 8 Add sealant or tape around the adapter's pipe thread, and then it screw into the AP chassis.
Step 9 Keeping the cable gland nut loose, carefully screw the threaded end of the cable gland into the SFP module adapter and hand-tighten. Use an adjustable wrench to tighten the threaded end of the cable gland to 6-7 lb.ft (8.1 to 9.5 Nm).
Step 10 Tighten the cable gland nut until it is properly fastened around the fiber optic cable. Use an adjustable or open-end wrench to tighten to 2.7 to 3.2 lb.ft (3.66 to 4.34 Nm).
When removing this SFP assembly it is absolutely imperative that you proceed in the reverse order of this installation. Start by loosening the cable gland's nut.

Powering the Access Point
The external antenna versions (AP1572E versions) support power over Ethernet input (on the AC version only), power over Ethernet output supporting up to 802.3at devices, internal AC or power over cable power supply options.
If multiple power sources are available, the access point will select the power source which is higher on the following prioritization list. If a power source is removed, access point will automatically switch to the next available power source, as per this list:
1. Power-over-cable or AC (whichever is available on your AP)
3. PoE (available in AC powered versions of AP)
Power-over-Cable
All versions of AP1572I and some versions of AP1572E are equipped with a power-over-cable (PoC) power supply. The power supply can accept quasi-AC signals in the 40 to 90 V RMS range.
Versions of the AP that have a PoC power supply, also have a shunt/fuse interface providing direct in-line access to the PoC AC signal. The AP comes with a shunt in the shunt/fuse location. By removing the shunt or fuse, field technicians can immediately remove power to the AP for service and repairs, and then restore power by re-installing the shunt or fuse. You can install a fuse in the shunt/fuse location to limit the maximum sustained current supplied to the AP to prevent damage to the AP or to the cable plant. Fuses of various amperage are available, and so you can select the appropriate fuse rating depending on the configuration and operating voltage.
For connecting a PoC power supply to the access point, see Connecting PoC Power to the Access Point.
AC Power Supply
Non PoC versions of the AP come equipped with an AC power supply. The power supply is designed to accept AC voltage from 100 V to 277 V RMS.
The following AC power cords are supported:
|
|
|
|---|---|
For connecting Streetlight AC power to the access point, see Connecting Streetlight AC Power.
For connecting an AC power supply to the access point, see Connecting an AC Power Cable to the Access Point.
DC Interface
All versions of the AP have an externally accessible DC input connector. The DC input accepts voltages in the 10 to 16V range. To check the power distribution budget, see https://www.cisco.com/c/en/us/td/docs/wireless/access_point/1570/installation/guide/1570hig/1570_axa.html.
For connecting a DC power supply to the access point, see Connecting a DC Power Cable to the Access Point.
PoE-Input
AC powered versions of AP1572EAC can be powered by UPOE compliant power sourcing equipment.
In addition to being powered by UPOE sources, the access point can also be powered by the AIR-PWRINJ1500-2 power injector.
The access point also supports an Ethernet uplink port (PoE-In). The access point Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access point to the 10BASE-T, 100BASE-T or 1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to optionally supply inline power from the power injector or a suitably powered switch port.
Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.
The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.
Depending on the version of the AP, a 1572 series access point supports these power sources:
The 1572EAC access point can be powered via the PoE input from an in-line power injector or a suitably powered switch port. The AIR-PWRINJ1500-2= power injector can be used.
Do not place the power injector in an unprotected outdoor environment because water could get into the power injector and cause a short circuit and possible fire.
Warning Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards Statement 1033
For connecting the AIR-PWRINJ1500-2 power injector, see Connecting a Power Injector.
For connecting an Ethernet cable to the access point, see Connecting an Ethernet Cable to the Access Point
Restrictions on Features under Different Operating Conditions
To limit the maximum power consumption and ensure thermal integrity of the access point, there are factory-defined restrictions on the features that are active under a given operating condition. This is different for different versions of the AP.
The following restrictions are applicable to all versions under all operating conditions:
– If an SFP device is detected on startup, the cable modem will be disabled and remain disabled until the AP is rebooted.
– If no SFP device is detected on startup, the SFP port will be disabled and remain disabled until the AP is rebooted.
– If no SFP device is detected at startup and the cable modem is connected, then the cable modem will be used as the uplink. The SFP will not be disabled. However, if an SFP device is plugged in later, the AP will require a reboot to choose the SFP port as the uplink.
