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.

Introducing the 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

Meru AP

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.

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).

RS4000 Hardware Features and Specifications

The RS4000 has four 802.11 radios (two 802.11a and two 802.11bg) that transmit and

receive simultaneously on four different channels to increase the total available

wireless bandwidth at a given area. The RS4000 connects to the LAN using one 10/100

Mbps Ethernet connection for each radio pair. The RS4000 is powered using two IEEE

802.3af POE connections, each with 15W power.

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.

Introducing the 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.

Installation Requirements

The RS4000 obtains power from 802.3af standard Power over Ethernet (PoE)-compat-

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

RS4000. At least one PoE connection must be connected.

Select a location with minimal physical obstructions between the RS4000 antenna

and the wireless stations. In many cases, mounting the RS4000 antenna on the wall

near the ceiling provides the least obstructed communications path.

Most installations receive the best coverage using the following guidelines:

zDo not install the antenna 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 RS4000 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.

Note:

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

environment. Place antenna accordingly.

Installation Requirements

You need the tools listed in Tab le 2 .

Table 2: RS4000 Installation Tools

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.

2. Choose the location on the wall where the RS4000 will be mounted. The RS4000

can be oriented in any direction, but it is probably more convenient if the SMA

antenna mounts are at the top. This orientation is more convenient for reading

LED status.

3. Using the bracket holes as a template, mark the location on the wall for the two

RS4000 bracket mounting screws. They are placed 5 25/32" (147mm) apart,

center-to-center, one above the other. If you are not using plastic wall anchors,

you must center the mounting screws on a wall stud.

4. 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

5. If you are using plastic anchors, install them in the holes.

Note:

The RS4000 mounting bracket provides holes to accommodate many types of

common installations such as over a junction box, etc. This procedure describes only

the standard wall mount.

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 8) 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 15).

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.

Selecting a Location

The AP200 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

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.

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 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 21). 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:

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

zVertically, as described in the “Vertical Mounting” section.

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

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.

00177

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 8 .

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 D, “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.
