How to Get Help
Foundry Networks technical support will ensure that the fast and easy access that
you have come to expect from your Foundry Networks products will be maintained.
Access Points contain radio devices that communicate with the Meru Controller and
form the wireless LAN (WLAN). The Meru Controller and Access Points connect to the
site’s wired LAN through wired switches. Wireless clients associate with the Access
Points as they roam throughout the WLAN. As such, they are an extension of the wired
LAN, providing the wireless benefits of client mobility, enhanced access, and
dynamic network configuration.
The AP320i Access Point is an internal-antenna AP with two dual-band 802.11n radios
and 3x3 MIMO and internal antennas.
Features for the AP320i include:
Internal antennas
802.11n support with channel bonding in both 2.4GHz and 5GHz frequency bands.
Channel bonding combines two 20Mhz channels into a single-wide 40Mhz channel
for increased throughput.
Plug and Play deployment using centralized controller platforms
Multi-layered security including standard WPA2 features such as automatic traffic
inspection
Standard 802.3af PoE support and support for many 802.3at devices
Air Traffic Control technology for 802.11n devices and legacy a/b/g devices
Channel span architecture that requires no channel planning or configuration
The AP200 series provides two models that conform to the specifications provided by
the IEEE 802.11a and 802.11g protocols and provide backward compatibility for the
802.11b protocol. An AP200 works with most standard Wi-Fi clients.
The AP201 houses a single 802.11a/b/g radio device.
The AP208 supports a maximum of two radio devices that can simultaneously run
two protocols (802.11b, g or b/g on interface 1 and 802.11a on interface 2).
Alternately the second radio can be configured to run as an RF monitor to a Meru
Controller, providing real-time status of RF activity to optimize the wireless
network.
The AP200 series (referred hereafter as the AP200, unless specifically referring to the
AP201 or AP208) is housed in a metal case with a plastic removable cover. As such, it
can be used for plenum installations when the plastic cover is removed.
The AP150 has two 802.11 radios for simultaneous 802.11a and 802.11b/g WLAN
access. It is an ideal option for enterprise-wide data-only WLAN implementations and
small-sized converged data and voice WLAN implementations. The AP150 works in
conjunction with Meru Controller products and can be easily integrated into existing
Layer 2 and Layer 3 wired network environments to provide enterprise-grade Wi-Fi
access with multi-layered security options, basic VoWLAN support, centralized
configuration, troubleshooting tools, remote management and RF visualization capabilities.
The AP150 has the following features:
Dual 802.11b/g and 802.11a radios
Simultaneously support for 802.11b, 802.11g, and 802.11a clients
Contention Management for high density of data clients
Basic VoWLAN QoS support for small density of voice clients

Safety Precautions
IMPORTANT—Read and follow the regulatory instructions in Appendix B before installing and operating
this product.
If an optional power supply is used, it must be one supplied by Meru Networks.
The AP300 is intended only for installation in Environment A as defined in IEEE 802.3af. All interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection.
Read this section if you have both AP200 and AP300 active simultaneously on the same network with ABG
legacy clients. The following best practices should be followed to get optimal performance from such a mixed
network.
Do not deploy AP200 and AP300 at the same physical location; we recommend no overlapping
coverage between AP200 and AP300.
If AP200 and AP300 must have overlapping coverage, make sure the ESS profiles on both AP types
are unique. The chart below shows two scenarios, one supported, one not supported.
AP300i and AP300 are interchangeable and fully compatible to share a virtual cell. It's like having
two AP300s with different antennas. The only difference is that AP300i is detected as a such in the
UI of the controller.
AP200 is using Virtual Port and BSSID Virtual Cell (AP200 could also be using Shared BSSID Virtual
Cell.)
AP300 is using Virtual PortBSSID Virtual Cell.
AP200s and AP300s are on the same channel. (AP200 and AP300 could also be on different channels.)
AP200s and AP300s are on the same controller. (AP200 and AP300 could also be on different
controllers as long as each controller has a unique controller index.)
Power requirements vary, depending on which AP300 radios are deployed and what MIMO mode is used.