- You cannot disable any Ethernet ports.
- The power available on the PoE output port can be 802.3at, 802.3af, or disabled depending on other configuration options.
- PoE-Output is disabled when PoE-Input voltage is present.
- If the AP is powered by other means and then switches to UPOE, the AP will automatically reconfigure itself as required.
- The access point has protection mechanisms to prevent overheating by reducing certain functionalities, if internal temperatures exceed factory-defined limits. Protection measures include reducing the number of active transmit paths on one or more radios. The number of active transmit paths will return to the user’s selected configuration when the overheating condition subsides. However, if the protection measures do not sufficiently reduce the temperature, then the AP will ultimately power down, with the LEDs flashing yellow at flashes per second. When the overheating condition subsides, the AP will power up automatically.
The following tables show the maximum radio transmission paths for various versions of the AP depending on the kind of input power, cable modem status, and SFP port status.
Note The AP supports all modes described in the following tables, in ambient temperatures of -40°C to +45°C in all supported orientations, with a solar loading of 753 Watts/m2. For details on the operating temperature ranges of the access point, see Access Point Operating Temperature Specifications.

Connecting a Power Injector
The 1570 Series Access Points supports the AIR-PWRINJ1500-2= (100-240 VAC input, indoor use only) power injectors.The power injector provides (AIR-PWRINJ1500-2=) 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.
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” section).
Step 2 Review Figure 3-1 to identify the components needed for the installation.
Note The 1500 power injector can only be used in an indoor environment, therefore, the cable from the injector must travel from the protected location to the outside mounted access point.
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
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 5 Connect a shielded outdoor-rated Ethernet (CAT5e or better) cable between the power injector and the PoE-in connector of the access point.
Step 6 Connect the Ethernet cable to the access point PoE-In port (see “Connecting an Ethernet Cable to the Access Point” section).

Procedure for Connecting AC power Cable to Access Point
To connect an AC power cable to the access point, perform these steps:
Step 1 Prior to applying AC power, ensure the access point is grounded (see Grounding the Access Point).
Step 2 Turn off power to the AC power source at the designated circuits.
Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
When connecting the access point AC power connector, always connect the access point end of the cable FIRST. When removing the AC power connector, always disconnect the access point end of the cable LAST.
Step 3 Align the numbered holes in the AC power cable connector with the pins in the access point AC power port (on the base of the 1572EAC. See Figure 1-10), and push the cable connector into the access point connector.
Step 4 When the connector is fully seated in the AC port, hand tighten the cable connector ring by turning it clockwise.
Connecting PoC Power to the Access Point
The Power-over-Cable (PoC) configuration contains a cable modem, RF splitter (within the AP), and a cable stinger connector. The cable stinger port for Power-over-Cable connections is labeled '1' on the base of the AP (see Base of the AP).
Note To ensure system performance, with respect to immunity from external electromagnetic fields, use a well shielded coaxial cable, preferably a quad-shield cable.
Note The AP1572IC and AP1572EC versions of the AP are classified as a type “Hazardous Voltage Secondary” circuit as per the UL/IEC/EN 60950-1 safety standard. The cable distribution network used with this versions must provide transient reduction to the level for this type of circuit classification (that is, 500V transient/lightning surge).
To connect cable PoC power to the access point, follow these steps:
Step 1 Ensure that all power sources have been disconnected from the access point and that the AP is properly grounded. See Grounding the Access Point.
Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
Step 2 Remove the attenuator plug (port labeled '7'), and the Shunt plug (port labeled '8') from their ports on the back of the AP. Follow your cable company's procedures to measure the cable signal strength and possibly adjust signal attenuation externally to the access point or on the RF splitter.
For more information on the attenuator and shunt ports, see Installing Attenuators, Fuses, and Shunts
Step 3 The Cisco-supplied cable stinger connector pin is 29-100357-01. If you are using a third-party cable stinger connector pin, then cut it down to the correct length using the trim measure provided right next to the Power-over-Cable port (labeled '1' on the base of the AP).
The cable stinger connector pin must be 1.70 ± 0.05 inch (43.1 ± 1.2 cm) in length, but your are encouraged to use the trim measure on the AP as the scale of measure.
Step 4 Insert the cable stinger connector pin into the Power-over-Cable port. The Power-over-Cable port is equipped with a spring-loaded stinger seizing mechanism. Hence, push the stinger all the way in until the threads hit.
