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.

AP150

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

This chapter describes how to install and configure an AP300. It contains the following sections:

Safety Precautions

Unpack the AP300

Determine Power Requirements

Installation Requirements

Install the AP300

Check AP300 LED Activity

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 intercon-

nected equipment must be contained within the same building, including the interconnected equip-

ment's associated LAN connection.

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.

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

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.

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 junc-

tion 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-SCRMKIT

Above Suspended Ceiling Mounting Kit (T-Bar Hanger): ACC-MNT-ASCMKIT

Inside a Hoffman Enclosure using Hoffman compatible mounting bracket: ACC-AP300-BHE (enclosure

not provided)

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.

To complete AP300 installation, you need the items listed below.

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.

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.) Meru supplied antennas are suitable

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.

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.

To order this unit, contact your Meru sales representative and refer to part number ACC-ANT-MIMO-MNT.

1. Attach the shorter end of the screw to the center hole on the back of the Antenna Mount.

2. Remove the designated ceiling tile.

3. Using the template, drill holes in the ceiling tile.

4. Replace the ceiling tile.

5. Remove a ceiling tile adjacent to the newly drilled tile for access purposes.

6. Feed the Antenna Mount cable through the larger hole in the ceiling tile until the Antenna Mount

is flush with the ceiling. The screw should now be visible above the ceiling tile (through the second

hole).

7. Place the triangular plate above the ceiling tile with the screw aligned through the plate.

8. Drop the washer onto the screw and tighten the bolt.

The Antenna Mount is now connected to the ceiling.

9. Replace the adjacent tile.

2. Connect the three Remote Antenna Mount cables to the appropriate ports on the AP300. Be sure to

connect the three antennas that correspond to one radio. With dual radio, Radio 1 uses A4, A5, A6

and Radio 2 uses A1, A2, A3. For AP310/AP310-M, the single radio uses A1, A2, A3.

3. Attach three of the antennas that shipped with AP300 to the three ports on the triangular remote

device.

4. 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.

Install External ACC-ANT-MIMO-MNT Antenna with Three Connectors

(optional)

You can optionally use an external antenna setup with your AP300 if the controller and APs are running

System Director 3.6.1MR4 and later. Meru supports this antenna for use on one radio using 802.11n

MIMO. An AP300 with one radio, for example AP310/AP310-M, needs one antenna. An AP300 with two

enO oidaR .sannetna owt sdeen ,023PA elpmaxe cables connect to ports A1, A2, and A3. Radio

Install the Access Point

AP300 ships with a detachable mounting bracket. The AP300 is designed to be compatible with 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:

If you are replacing AP150s, you can use the existing brackets: the AP150 and AP300 use the

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

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.

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.

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

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.

Install the AP300

7. If you are not using a PoE device, connect an external power supply to the power connector and

plug it into the wall.

Mount AP300 Below a Suspended Ceiling

The optional suspended ceiling mounting kit (ACC-MNT-SCRMKIT) allows the AP300 mounting bracket

to attach to suspended ceiling T-rails (see Figure 9).

Note:

To comply with NEC code, attach a grounding wire to any of the screws used to attach the AP300

to the mounting bracket.

Figure 9: Mounting any AP to a Suspended Ceiling Rail using ACC-MNT-SCRMKIT

To mount an AP300 below a suspended ceiling:

1. Determine the location on the ceiling rail where the AP will be mounted and remove the ceiling

tiles.

2. Place each of the two caddy fasteners on the ceiling T-rail and twist to attach to the rail.

3. Adjust the distance between the caddy fasteners by using the mounting bracket holes as a guide.

4. Tighten the caddy fasteners in place using a standard screwdriver. Do not overtighten.

5. Place each spacer on the caddy fastener stud. The spacer legs should contact the ceiling T-rail.

6. Align the mounting bracket keyholes with the caddy fastener studs and slide the AP300 to the

narrow end of the hole.

7. Attach a keps nut to each caddy fastener stud and hand tighten. Do not overtighten.

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.

Mount AP300 Above a Suspended Ceiling (Plenum)

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 T-

bar 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.

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 air-

handling 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.

00232

Install the AP300

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

Install the AP300

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.

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.

Mount AP300 in a Hoffman Enclosure

Meru has designed a custom mounting bracket compatible with a Hoffman enclosure (www.hoffmanon-

line. 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

mounting screws facing downwards.

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.

Note:

Use a shielded Cat 5e (or greater) Ethernet cable in order to comply with

international electromagnetic emissions limits.

Check AP300 LED Activity

Figure 14: Hoffman Bracket ACC-AP300 -BHE

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 initial-

izes and is then programmed by the controller. When the AP first powers up, all LEDs are green.