See the chart below for supported power sources for different radio configurations.

802.af PoE Usage
When using System Director 3.6/4.0 and 802.3af PoE, Meru supports radios set to any MIMO settings
except 3x3 on dual radios. This is because two radios set to 3x3 MIMO using an 802.3af switch may not
have enough power if the cable is too long. Shorter cables frequently work, however. Meru supports:
Single 3x3 radio
Dual 2 x 2 radios
Dual radio with one set to 2x2 and the other one set to 3x3
When using System Director 4.0 and 802.3af, the AP300 MIMO configuration is limited to the following:
3x3 for the 5 GHz radio
2x2 for the 2.4 GHz radio
802.3at PoE Usage
When using System Director 3.6/4.0 and 802.3at, the following radio combinations are recommended:
Single 3x3 radio
Dual 2 x 2 radios
Dual radio with one set to 2x2 and the other one set to 3x3
Dual 3x3 radios are recommended with a limitation. Use 802.3at power for two 3x3 MIMO radios
when the switch has a high enough power output to support all devices on the PoE. Calculate the
amount of power needed by each AP300/AP300i in 3x3 mode (13 watts), add that to power required
by other PoE devices on the switch and compare that value to the total power output from the
switch.
The calculation for 802.3at PoE use looks something like this:
(Number of AP300s * 13watts) + (sum of all other PoE devices power requirements) <= switch
power provided
Installation Requirements
An array of holes on the mounting bracket allows the AP300 to be mounted on the wall and over junction boxes or molly bolts. There are holes for passing the PoE Ethernet or external power supply cable
through the bracket if the bracket is mounted on a junction box. A template of this bracket is included
in Appendix E of this guide.
The AP300 has a security cable slot so you can lock the AP300 with a standard security cable, such as
those used to secure laptop computers.
Purchase optional mounting kits to mount the AP300 either from the ceiling or inside an enclosure:
Above hanging ceiling tiles. Suitable for use in environmental air space in accordance with the
Section 300-22(c) of the National Electric Code and Sections 2- 128.12 - 010 (3) and 12 - 100 of the
Canadian Electrical Code. Part 1. C22. 1.

Install the Access Point
Select a Location
All AP300 interconnected equipment, including the associated LAN connection, must be contained
within the same building. In addition, the AP300 location should meet the following conditions:
Relatively unobstructed access to the stations the AP serves. Select a location with minimal physical
obstructions between the AP and the wireless stations. In an office with cubicles, mounting the APs
below a hanging ceiling (plenum is supported) or the wall near the ceiling provides the least
obstructed communications path. On a wall, orient the AP300 horizontally so that you can read the
Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO
performance.
Access to wall outlet or a to aPower over Ethernet (PoE) connection to the network switch servicing
the controller.
AP300 is designed to provide 360 degree omni-directional coverage as illustrated below.
Figure 8: Coverage Pattern for AP300 When Ceiling Mounted
Most installations receive the best coverage using the following guidelines:
Install APs toward the center of the building.
Place APs about 80 feet apart.
Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.
For best coverage, orient antennas as shown in Figure 6.
Attach the Provided Antennas
All AP300s have six external antenna ports, labeled 1 - 6. These units operate with six antennas
attached, even though some configurations don’t use all six. Instead of attaching an antenna, you can
cap unused antenna connectors with 50 ohm Reverse Polarity SMA terminators. (For a list of approved
terminators, see http://www.merunetworks.com/merusupport
only for indoor use unless they are mounted in an outdoor enclosure (see Mount AP300 in a Hoffman
Enclosure). To achieve the best performance from your AP300, position antennas at a 90 degree angle
relative to each other as shown in Figure 6. The antennas do not have to be oriented exactly as shown
in the figure, but it is important to maintain the relative angles. If for some reason you are unable to
maintain those angles, the network still operates, but you may experience up to 20% drop in throughput
depending on the antenna orientation.
The following antenna connections are used during operation of the AP310/AP310-M.
