Access Points

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.

AP200
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.

Best Practices for an AP300/AP200 Network

Best Practices for an AP300/AP200 Network
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.
Supported Scenario AP200 Configuration AP300 Configuration
Two Unique ESS profiles
AP200 and AP300 SSID string over the air
Unsupported Scenario AP200 Configuration AP300 Configuration
Same ESS profiles
AP200 and AP300 SSID string over the air
Assumptions for the above best practices include:
AP200 is using Virtual Port and BSSID Virtual Cell (AP200 could also be using Shared BSSID Virtual
Cell.)
AP300 is using Virtual Port BSSID 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.)

Determine Power Requirements

Determine Power Requirements
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.
Radio 1 MIMO Radio 2 MIMO 802.3af PoE 802.3at PoE DC Power


Recommend
with caution

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 radioDual 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 radio2x2 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 radioDual 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.
14 Meru Access Point Installation Guide © 2010 Meru Networks, Inc.

Installation Requirements

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:
Suspended Ceiling Rail Mounting Kit: ACC-MNT-SCRMKITAbove Suspended Ceiling Mounting Kit (T-Bar Hanger): ACC-MNT-ASCMKITInside a Hoffman Enclosure using Hoffman compatible mounting bracket: ACC-AP300-BHE (enclosure

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 a Power 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.

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

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.

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).

Installing AP320i

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:

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.

Best Practices for an AP320i/AP200 Network

Best Practices for an AP320i/AP200 Network
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.
Supported Scenario AP200 Configuration AP320i Configuration
Two Unique ESS profiles
AP200 and AP320i SSID string over the air
Unsupported Scenario AP200 Configuration AP320i Configuration
Same ESS profiles
AP200 and AP320i SSID string over the air
Assumptions for the above best practices include:
AP200 is using Virtual Port with BSSID Virtual Cell (AP200 could also be using Shared BSSID Virtual
Cell.)
AP320i is using Virtual Port with BSSID Virtual Cell.AP200s and AP300s are on the same channel. (AP200 and AP320i could also be on different
channels.)
AP200s and AP320i is are on the same controller. (AP200 and AP320i could also be on different
controllers as long as each controller has a unique controller index.)

Determine Power Requirements

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 radioDual 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 radio2x2 for the 2.4 GHz radio

802.3at Usage

When using System Director 3.6/4.0 and 802.3at, the following radio combinations are recommended:
Single 3x3 radioDual 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

Installing AP320i

Installing AP320i

Select a Location

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 a Power 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

Installation Requirements
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.

Selecting a Location

The AP150 requires a location that meets the following criteria:
Relatively unobstructed access to the stations the AP servesPower 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.
© 2010 Meru Networks, Inc. Installing AP150 75
Installing the Access Points
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”