Chapter 3

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:

Safety Precautions

Unpack the AP320i

Determine Power Requirements

Installation Requirements

Installing AP320i

Check AP320i LED Activity

Where to Go From Here

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 intercon-

nected equipment must be contained within the same building, including the interconnected equip-

ment'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.

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.)

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.

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

Radio 1 MIMO Radio 2 MIMO 802. 3af PoE 802. 3at PoE DC Power

Installation Requirements

802.3at 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/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

Installation Requirements

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.

Installation Type Order These Additional Items

Horizontal mounting None

Vertical mounting over a wall

stud None

Vertical mounting on sheetrock None

Horizontal mounting below a

hanging ceiling None

Reusing an existing bracket from

another AP

For connection to Meru AP200 or AP150 only, order shoulder screws,

Meru part number 665-00012 (SCR, PIC.1/4*1/8 10-32 SKT SHLDR

SCR 303 STNLS). Connection to other brackets does not require this.

Installing AP320i

Select a Location

All AP320i interconnected equipment must be contained within the same building, including the inter-

connected 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 place-

ment with this pattern in mind.

Figure 16: Coverage Pattern for AP320i 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.

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

ceiling

floor

Installing AP320i

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

Installing AP320i

Mount AP320i On a Suspended Ceiling

AP320i ships ready to mount on a suspended ceiling; the attached bracket clips to a ceiling rail.

To mount an AP320i below a suspended ceiling, follow these steps:

1. Determine the location on the ceiling rail where the AP will be mounted and remove the ceiling

tiles.

2. Align the mounting bracket with the slots indicated in Figure 17 below.

Figure 17: Install AP320i Below a Suspended Ceiling

3. Press down on the tab indicated in Figure 17 and rotate the AP320i into place.

4. Connect one end of the CAT5 (or greater) Ethernet cable to the 100/1000 Ethernet connector.

Installing AP320i

Mount AP320i Vertically on a Wall

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.

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

heads and sliding the bracket down.

Selecting a Location

The AP200 requires a location that meets the following:

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)-compat-

ible network switch or PoE power injector installed between the switch and the

AP200.

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

AP200 will be mounted.

Most installations receive the best coverage using the following guidelines:

Install APs toward the center of the building.

Relative to the ground, orient the antenna up or down, not sideways.

The AP200 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.

Attaching the AP200 Antennas

The AP200 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 AP200 does not have external antennas, attach the antennas to the connectors

on the AP200 (see Figure 16). Rotate the knurled ring at the base of the antenna

clockwise to attach the antenna. The ring should be finger-tight.

Mounting the Access Point

You can mount an AP200 in the following ways:

Horizontally, as described in the “Horizontal Mounting” section.

Vertically, as described in the “Vertical Mounting” section.

Below a hanging ceiling, as described in the “Mounting Below a Suspended

Ceiling” section.

Above a tiled hanging ceiling, as described in the “Mounting Above a Suspended

Ceiling” section.

Horizontal Mounting

To horizontally mount an AP200:

1. Place the AP200 flat on the horizontal surface.

2. For each antenna, loosen the knurled ring at the base of the antenna (see

Figure 16), point the antenna straight up, then retighten the ring.

Note:

The previous guidelines are general guidelines. Each site has its own unique

environment. Place access points accordingly.

Caution!

When changing the orientation of the antennas, be sure to slightly loosen the

knurled ring before moving the antenna. Retighten the ring afterward. Otherwise, you

might damage the internal cabling in the AP.

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)-compat-

ible 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.

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.

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.

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.

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.

Note:

The previous guidelines are general guidelines. Each site has its own unique

environment. Place access points accordingly. Note that the AP300 Power Adaptor

can also be used for AP150.

Caution!

When changing the orientation of the antennas, be sure to slightly loosen the

knurled ring before moving the antenna. Retighten the ring afterward. Otherwise, you

might damage the internal cabling in the AP.

Installing the Access Points

Horizontal Mounting

To horizontally mount an AP150:

contractor for advice. Once the required antenna height has been determined, other

factors affecting the precise position of the OAP180 must be considered.

Be sure there are no other radio antennas within 2 m (6 ft.) of the OAP180.

Place the OAP180 away from power and telephone lines.

Avoid placing the OAP180 too close to any metallic, reflective surfaces, such as

roof-installed air-conditioning equipment, tinted windows, wire fences, or water

pipes.

OAP180 has two radios with one antenna per radio, so there is no diversity.