Radio 1 Antenna Connectors for AP310/AP310-MRadio2 Antenna Connectors for AP310/AP310-M
Ant1, Ant2, Ant3NA
Do not leave any antenna connectors unterminated. All connectors on the AP must be terminated with
antennas or with 50 ohm Reverse Polarity SMA terminators. (For a list of approved terminators, see
http://www.merunetworks.com/merusupport
.
The attached antennas must be the same model; if you replace one antenna, replace them all.
Install the Remote Antenna Mount (optional)
Use the optional Meru Remote Antenna Mount (ACC-ANT-MIMO-MNT) for one or both AP300 radios to
remotely connect the AP300 antennas. The Remote Antenna Mount allows you to relocate either your
current antennas or the optional high-gain dipole antennas to a location with clearer signal paths to
the other wireless devices in your network. The Remote Antenna Mount can be installed either below
the ceiling tile or on the wall. The default orientation for the mount is suitable for a ceiling mount,
but you can attach the mount to a wall with some modifications.
Use one mount per radio; for example AP310/AP310-M needs one unit, and AP320 needs two units.
The Remote Antenna Mount uses low-loss plenum rated LMR195 cable and SMA connectors.

AP300 ships with a detachable mounting bracket. The AP300 is d esigned to be compatible w i th brackets
supplied by Meru and by other vendors as follows. The AP300 mounts directly on the AP150 mounting
bracket. If you are replacing AP200s/AP300s, the AP300 bracket can be mounted on the old
AP200s/AP300s bracket with included shoulder screws; you don’t need to remove the old brackets.
AP300 can also be directly mounted on third-party brackets such as Proxim AP4000 and Cisco standard
brackets.
You can mount an AP300 in the following ways:
Mount AP300 Horizontally on a Shelf
Mount AP300 Vertically on a Wall
Mount AP300 Below a Suspended Ceiling
Mount AP300 Above a Suspended Ceiling (Plenum)
Mount AP300 in a Hoffman Enclosure
Mount AP300 Horizontally on a Shelf
When mounting an AP300 horizontally, remove the mounting bracket. Be sure to position the antennas
vertically when an AP300 sits on a surface.
Mount AP300 Vertically on a Wall
Note:
same bracket. If you are replacing AP300s, the AP300 bracket can be attached to the old bracket with
included shoulder screws; you don’t have to remove the old brackets. This bracket will also mount
seamlessly into the Proxim AP4000 bracket and standard Cisco brackets.
To mount an AP300 on a wall:
1. Using the bracket holes as a guide, mark the location on the wall for the two AP bracket mounting
2. Drill holes at the locations you marked:
3. If you are using plastic anchors, install them in the holes.
4. Screw in the screws most of the way.
5. Mount the bracket on the screws, placing the circular portion of the keyhole mounts over the screw
If you are replacing AP150s, you can use the existing brackets: the AP150 and AP300 use the
screws. If possible, center the mounting screws on a wall stud. If you do not center the mounting
screws on a wall stud, use plastic wall anchors. Orient the AP300 horizontally so that you can read
the Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO
performance.
— 3/16-inch holes if you are using plastic anchors
— 1/8-inch holes if you are using only the screws
heads and sliding the bracket down.
6. Connect one end of the Ethernet cable to the switch and the other end to the AP300 Ethernet port.
8. Align the AP300 mounting posts over the circular portion of the keyhole mounts, push the AP in and
slide the AP down until it engages with the locking detents (see Figure 9). You should hear it snap
in place.
9. For each antenna, loosen the knurled ring at the base of the antenna, orient the antenna and then
retighten the ring.
10. Connect one end of the PoE 100BaseT Ethernet cable to the 100/1000 Ethernet connector.
Caution!
Be sure to connect the Ethernet cable to the Ethernet port; the cable can
mistakenly be plugged into the Console port. If you do this. the AP won’t power up.
Use the optional T-bar box hanger mounting kit (see Mounting Brackets for the part number) to mount
AP300 above suspended ceiling T-rails (see Figure 10 and Figure 11). The installation attaches the Tbar box hanger to the ceiling rails and then the AP300 attaches to the T-bar box hanger. We recommend
that you mount the AP300 no more than half way up the supports as shown in both Figure 10 and
Figure 11. Also note that AP300 mounted above the ceiling has about 2-3 dBm less RF coverage than
AP300 mounted under the ceiling.

