Meru Access Points and Radio Switch

Meru Access Points and Radio Switches contain radio devices that communicate with

the Meru Controller and form the wireless LAN (WLAN). The Meru Controller, Radio

Switches, and Access Points connect to the site’s wired LAN through wired switches.

Wireless clients associate with the Radio Switches and Access Points as they roam

throughout the WLAN. As such, the Meru Wireless LAN System is an extension of the

wired LAN, providing the wireless benefits of client mobility, enhanced access, and

dynamic network configuration.

Meru Access Point AP200 Series

The Meru Access Point AP200 series provides two models that conform to the speci-

fications 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.

zThe AP201 houses a single 802.11a/b/g radio device

zThe 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 the Meru

Controller, providing real-time status of RF activity to optimize the wireless

network.

The Meru Access Point AP200 series (referred hereafter as the AP200, unless specif-

ically referring to the AP201 or AP208) is housed in a metal case with a plastic remov-

able cover. As such, it can be used for plenum installations when the plastic cover is

removed.

Meru Access Point AP150 Series

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 capa-

bilities.

The Meru Access Point AP150 supplies the following features:

zDual 802.11b/g and 802.11a radios

zSimultaneously support for 802.11b, 802.11g, and 802.11a clients

zContention Management for high density of data clients

zBasic VoWLAN QoS support for small density of voice clients

zMultiple ESSIDs with individual security policies to ensure separation of different

user groups or dynamic VLAN assignment per user based on RADIUS credentials

zZero configuration required at the access point; the installation procedure is a

simple plug-n-play

zAutomatic AP discovery, configuration

zIntelligent load balancing of clients

zLayer 2 or 3 connectivity for flexible deployment options

zLocking mechanism secures access point when mounted in public areas

Note:

Meru Access Point AP150 models may have different revisions, but function-

ally they are the same, and all are referred to as the AP150 series. Hereafter

in this document, all AP150 series models are referred to as the AP150.

Radio Switch RS4000

The Radio Switch RS4000 enables high-capacity enterprise-class wireless LAN connec-

tivity with full support of standard 802.11 security and network management

features. Each RS4000 contains four 802.11 radios (two 802.11b/g, two 802.11a) for

high data and voice throughput – an essential requirement for high user-density envi-

ronments with several simultaneous users. Classrooms and convention halls are

typical deployment applications of the Radio Switch. Deploying the Radio Switch is

easy— as with wireless access points, the Radio Switch can be installed wherever

wireless coverage is needed. For large buildings with multiple rooms and floors, more

than one Radio Switch can be installed to cover the desired area. Wireless users can

seamlessly roam from one Radio Switch to another, getting high-capacity WLAN

access throughout the wireless enterprise enabled with multiple Radio Switches. The

RS4000 also balances radio traffic across its RF channels and resolves contention

within each RF channel such that users receive a switched wireless experience with

dedicated bandwidth to execute a variety of applications ranging from web browsing

and VoIP mobility to multimedia streaming.

Internal Use Only—Beta Draft

The RS4000 ships with either a high-gain omni-directional indoor antenna or a 180-

degree directional indoor antenna that aggregates and layers radio transmissions

from each of the built-in radios. The antenna can broadcast every channel available

to blanket the area around the Radio Switch, yet avoid interference and contention.

This simplifies deployment efforts by eliminating the need for additional antennas

for each radio. More importantly, RF channel planning efforts are greatly simplified.

Using the RS4000, wireless users experience the benefits of switching technology on

Wi-Fi—dedicated bandwidth, traffic separation, and multi-service network support.

The RS4000 can be deployed with up to two 802.11b/g and two 802.11a channels

active on the radio interfaces. The 802.11b/g channels must be separated by a

minimum of 8 channels (for example, channels 1 and 9), so the recommended set is

channels 1 and 11, typically. The 802.11a channels must be separated by a minimum

of 80MHz/16 channels for best performance (for example, channels 36 and 52).