Radio Interference

Avoiding radio interference is an important part of wireless planning. Interference is

caused by other radio transmissions using the same or an adjacent channel frequency.

You should first scan your proposed site using a spectrum analyzer to determine if

there are any strong radio signals using the 802.11a or 802.11bg channel frequencies.

Always use a channel frequency that is furthest away from another signal.

Weather Conditions

Take into account any extreme weather conditions that are known to affect your

location. Consider these factors:

Te m p e r a t u r e — The OAP180 is tested for normal operation in temperatures from

- 40°F to 140°F. Operating in temperatures outside of this range may cause the

unit to fail.

Wind Velocity — The OAP180 can operate in winds up to 44 m/s and survive higher

wind speeds up to 66 m/s. You must consider the known maximum wind velocity

and direction at the site and be sure that any supporting structure, such as a pole,

mast, or tower, is built to withstand this force.

Lightning — The OAP180 includes its own built-in lightning surge protection.

However, you should make sure that the unit, any supporting structure, and cables

are all properly grounded. Additional protection using lightning rods, lightning

arrestors, or surge suppressors may also be employed. Antenna sockets should

point upwards in a vertical manner

Rain — The OAP180 is weatherproofed against rain. Also, prolonged heavy rain has

no significant effect on the radio signal. However, it is recommended to apply

weatherproof sealing tape around the Ethernet port and antenna connectors for

extra protection. If moisture enters a connector, it may cause a degradation in

performance or even a complete failure of the link.

Snow and Ice — Falling snow, like rain, has no significant effect on the radio

signal. However, a build up of snow or ice on antennas may cause the link to fail.

In this case, the snow or ice has to be cleared from the antennas to restore

operation of the link.

Ethernet Cabling

When a suitable antenna location has been determined, plan a cable route from the

OAP180 outdoors to the power injector module indoors. Consider these points:

The Ethernet cable length should never be longer than 100 ft.

Determine a building entry point for the cable.

Determine if conduits, bracing, or other structures are required for safety or

protection of the cable.

For lightning protection at the power injector end of the cable, consider using a

lightning arrestor immediately before the cable enters the building.

The shield of the ethernet cable needs to be grounded at the lightning arrestor.

If, by design, the lightning arrestor cannot provide this ground, the shield of the

ethernet cable will need to be grounded by the installer.

Grounding

It is important that the OAP180, cables, and any supporting structures are properly

grounded. The OAP180 unit includes a grounding screw to attach a ground wire. Be

sure that grounding is available and that it meets local and national electrical codes.

Installing the Access Points

Test Basic Link Operation

Connect Antennas and Ground Wire to OAP180

OAP180 does not ship with any antenna by default. Since customers have different

outdoor applications, we suggest that you choose from the various antenna options

offered by Meru. See the list in Appendix , “AP Accessories” on page 89.

Four antennas are required if diversity is required. You can also use two antennas and

terminate the other two. The OAP180 works both with antennas that attach directly

to the unit and remote antennas. When using antennas that attach to the unit, attach

the antennas before installing the unit. Use the two connectors on the right (5G-1

and 2.4G-1) as indicated in Figure 8. When deploying an OAP180 with a remote

antenna, first mount remote antennas and then connect them to the OAP180.

Follow these steps:

1. Remove the two right-most antenna covers indicated in Figure 8.

2. Mount the external antenna on the same supporting structure as you did the

OAP180, within 3 m (10 ft.) of it, using the bracket supplied in the antenna

package.

3. Connect the antenna to the OAP180’s N-type connector (5G-1 and 2.4G-1) using

the RF coaxial cable provided in the antenna box.

Checking LED Activity

Antenna Gain Recommendations

The OAP180 auto-adjusts the power level sent from the radio to the antenna, so that

the EIRP emitted from the antenna is the value defined by the controller (100mW by

default). You can increase this setting if you are compensating for signal loss from

long inexpensive cables connecting external antennas. (Configure a false/low dBi

antenna gain to trick the radio into supplying more transmit power to that antenna,

which would then make up for the cable loss.) You may also need to decrease the

EIRP from 100mW to 30mW for a device that only transmits at 30mW. The Antenna

Gain values can be changed from the Web UI Configuration>APs>Antenna Properties

view, or from the CLI using the antenna-property command. Determine the appro-

priate gain for your antenna by checking the following chart.

Note:

Occupational/controlled limits apply in situations in which persons are exposed as a

consequence of their employment provided those persons are fully aware of the potential

for exposure and can exercise control over their exposure. Limits for

occupational/controlled exposure also apply in situations when an individual is transient

through a location where occupational/controlled limits apply provided he or she is made

aware of the potential for exposure.