Install the AP300
The AP300 with the metal enclosure exposed meets the requirements for fire resistance and low
smoke-generating characteristics required by Section 300-22(C) of the National Electrical Code (NEC)
for installation in a building’s environmental air space.
You may need to modify thicker tiles to support this installation.
Warning!
When installed in air-handling spaces, such as above a suspended ceiling,
power the AP300 only with a PoE, not a power supply. See Power Supplies for part
numbers.
Warning!
Any Fast Ethernet (FE) cables installed in air-handling spaces should be
suitable under NEC Article 800.50 and marked accordingly for use in plenums and airhandling spaces with regard to smoke propagation, such as CL2-P, CL3-P, MPP (Multi
Purpose Plenum), or CMP (Communications Plenum). Use Ethernet cable that meets
the requirements for operating in plenums and environmental air space in
accordance with Section 300-22(C) of the NEC.
To mount an AP300 above the ceiling with the optional T-bar kit, follow these steps:
1. Determine the location on the ceiling rails where the AP will be mounted and remove the ceiling
tile.
2. Unpack the T-bar hanger kit and unfold the legs of the T-bar hanger.
3. Locate the bracket mounting clip holes on the mounting bracket (see Figure 10). One hole attaches
the bracket perpendicular to the box hanger; the other mounts the bracket parallel to the box
hanger.
4. Attach the U-joint of the clip to the T-bar and snap in place (seeFigure 12).
Figure 12: Attaching the Mounting Bracket to the Box Hanger for Face Up Orientation
.
Figure 13: Attaching the Mounting Bracket to the Box Hanger for Face Down Orientation
.
5. Pass the long end clip through the large center hole to the underside of the mounting bracket clip
and then attach the bracket to the clip using the supplied screw (see Figure 12 for orientation).
6. Hold the AP300 next to the mounting bracket to estimate the height of the T-bar box hanger. You
need to provide enough clearance for the external antennas that point down, while mounting the
T-bar on the lower half of the support rails for stability.
7. Adjust the height of the box hanger using the height adjusting screws (see Figure 9).
8. Clip the box hanger T-rail clips to the ceiling rails, making sure they are securely attached.
9. Connect a drop wire to a building structural element and through the hole provided in the bracket
mounting clip. The U.S. National Electrical Safety Code requires this additional support.
10. Connect the posts of the AP300 to the three keyholes of the mounting bracket and slide into the
keyhole, ensuring the locking detent is engaged. You will hear a click.
11. For each antenna, loosen the knurled ring at the base of the antenna, point the antenna down, then
retighten the ring.
12. Connect one end of the PoE Ethernet cable to the Ethernet connector.
Caution!
mistakenly be plugged into the Console port. If you do this. the AP won’t power up.
Note:
13. Check that the AP300 is operating correctly before replacing the ceiling tile to the ceiling. Verify
correct operating using the LEDs, as shown in Check AP300 LED Activity.
Be sure to connect the Ethernet cable to the Ethernet port; the cable can
Use a shielded Cat 5e (or greater)Ethernet cable in order to comply with
international electromagnetic emissions limits.
Mount AP300 in a Hoffman Enclosure
Meru has designed a custom mounting bracket compatible with a Hoffman enclosure (www.hoffmanonline.com). This bracket is available exclusively through Meru and orderable as part number ACC-AP300-
BHE. To mount an AP300 in a Hoffman enclosure, follow these steps:
1. Place AP300 upside down on a soft flat surface.
2. Remove and discard the wall/ceiling mounting bracket.
3. Attach either the provided antennas or an external antenna.
4. Remove and discard the four rubber feet.
5. Position the Hoffman bracket (ACC-AP300-BHE) onto the back of the AP300 with the four Hoffman
6. Using a Phillips screw driver, attach the bracket using the two supplied 6-32 3/16 SEMS screws.
7. Flip the assembly over and mount into the Hoffman enclosure, attach the Ethernet cable to the
AP300 rotating the assembly to place the Ethernet cable within the enclosure.