Internal Use Only—Beta Draft

The RS4000 works in conjunction with a wideband RF combination omni directional

(WRC/OD) indoor antenna or a 180-degree directional indoor antenna. Only one

antenna is needed for simultaneous operation of all radios of an RS4000 in both the

2.4GHz and 5GHz bands. The antenna must be connected to the Radio Switch using

any one of the low-loss antenna cables provided in the antenna packaging.

The following table lists the key hardware features of the RS4000.

Note:

PoE must be provided on the first Ethernet connector (ETH1); the antenna

cannot operate correctly without that power source. Power to the second

Ethernet connector (ETH2 ) is optional; if not connected, two of the

radios will not operate.

Install the AP300

Select a Location

All AP300 interconnected equipment must be contained within the same building, including the inter-

connected equipment's associated LAN connection. In addition, the AP300 should be mounted in a loca-

tion that meets the following conditions:

zRelatively 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. For an external power supply connection, ensure the power

source is near to where the AP300 will be mounted.

zAccess to wall outlet or a to a Power over Ethernet (PoE) connection to the network switch servicing

the controller.

Most installations receive the best coverage using the following guidelines:

zInstall APs toward the center of the building.

zDo not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.

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

Attach the Antennas

The AP320, AP311, and AP302 have six external antenna ports, labeled 1 - 6. These units only operate

with six attached antennas, even though some configurations don’t use all six. Make sure that all

external antennas and their associated wiring are located entirely indoors. The external antennas are

not suitable for outdoor use. Figure 6 illustrates the recommended antenna configuration.

Note:

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

environment. Place access points accordingly.

Figure 6: AP320, AP311 or AP302 Antennas 1-6

The following antenna connections are used during operation of the AP320, AP311, and AP302.

Table 5: Antenna Use for AP320, AP311, and AP302 (Dual Radio Units)

The AP310 has six external antenna ports labeled 1 - 6. However, AP310 uses a maximum of three

antennas and the unused antenna connectors are blocked. Figure 7 illustrates the recommended

antenna configuration for the AP310.

Install the Optional Remote Antenna Mount on the Ceiling

Use an optional Remote Antenna Mount for one or both AP300 radios to remotely connect the AP300

antennas. The 3*3 SMA Antenna Stand allows you to relocate either your current antennas or the Meru's

High Gain Dipole Antennas to a location with clearer signal paths to the other devices in your wireless

network. The Remote Antenna Mount can be placed 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 needs one unit, and AP320 needs two units.The Antenna

Mount uses low-loss Plenum rated LMR195 cable and SMA connectors.

Figure 9: Remote Antenna Mount

The remote antenna mount kit includes:

zAntenna stand with attached cable. The three antenna SMA female connectors on the Antenna

Mount support AP300 antenna diversity. This feature gives the client the ability to automatically

choose the antenna receiving the strongest signal.

zTriangular ceiling mount clip for attaching to hanging ceiling (includes bolt assembly)

zThree self-adhesive pads for the bottom of the unit (over the screws)

zTwo wall mount screws with anchors

zCeiling Mount Template

zInstallation diagram

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.

To connect the remote antenna mount to the ceiling, refer to the enclosed installation diagram while

following these steps:

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.

10. Connect the three Remote Antenna Mount cables to the appropriate connectors on the AP300. Be

sure to connect the three antennas that correspond to one radio. See Ta ble 5 and Tab le 6 to

determine the cable connection configuration.

11. Attach three antennas that shipped with AP300 to the three connectors on the triangular remote

device. See Figure 9.

Install the Optional Antenna Mount on a Wall

1. Reorient the cable on the Remote Antenna Mount by removing the three screws on the back,

removing the small cover, reorienting the cable and then replacing the three screws. Discard the

small cover.

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

sure to connect the three antennas that correspond to one radio. See Ta ble 5 and Tab le 6 to

determine the cable connection configuration.

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

device. See Figure 9.