Step 5 Thread the cable stinger connector ring into the PoC connector opening. Use an adjustable wrench to tighten the connector to 6 to 7 ft lbs (8.1 to 9.5 Nm).
Step 6 Connect the cable company's PoC cable to cable stinger plug as per their specifications.
Step 7 Turn on cable PoC power.
Step 8 Reinstall the RF splitter shunt plug, and the attenuator plug.
Installing the GPS Antenna
All models of the 1570 Series support location information when the optional GPS antenna (AIR-ANT-GPS-1) is installed and connected. The AP has two mounting positions for the GPS antenna, on the head of the AP and on the back of the AP, which need to be used depending on whether the AP is horizontally or vertically oriented when deployed (see Figure 4-19 and Figure 4-20).
Note Ensure that the GPS antenna always has a clear unobstructed view of the sky, for proper functioning.
Step 1 Remove the protective cap covering the access point’s GPS antenna connector port.
Step 2 Screw down the GPS antenna connector onto the AP's GPS antenna connector port, just enough so that it doesn't fall off.
Step 3 If the AP is mounted horizontally, screw down the GPS antenna at the designated spot on the back of the AP (see Figure 4-19).
If the AP is mounted vertically, screw down the GPS antenna at the designated spot on the head of the AP (see Figure 4-20).
Step 4 The GPS antenna is fixed to the AP using two M3.5x0.6x8 mm Pan Head Phillips stainless steel screws.
Step 5 Fully tighten the GPS antenna connector onto the access point's GPS antenna connector port.

Installing Attenuators, Fuses, and Shunts
Installing an Attenuator Plug
You can install an attenuator plug on the RF splitter, in port 8 on the back of the access point (see Figure 1-4).
Plug-in attenuator pads produce flat (even) loss across the forward and reverse frequency spectrum. Pads are used during station balancing to adjust signal levels as needed. The loss (in dB) produced is equal to the pad value printed on the top of the pad.
Using a Signal Test Probe
You can use test probes (such as the Communication Associates CA008927) to measure the DS signal level directly from the attenuator plug-in interface in port 8 on the back of the access point (see Figure 1-4).
You need to remove any installed attenuator pads, which will disconnect the cable modem from the HFC network. You can then insert the test probe into the plug-in interface, providing an F-connector interface to directly measure downstream signal levels. Based on the measured signal level, you can decide on an attenuator value and then plug in the corresponding attenuator pad into the port.
Installing a Fuse or Shunt
You can install a power fuse or a power shunt in port 7 on the back of the access point (see Figure 1-4). Fuses with different fuse ratings are available from Cisco.
Note By default a 20 A fuse is provided as shunt.
Handling the AP when installing Attenuators, Fuses, and Shunts
To access port 7 or port 8 (see Figure 1-4):
- For strand mounted APs, you can access ports 7 and 8, without having to dislodge the AP from its mount.
- For pole and wall mounted APs, you can following one of the following procedures, depending on your mounting kit,
For pole mounted and wall mounted APs, mounted using PMK1 or PMK2, to access port 7 or port 8:
Step 1 Slide the AP up, off the wall mount bracket’s key hole slots.
Step 2 Remove the four M8 x 12mm hex head bolts from the back of the AP, and then fix them on the face of the AP in the screw holes intended for future external module support (see Face of the AP). Do not fully tighten the bolts.
Step 3 With the face of the AP aligned to the wall mount bracket, slide bolts on the face of the AP, down into the key hole slots on the wall mount bracket.
Step 4 Unscrew the protector cap of the port and proceed with your task. When you are done with your task, retrace your steps to mount the AP back properly. See the following sections to ensure that you have properly mounted the AP.
For pole mounted and wall mounted APs, mounted using PMK3, to access port 7 or port 8:
Step 1 Remove the three M8 x 12mm hex head bolts, used in the key hole type screw holes on the PMK3 wall mount bracket, as marked in Figure.
Step 2 You can now rotate the AP outwards from the mount, using the remaining one bolt as the pivot. Rotate the AP out just enough access port 7 or 8.
Note You many need to loosen this bolt just enough to rotate the AP out.
Step 3 Unscrew the protector cap of the port and proceed with your task. When you are done with your task, retrace your steps to mount the AP back properly. See Pole Mount Kit 3 to ensure that you have properly mounted the AP.