8. Using a Phillips screw driver, tighten the four bracket screws to the enclosure.
9. Adjust the antennas as needed.
Check AP300 LED Activity
When AP300 first connects to the controller (and any time the access point is rebooted), the AP initializes and is then programmed by the controller. When the AP first powers up, all LEDs are green.
Figure 15: AP300 Status LEDs
After the AP300 is connected, check the status of the LEDs. The functions of the five LEDs are described
below.
off—no power
green—booting stage 1
blinking green and off—booting stage 2
blinking green and white—discovering the
controller
blinking green and blue—downloading a
configuration from the controller
blinking blue and off—AP is online and
enabled, working state
blinking red and yellow—failure; consult
controller for alarm state
off—no power or no link
green—link status OK (at any speed)
green/blinking—activity (at any speed)
red—auto negotiation failure
If the status LED is blinking red and
yellow, there is an alarm on the AP.
Determine what the alarm is by
clicking Monitor > Dashboard > Alarms and looking at the AP alarms.
You can also use the CLI commands
show alarm and show log.
If the LAN LED is red, auto
negotiation failed. This means that
you have a problem with cabling or
with the AP’s switch.
If one of the radio LEDs is yellow, it is
either disabled or in scanning mode.
To see if the AP is disabled, click
Configuration > Wireless > Radio >
select a radio and then look at
Administrative Status, which should
green—radio enabled
green blinking—data activity
yellow—disabled or in scanning mode
red—failure
be set to Up. To see if the AP is in
Scanning Mode, click Configuration > Wireless > Radio > select a radio and
look at AP Modes, which should be set
to Normal Mode.
If one of the radio LEDs is red, the
radio failed. Check the alarms
(Monitor > Dashboard > Alarms),
diagnostics (Monitor > Diagnostics >
Radio), and statistics (Monitor >
Dashboard > Radio) on the AP’s
controller to determine the cause.
Where to Go From Here
Where to Go From Here
Now that the AP300 is installed, refer to the Meru System Director Getting Started Guide for instructions on initializing the hardware. Return to this chapter to check the status of the LEDs once the WLAN
is operational.
AP320i is supported by System Director versions 3.6.1 and greater, but full support begins with System
Director release 4.0. Because of this, when using AP320i with System Director 3.6.1, the unit shows as
an AP300, for example AP320 instead of AP320i. All AP320i units still function correctly, they just
display as AP300 because AP320i did not exist when System Director 3.6.1 was released.
This chapter describes how to install and configure an AP320i. It contains the following sections:

Safety Precautions
IMPORTANT—Read and follow the regulatory instructions in Appendix B before installing and operating
this product.
If an optional power supply is used, it must be one supplied by Meru Networks.
The AP320i is only intended for installation in Environment A as defined in IEEE 802.3af. All interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection.
Read this section if you have both AP200 and AP320i active simultaneously on the same network. The
following best practices should be followed to get optimal performance from such a mixed network.
Do not deploy AP200 and AP300/AP320i at the same physical location; we recommend that there be
no overlapping coverage between AP200 and AP300.
If AP200 and AP300/AP320i do have overlapping coverage, make sure the ESS profiles on both AP
types are unique. The chart below shows two scenarios, one supported, one not supported.
AP320i and AP300 are interchangeable and fully compatible to share a virtual cell. It's like having
two AP300s with different antennas. The only difference is that AP320i is detected as a such in the
UI of the controller.
Confirm that the shipping box contains the following:
AP320i with an attached ceiling mounting bracket
Wall mount bracket with screws
Small locking key for ceiling or wall mount locking
Determine Power Requirements
Power requirements vary, depending on which AP300 radios are deployed and what MIMO mode is used.