Install the Access Point

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

brackets supplied by Meru and by other vendors. The AP300 mounts directly on the AP150 mounting

bracket. If you are replacing AP300s, the AP300 bracket can be mounted on the old AP300 bracket with

included shoulder screws; you don’t need to remove the old brackets. AP300 can also be directly

mounted on third-party brackets. You can mount an AP300 in the following ways:

zMount AP300 Horizontally on a Shelf

zMount AP300 Vertically on a Wall

zMount AP300 Below a Suspended Ceiling

zMount AP300 Above a Suspended Ceiling (Plenum)

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. See Figure 1.

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.

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 the Ethernet cable to the switch and to the AP300 Ethernet port shown in Figure 2.

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 allows the AP300 mounting bracket to attach to suspended

ceiling T-rails (see Figure 10).

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 10: Mounting the AP300 to a Suspended Ceiling Rail

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.

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 10). You should hear it snap

in place.

9. For each antenna, loosen the knurled ring at the base of the antenna (see Figure 8), 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.

Mount AP300 Above a Suspended Ceiling (Plenum)

The optional T-bar box hanger mounting kit allows the AP300 to be mounted above suspended ceiling

T-rails (see Figure 11). The installation attaches the T-bar box hanger to the ceiling rails using clips.

The AP300 attaches to the mounting bracket that is attached to the T-bar box hanger.

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.

Figure 11: AP300 Mounted Above a Suspended Ceiling

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.

Warning!

filter, available at no charge, that may also be used to ensure compliance.

Caution!

Be sure to connect the Ethernet cable to the Ethernet port; the cable can

mistakenly be plugged into the Console port.

Warning!

When installed in air-handling spaces, such as above a suspended ceiling,

the AP200 is to be powered via PoE only (PoE is required).

Warning!

The AP200 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 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).

Selecting a Location

When you plan the OAP180 physical configuration, include the elements shown in this

drawing:

Figure 27: Sample Physical Layout

Radio Position Planning

Never construct a radio mast, pole, or tower near overhead power lines. In addition, local

regulations may limit or prevent construction of a high radio mast or tower. If your

OAP180 link requires a high radio mast or tower, consult a professional contractor for

advice. Once the required antenna height has been determined, other factors affecting

the precise position of the OAP180 must be considered.

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

zPlace the OAP180 away from power and telephone lines.

zAvoid placing the OAP180 too close to any metallic, reflective surfaces, such as roof-

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

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

00196

Installing the Access Points

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 loca-

tion. Consider these factors:

zTem peratu re — 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.

zWind 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.

zLightning — 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

zRain — 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.

zSnow 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:

zThe Ethernet cable length should never be longer than 100 ft.

zDetermine a building entry point for the cable.

zDetermine if conduits, bracing, or other structures are required for safety or protection

of the cable.

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

lightning arrestor immediately before the cable enters the building.

zThe 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.

Installing the Access Points

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.

Test Basic Link Operation

network switch that provides IEEE 802.3af PoE. Always connect the unit to the included

power injector module to maintain the warranty.

Note:

Each AC power injector requires 1.5 amps of power at 100-240 volts. When

connecting multiple devices to one outlet, be sure to allow 1.5 amps for each AC power

adapter.

Installing the Access Points

Follow these steps to connect the power injector:

1. Connect the other end of the provided Ethernet cable (already connected to the

OAP180) to the RJ-45 port labeled Output on the power injector.

2. Connect a straight-through unshielded twisted-pair (UTP) cable (not included) from a

local LAN switch to the RJ-45 port labeled Input on the power injector. See the

illustration above. Use Category 5e or better UTP cable for 10/100BASE-TX

connections.

3. Insert the power cable plug directly into the standard AC receptacle on the power

injector. See the illustration above.

4. Plug the other end of the power cable into a grounded, 3-pin socket, AC power source.

5. Check the LED on top of the power injector to be sure that power is being supplied to

the OAP180 through the Ethernet connection.

Align Antenna

After the OAP180 unit is mounted, connected, and the radios are operating, the anten-

nas must be accurately aligned to ensure optimum performance of the OAP180 links. In

line cord set that has been approved for the receptacle type in your country.

