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 AP
Introducing the Radio Switch RS4000
The Radio Switch RS4000 enables high-capacity enterprise-class wireless LAN connectivity 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 environments with several simultaneous users. Classrooms and convention halls are
typical deployment applications of the Radio Switch. Deploying the Radio Switch is

Meru Access Points and Radio Switch
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 180degree 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.
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.
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.

Installation Requirements
The RS4000 obtains power from 802.3af standard Power over Ethernet (PoE)-compatible 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:
z Do not install the antenna near metal objects, such as heating ducts, metal doors,
or electric service panels.
z Relative to the ground, orient the antenna up or down, not sideways.
Note: The previous guidelines are general guidelines. Each site has its own unique
environment. Place antenna accordingly.
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.

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.
Caution! This method of mounting has not been evaluated by Underwriters

Optimum Antenna Positioning and Placement
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.

Wall Mounting the RS4000
The RS4000 can be mounted to any type of solid wall (including ceiling walls) using
the supplied wall mount bracket. The bracket also allows for junction box mounting.
Note: The RS4000 has a security cable slot so you can secure the RS4000 with a
standard security cable (for example, Kensington cable locks), such as are used to
secure laptop computers.
To wall mount an RS4000:
1. Remove the bracket from back side the RS4000, if it is attached, by unscrewing
each of the 4 knurled thumbscrews (see Figure 6).

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.
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.
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.

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 passthrough holes before installing the RS4000.
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.
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.

Installing the Access Points
Selecting a Location
The AP200 requires a location that meets the following:
z Relatively unobstructed access to the stations the AP serves
z Power over Ethernet (PoE) connection to the network switch servicing the
controller.
APs can obtain their power from 802.3af standard Power over Ethernet (PoE)-compatible network switch or PoE power injector installed between the switch and the
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.
34
Meru Access Point and Radio Switch Installation Guide
© 2007 Meru Networks, Inc.
Installing the Access Points
Most installations receive the best coverage using the following guidelines:
Install APs toward the center of the building.
z Do not install APs near metal objects, such as heating ducts, metal doors, or
electric service panels.
z Relative to the ground, orient the antenna up or down, not sideways.
Note: The previous guidelines are general guidelines. Each site has its own unique
environment. Place access points accordingly.
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.
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.
Mounting the Access Point
You can mount an AP200 in the following ways:
z Horizontally, as described in the “Horizontal Mounting” section.
z Vertically, as described in the “Vertical Mounting” section.
z Below a hanging ceiling, as described in the “Mounting Below a Suspended

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.

Installing the Access Points
Selecting a Location
The AP150 requires a location that meets the following:
z Relatively unobstructed access to the stations the AP serves
z Power over Ethernet (PoE) connection to the network switch servicing the
controller.
APs can obtain their power from 802.3af standard Power over Ethernet (PoE)-compatible network switch or PoE power injector installed between the switch and the
AP150.
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.
50
Meru Access Point and Radio Switch Installation Guide
© 2007 Meru Networks, Inc.
Installing the Access Points
Most installations receive the best coverage using the following guidelines:
Install APs toward the center of the building.
z Do not install APs near metal objects, such as heating ducts, metal doors, or
electric service panels.
z Relative to the ground, orient the antenna up or down, not sideways.
Note: The previous guidelines are general guidelines. Each site has its own unique
environment. Place access points accordingly.
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.
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.
Mounting the Access Point
You can mount an AP150 in the following ways:
z Horizontally, as described in the “Horizontal Mounting” section.
z Vertically, as described in the “Vertical Mounting with the Mounting Bracket”
section.
z Below 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.

Installing the Access Points
4. If you are using plastic anchors, install them in the holes.
5. Screw in the screws most of the way, so that the screw head is about 1/16 of an
inch from the wall.
6. Align the AP150 keyholes over the mounting screws and slightly pull down (or
across, if mounting sideways).
7. For external antennas, loosen the knurled ring at the base of each antenna (see
Figure 33), point the antenna straight up, then retighten the ring.
8. Connect one end of the PoE 100BaseT Ethernet cable to the 100/1000 Ethernet
connector, shown in Figure 34.
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 installed third-party 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.