802.af PoE Usage
When using System Director 3.6/4.0 and 802.3af PoE, Meru supports radios set to any MIMO settings
except 3x3 on dual radios. This is because two radios set to 3x3 MIMO using an 802.3af switch may not
have enough power if the cable is too long. Shorter cables frequently work, however. Meru supports:
Single 3x3 radio
Dual 2 x 2 radios
Dual radio with one set to 2x2 and the other one set to 3x3
When using System Director 4.0 and 802.3af, the AP300 MIMO configuration is limited to the following:
3x3 for the 5 GHz radio
2x2 for the 2.4 GHz radio
When using System Director 3.6/4.0 and 802.3at, the following radio combinations are recommended:
Single 3x3 radio
Dual 2 x 2 radios
Dual radio with one set to 2x2 and the other one set to 3x3
Dual 3x3 radios are recommended with a limitation. Use 802.3at power for two 3x3 MIMO radios
when the switch has a high enough power output to support all devices on the PoE. Calculate the
amount of power needed by each AP300/AP320i in 3x3 mode (13 watts), add that to power required
by other PoE devices on the switch and compare that value to the total power output from the
switch. The calculation for 802.3at PoE use looks something like this:
(Number of AP300s * 13watts) + (sum of all other PoE devices power requirements) <= switch
power provided

Additional Equipment
A power source is needed to power the AP300. See Determine Power Requirements. If you want to lock
an AP320i to the ceiling or wall, you need a small key like the ones used to lock suitcases.
All AP320i interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection. Ceiling mounting is recommended but wall
mounting is also supported. In addition, the AP320i should be mounted in a location that meets the
following conditions:
Relatively unobstructed access to the stations the AP serves. Select a location with minimal physical
obstructions between the AP and the wireless stations. In an office with cubicles, mounting the APs
below a hanging ceiling (plenum is supported) or the wall near the ceiling provides the least
obstructed communications path. On a wall, orient the AP300 horizontally so that you can read the
Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO
performance.
Access to wall outlet or a to aPower over Ethernet (PoE) connection to the network switch servicing
the controller.
AP320i is designed to provide 180 degree omni-directional coverage as illustrated below. Plan placement with this pattern in mind.
Figure 16: Coverage Pattern for AP320i When Ceiling Mounted
ceiling
floor
Most installations receive the best coverage using the following guidelines:
Install APs toward the center of the building.
Place APs about 80 feet apart.
Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.
If you install AP320i on a pole, keep in mind that coverage will be 180 degrees. Do not mount two
AP320is back to back on a pole to achieve 360 degree coverage, however, because the two units
could interfere with each other.
Install the Access Point
The AP320i ships with a detachable ceiling mounting bracket, making the unit ready for ceiling
mounting. You can also remove the ceiling-mount bracket and use the included wall-mount bracket.
The wall mount bracket can be attached to sheetrock, wall studs, or another wall bracket supplied by
Meru and by other vendors. If you are replacing AP200s/AP300 wall brackets, the AP320i bracket can
be mounted on top of the old AP200/AP300 bracket using shoulder screws (not included); you don’t
need to remove the old brackets. AP320i can also be directly mounted on standard third-party wall
brackets such as the Proxim AP4000 bracket and standard Cisco brackets. You cannot, however, mount
AP320i directly on an AP150 wall-mount bracket; in this case, you must remove and replace the AP150
bracket. Installation directions are provided below.
Mount AP320i in any of the following ways:
Mount AP320i On a Suspended Ceiling
Mount AP320i Above a Suspended Ceiling (Plenum)
Mount AP320i Vertically on a Wall
Set AP320i on a Shelf
Mount AP320i Below a Recessed Ceiling
The AP320i ships with a ceiling mount bracket already connected to the unit and an additional separate
wall bracket. When wall mounting a unit, you will attach the wall mount bracket to the wall, then
attach the ceiling bracket (including AP320i) to the wall bracket. If you are replacing an AP200 or
AP150, the AP320i wall bracket can be mounted on top of the old bracket using shoulder screws (not
included - see Installation Requirements); you don’t need to remove the old brackets.If you are
replacing an AP300 or third-party brackets such as the Proxim AP4000 bracket and standard Cisco
brackets, the AP320i wall bracket can also be mounted on top of the old bracket (no additional screws
required).
To mount an AP320i on sheetrock or wall studs, follow these steps:
1. Using the wall bracket holes as a guide, mark the location on the wall for two AP bracket mounting
screws. Orient the connected AP300 horizontally so that you can read the Meru logo without tilting
your head at 90 degrees - this orientation provides optimum MIMO performance.