Note:

General population/uncontrolled exposures apply in situations in which the general

public may be exposed, or in which persons that are exposed as a consequence of their

employment may not be fully aware of the potential for exposure or can not exercise

control over their exposure.

The Interference Statement applies to the following APs:

AP150

OAP180

AP201 Rev 2, AP208 Rev 2

FCC Part 15 Statement

This is to certify that the above models are shielded against the generation of

radio interference. Compliance is dependent upon the use of Cat 5e shielded

data cables or a Meru-supplied line filter. Contact Meru Support to obtain a line

filter, free of charge.

AP300 series

Caution!

The radiated output power of the Meru Networks devices is well below the FCC

radio frequency exposure limits. However, the Access Point should be used in

such a manner that the potential for human contact during normal operation is

minimized. When installing and operating these devices, keep a minimum

distance of 20 cm (8 inches) between the antennas and any persons/users in the

vicinity.

USA

Interference Statement

This device complies with Part 15 of the FCC Rules. Operation is subject to the

following two conditions: (1) This device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that

may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B

digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to

provide reasonable protection against harmful interference in a residential installa-

tion. This equipment generates, uses, and can radiate radio frequency energy. If the

equipment is not installed and used in accordance with the instructions, the equip-

ment may cause harmful interference to radio communications. There is no guar-

antee, however, that such interference will not occur in a particular installation. If

this equipment does cause harmful interference to radio or television reception

(which can be determined by turning the equipment off and on), the user is encour-

aged to try to correct the interference by taking one or more of the following

measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from to which the

receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

This device must not be co-located or operating in conjunction with any other

antenna or transmitter.

For products available in the USA and Canadian markets, only channels 1 through 11

can be operated. Selection of other channels is not authorized.

Note:

Meru Access Points

All devices except the OAP180 are indoor devices. The FCC requires indoor use for

the frequency range 5.15 GHz to 5.25 GHz to reduce the potential for harmful

interference to co-channel Mobile Satellite systems.

High-power radars are allocated as primary users of the 5.25 to 5.35 GHz and 5.65

to 5.85 GHz bands. These radar stations can cause interference with or damage to

these devices, or both.

Note:

The Meru Access Point must be installed and used in strict accordance with the

manufacturer’s instructions as described in the user documentation that comes

with the product. Any other installation or use may violate FCC Part 15

regulations. Modifications not expressly approved by Meru Networks, Inc. could

void your authority to operate the equipment.

Canada. Industry Canada (IC)

The Class B digital portion of this apparatus complies with Canadian standard ICES-003.

These devices comply with RSS210 of Industry Canada.

Per RSS 210 A9.5 point 7:

(i) the device for the band 5150-5250 MHz is only for indoor usage to reduce potential for

harmful interference to co-channel mobile satellite systems;

(ii) the maximum antenna gain permitted (for devices in the bands 5250-5350 MHz and 5470-

5725 MHz) to comply with the e.i.r.p. limit; and

(iii) the maximum antenna gain permitted (for devices in the band 5725-5825 MHz) to comply

with the e.i.r.p. limits specified for point-to-point and non point-to-point operation as appro-

priate, as stated in section A9.2(3).

In addition, users should also be cautioned to take note that high-power radars are allocated as

primary users (meaning they have priority) of the bands 5250-5350 MHz and 5650-5850 MHz

and these radars could cause interference and/or damage to LE-LAN devices.

(iv) These devices are not permitted to operate in the 5600 - 5650 MHz band.

For products available in the USA and Canadian markets, only channels 1 through 11 can be

operated. Selection of other channels is not authorized.

Operation is subject to the following two conditions: (1) this device may not cause interfer-

ence, and (2) this device must accept any interference, including interference that may cause

undesired operation of this device.

This device and its listed antenna(s) must not be co-located or operated in conjunction with any

other antenna or transmitter

L’utilisation de ce dispositif est autorisée seulement aux conditions suivantes: (1) il ne doit pas

produire de brouillage et (2) l’utilisateur du dispositif doit étre prêt à accepter tout brouillage

radioélectrique reçu, même si ce brouillage est susceptible de compromettre le fonctionnement

du dispositif.

The term "IC" before the equipment certification number only signifies that the Industry

Canada technical specifications were met.

To reduce the potential radio interference to other users, the antenna type and gain should be

chosen so that the equivalent isotropically radiated power (EIRP) is not more than that required

for successful communication.

To prevent radio interference to the licensed service, this device is intended to be operated

indoors and away from windows to provide maximum shielding. Equipment (or its transmit

antenna) that is installed outdoors is subject to licensing.