Where to Go From Here

this point-to-multipoint configuration all OAP180 nodes must be aligned with the root

OAP180 antenna.

Where to Go From Here

Now that the OAP180 is installed, go to the Meru System Director Getting Started Guide

for instructions on initializing the controller and connecting the controller and APs to the

Ethernet switch to form the WLAN. Return to this chapter to check the status of the LEDs

once the WLAN is operational.

As well, check the AP chapter in the Meru System Director Configuration Guide for

instructions on configuring radio band, dual radio, and external antenna operation.

Checking LED Activity

Check the OAP180 LEDs for activity. Four of the eight LEDs on the bottom of the OAP180

indicate activity; four LEDs are not used at this time. Check the four active LEDs to deter-

mine if the AP is working.

The grey LEDs in the illustration are not currently used. The following chart explains the

meanings for the remaining LEDs.

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 appropriate gain for your antenna by checking the

following chart.

tion” on page 115 before installing and operating this product.

This product is intended to be supplied by a UL Listed power supply, marked Class 2

or LPS, and rated minimum 5 Vdc, 3A.

Unpacking the AP150

Confirm that the AP150 shipping package contains the AP150 access point with

attached mounting bracket

Caution!

The AP150 is not certified for plenum installations, and should not be

installed in the plenum space.

Installation Requirements

Figure 32: AP150 with Mounting Bracket

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 32) 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 AP150below a

hanging ceiling, using the mounting bracket.

Installation Requirements

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:

zOn a horizontal surface, such as a table or a desk

zOn a vertical surface, usually a wall

zBelow a hanging ceiling

To complete this installation, you need the items listed in Tab le 1 3.

Selecting a Location

The AP150 requires a location that meets the following:

zRelatively unobstructed access to the stations the AP serves

zPower 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.

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.

Installing the Access Points

Most installations receive the best coverage using the following guidelines:

Install APs toward the center of the building.

zDo not install APs near metal objects, such as heating ducts, metal doors, or

electric service panels.

zRelative 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 33). 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:

zHorizontally, as described in the “Horizontal Mounting” section.

zVertically, as described in the “Vertical Mounting with the Mounting Bracket”

section.

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

Ceiling” section.

Horizontal Mounting

To horizontally mount an AP150:

1. Place the AP150 flat on the horizontal surface.

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

Figure 33), 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.

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 1200 mounting 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 C, “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.

About an Hoffman/NEMA Enclosure Installation

The recommended RS4000 installation is a wall mount, but if necessary the RS4000

can be housed inside a protective NEMA or Hoffman box that is manufactured with

external corner tabs for standard wall mounting, above or below a ceiling. When

installing in the Hoffman/NEMA box, the RS4000 attaches to an optional

Hoffman/NEMA box mounting plate, which replaces the standard wall mount bracket.

Meru leaves the placement and orientation of the Hoffman/NEMA enclosure to the

customer. It will be necessary to drill holes through the plastic NEMA enclosure with

a Meru-provided template to enable the antenna and Ethernet cabling to exit the

enclosure. Instructions for performing this task are provided in the section “Creating

Warning!

Inside antennas must be positioned to observe minimum separation of 20

cm. (~ 8 in.) from all users and bystanders. For the protection of personnel working

in the vicinity of inside (downlink) antennas, the following guidelines for minimum

distances between the human body and the antenna must be observed.

The installation of the indoor antenna must be such that, under normal conditions,

all personnel cannot come within 20 cm. (~ 8.0 in.) from any inside antenna.

Exceeding this minimum separation will ensure that the employee or bystander does

not receive RF-exposure beyond the Maximum Permissible Exposure according to FCC

CFR 47, section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.

Figure 52: Antenna Ceiling Tile Rail Base

The RS4000 antenna uses two RF cables (3-foot cables are supplied) to connect to the

SMA connectors on the top panel of the RS4000 (see Figure 43). The RF cables should

be attached to the RS4000 as a result of the procedures described in one of the

previous installation procedures.