Figure 20: AP320i Wall Bracket
If possible, center the mounting screws on a wall stud. If you do not center the mounting screws on a
wall stud, use plastic wall anchors.
2. Drill holes at the locations you marked:
— 3/16-inch holes if you are using plastic anchors
— 1/8-inch holes if you are using only the screws
3. If you are using plastic anchors, install them in the holes.

Mounting Above a Suspended Ceiling
The optional T-bar box hanger mounting kit allows the AP200 to be mounted above
suspended ceiling T-rails (see Figure 22). The installation attaches the T-bar box
hanger to the ceiling rails using clips. The AP200 attaches to the mounting bracket
that is attached to the T-bar box hanger.
The AP200 antennas should point straight down for this type of installation. You may
need to modify thicker tiles to support this installation.
Warning!
the AP200 is to be powered via PoE only (PoE is required).
When installed in air-handling spaces, such as above a suspended ceiling,
The AP200 with the metal enclosure exposed meets the requirements for
fire resistance and low smoke-generating characteristics required by Section 30022(C) of the National Electrical Code (NEC) for installation in a building’s
environmental air space. You must remove the plastic enclosure to reveal the
plenum-rated AP200 metal case for installations above a suspended ceiling.
Additionally, you must use Ethernet cable that meets the requirements for operating
in plenums and environmental air space (in accordance with Section 300-22(C) of the
NEC).
Warning!
Any Fast Ethernet (FE) cables installed in air-handling spaces should be
suitable under NEC Article 800.50 and marked accordingly for use in plenums and airhandling spaces with regard to smoke propagation, such as CL2-P, CL3-P, MPP (Multi
Purpose Plenum), or CMP (Communications Plenum).

Now that the AP200 is installed, go to the Meru System Director Getting Started
Guide for instructions on initializing the hardware. Return to this chapter to check
the status of the LEDs once the WLAN is operational.
Access point status LEDs are provided on the Ethernet connector and on the face of
the AP200.
Ethernet Connector LEDs
After the AP200 is connected, the LEDs near the RJ-45 connector should light, as
shown in Figure 25.
Figure 25: RJ-45 LEDs
Checking LED Activity
The green LED on the left blinks if any Ethernet activity is taking place. If there is
no Ethernet activity, the LED is off. The LED on the right is solid green if an Ethernet
link is present. If no Ethernet link is present or connectivity is lost, the LED is off.
AP200 Status LEDs
Four status LEDs on the face of the AP200 also light, as shown in Figure 26.
The functions of the status LEDs are described below.
When the AP200 is first connected to the controller and any time the access point is
rebooted thereafter, the AP initializes with and then is programmed by the
controller. When the AP is first powered up, all LEDs are green. Thereafter, the

If you choose not to use the AP150 mounting bracket, the backside of the AP150
contains two keyholes to accommodate a simple wall mount.
A mounting bracket can be used for many wall mounting configurations. The AP150
bracket mounting studs are placed so they can be used with brackets supplied by
other vendors or to replace an AP100. An array of holes on the mounting bracket (see
Figure 27) allow it to be mounted on the wall and over junction boxes or molly bolts.
There are also holes for passing the PoE Ethernet or external power supply cable
through the bracket if the bracket is mounted on a junction box.
Additional optional mounting kits are available for mounting the AP150 above or
below a hanging ceiling, using the mounting bracket.
The AP150 is not certified for plenum installations, and should not be installed
in the plenum space.
Note:
The AP150 has two security cable slots (one on each side of the AP150) so you
can secure the AP150 with a standard security cable, such as those used to secure
laptop computers.
The following recommended mounting locations provide the best reception for the
AP150:
On a horizontal surface, such as a table or a desk
On a vertical surface, usually a wall
Below a hanging ceiling

Selecting a Location
The AP150 requires a location that meets the following criteria:
Relatively unobstructed access to the stations the AP serves
Power over Ethernet (PoE) connection to the network switch servicing the
controller.
APs can obtain their power from 802.3af standard Power over Ethernet (PoE)-compatible network switch or PoE power injector installed between the switch and the
AP150.
AP150 and AP300 work with all switches that support STANDARD 802.3af.
Select a location with minimal physical obstructions between the AP and the wireless
stations. In an office with cubicles, mounting the APs below a hanging ceiling or the
wall near the ceiling provides the least obstructed communications path. For an
external power supply connection, ensure the power source is near to where the
AP150 will be mounted.
Most installations receive the best coverage using the following guidelines:
Install APs toward the center of the building.
Do not install APs near metal objects, such as heating ducts, metal doors, or
electric service panels.
Relative to the ground, orient the antenna up or down, not sideways.
Note:
environment. Place access points accordingly. Note that the AP300 Power Adaptor
can also be used for AP150.
The AP150 is only intended for installation in Environment A as defined in IEEE
802.3af. All interconnected equipment must be contained within the same building,
including the interconnected equipment's associated LAN connection.
The previous guidelines are general guidelines. Each site has its own unique
Attaching the AP150 Antennas
The AP150 is provided with external antenna ports. Make sure that all external
antennas and their associated wiring are located entirely indoors. The external
antennas are not suitable for outside use.
If the AP150 does not have external antennas, attach the antennas to the connectors
on the AP150 (see Figure 28). Rotate the knurled ring at the base of the antenna
clockwise to attach the antenna. The ring should be finger-tight.
Caution!
knurled ring before moving the antenna. Retighten the ring afterward. Otherwise, you
might damage the internal cabling in the AP.
When changing the orientation of the antennas, be sure to slightly loosen the
Mounting the Access Point
You can mount an AP150 in the following ways:
Horizontally, as described in the “Horizontal Mounting” section.
Vertically, as described in the “Vertical Mounting with the Mounting Bracket”
section.
Below a hanging ceiling, as described in the “Mounting Below a Suspended
Ceiling” section.
Note that the AP300 Power Adaptor can also be used for AP150.
Above a tiled hanging ceiling with the optional ceiling mounting kit.
2. Mark the location on the wall for two mounting screws. They are placed 4.3"
apart, center-to-center, or one above the other. If you are not using plastic wall
anchors, you must either center the mounting screws on a wall stud or use plastic
wall anchors.
3. Drill holes at the locations you marked:
— 3/16-inch holes if you are using plastic anchors
— 1/8-inch holes if you are using only the screws
4. If you are using plastic anchors, install them in the holes.
5. Screw in the screws most of the way, so that the screw head is about 1/16 of an
inch from the wall.
6. Align the AP150 keyholes over the mounting screws and slightly pull down (or
across, if mounting sideways).
7. For external antennas, loosen the knurled ring at the base of each antenna (see
Figure 28), point the antenna straight up, then retighten the ring.
8. Connect one end of the PoE 100BaseT Ethernet cable to the 100/1000 Ethernet
connector, shown in Figure 29.
Vertical Mounting with the Mounting Bracket
The AP150 uses thumbscrews to attach to the mounting bracket or mounting plate
that allows the access point to be mounted on a vertical surface. Additionally, three
shoulder screws may be installed on the mounting bracket to allow the AP150 and
attached bracket to mount over a previously installed Cisco mounting bracket or
Proxim AP4000 bracket.
To vertically mount an AP:
1. If not mounting the AP150 to a previously third-party installed mounting bracket,
use a 1/8” Allen wrench to remove the shoulder screws from the mounting
bracket, if already attached.
2. Using the bracket holes as a template, remove the bracket from the AP150 (or use
the stencil in Appendix , “Mounting Bracket Stencils”) to mark the location on the
wall for the two AP bracket mounting screws. They are placed 4.3 inches apart,
center-to-center. If you are not using plastic wall anchors, you must center the
mounting screws on a wall stud. If you do not center the mounting screws on a
wall stud, you must use plastic wall anchors.
When the AP150 is first connected to the controller and any time the access point is
rebooted thereafter, the AP initializes with and then is programmed by the
controller. The Status LED (see Figure 33) color reflects the various operating states