Mount the antenna and connect the cables as described in the following:

1. Choose whether to hang the arm on a wall (including solid ceiling wall) or ceiling

tile rail.

—For wall or ceiling mount:

a. Using the screwholes in the mounting bracket as a template, mark and drill holes

into the wall.

b. Attach the bracket securely with three 1/4" diameter fasteners or one 5/16"

diameter and one 1/4" diameter fastener, if mounting to a wall stud (fasteners

are not supplied).

—For ceiling tile rail mount:

a. Pull apart the rail clamps so the ears can fit over the width of the ceiling rail.

b. Squeeze the rail clamp to attach to the ceiling rail.

2. Connect the RF antenna wires from the RS4000 to the SMA connectors on the top

of the antenna, using Figure 43 or Figure 50 for orientation.

3. Attach the top of the antenna to the 1/4-20 threaded stud on the swivel head and

tighten against the antenna.

4. For a 180o directional antenna, position the antenna such that the logo on the top

of the antenna is pointing in the direction where reception is required.

5. Loosen the angle adjusting lever on the swivel assembly, if necessary, to adjust

the hanging angle.

6. Position the antenna to maximize the reception and tighten the adjusting lever.

Hoffman/NEMA Enclosure RS4000 Installation

Use the procedures in this section to mount the RS4000 within the Hoffman or NEMA

enclosure. It will be necessary to modify the NEMA enclosure by drilling cable pass-

through holes before installing the RS4000.

Creating Cable Pass-through Holes in the NEMA Enclosure

To create cable pass-through holes in the NEMA enclosure, Meru supplies a template

with markings that coincide with the placement of the Ethernet and antenna cable

locations on the RS4000. Depending on the orientation of the RS4000 installation in

the NEMA enclosure, the template is to be used on the side of the enclosure adjacent

to the RS4000 top panel, where the cables connect.

1. Open the lid of the empty NEMA enclosure to provide unimpeded access to the

enclosure sides.

2. On the outside of the empty NEMA enclosure, locate the top center of the side

where the cables will exit.

3. Using the pattern on the supplied template, mark the center of the holes and drill

a 1/2" to 1" hole at each of the three locations specified by the template.

Note:

The recommended Meru installation is a vertical wall mount, which allows for

unimpeded air flow through the unit. The option to install the RS4000 within a

Hoffman/NEMA enclosure is left to the customer’s discretion, based on site-specific

factors such as protection and accessibility, etc. Installation in the Hoffman

enclosure requires drilling air vents and cable pass-through holes.

Installing the RS4000

Mounting the RS4000 in the Hoffman/NEMA Enclosure

To mount the RS4000 in the Hoffman/NEMA enclosure, it is necessary to use the

optional mounting plate that is not supplied with the RS4000 packing items. This

procedure assumes the Hoffman/NEMA enclosure is already mounted at the site.

1. Remove the wall bracket from back of the RS4000, if attached, by unscrewing

each of the 4 knurled thumbscrews.

2. Attach the Hoffman/NEMA mounting plate to the back of the RS4000.

3. Attach the right-angle elbow joint to the antenna cable, if not already attached.

4. Attach the two antenna cables to the SMA antenna connectors labeled ANT1 and

ANT2 on the top panel of the RS4000 (see Figure 43) by turning the cable ends

clockwise until tight.

5. Attach two Ethernet cables to the Ethernet ports labeled ETH1 and ETH2 on the

top panel of the RS4000.

6. Place the RS4000 into the Hoffman/NEMA enclosure, and align the plate

screwholes with the holes in the Hoffman/NEMA enclosure.

7. Pass the Ethernet and antenna cables out of the Hoffman/NEMA enclosure through

the cable pass-through holes.

8. Tighten the captive screws on the mounting plate to the Hoffman/NEMA

enclosure.

9. Attach the antenna cables to the antenna (see Figure 50).

10. Position and align the bottom of the antenna over the threaded stud on the

antenna mount arm and tighten the threaded stud to the antenna.
