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.

Safety Precautions

Chapter 2

Installing AP300

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  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.

Warning!

The AP300 is intended only 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.

This product is intended to be supplied by a UL Listed power supply marked Class 2 or LPS and rated minimum 5Vdc, 3A.

Best Practices for an AP300/AP1000 Network

Read this section if you have both AP1000 and AP320i active simultaneously on the same network. The following best practices should be followed to get optimal performance from such a mixed network.

 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.

 If pos sib l e , d o n o t d e p l o y A P 1 0 0 0 and AP3 00/AP320i a t t h e s a m e p h y sic a l l o c a t i o n ; w e r e c o m m end

that there be no overlapping coverage between AP1000 and AP300.

 If AP1000 and AP300/AP320i do have overlapping coverage, you have two options. Deploy them on

seperate channels or make sure the ESS profiles on both AP types are unique. The chart below shows two ESS scenarios, one supported, one not supported.

Supported ESS Scenario AP1000 Configuration AP320i Configuration

Two Unique ESS profiles

AP1000 and AP320i SSID string over the air

Unsupported ESS Scenario AP1000 Configuration AP320i Configuration

Same ESS profiles

AP1000 and AP320i SSID string over the air

Assumptions for the above best practices include:

 AP1000 is using Virtual Port with BSSID Virtual Cell.  AP320i is using Virtual Po rt with BSSID Virtual Cell.  AP1000s and AP300s are on the same channel. (AP1000 and AP320i could also be on different

channels.)

 AP1000s and AP320i is are on the same controller. (AP1000 and AP320i could also be on different

controllers as long as each controller has a unique controller index.)

802.af PoE Usage

When using System Director 3.6/4.0/4.1 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 3.6/4.0/4.1 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

Installation Requirements

 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

For a list of supported PoEs, see the appendix Supported Power Over Ethernet Devices for Meru APs

Installation Requirements

An array of holes on the mounting bracket allows the AP300 to be mounted on the wall and over junction boxes or molly bolts. There are holes for passing the PoE Ethernet or external power supply cable through the bracket if the bracket is mounted on a junction box.

The AP300 has a security cable slot so you can lock the AP300 with a standard security ca ble, 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

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:

 R elatively unobstructed access to the stations the AP serves. Se lect 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.

floor

Install the AP300

 Access to wall outlet or a to a Power over Ethernet (P oE) connection to the network switch servicing

the controller.

 We recommend planning for about 50 clients per radio (or per interference region) if you plan to

use Virtual Port and plan to have phones as clients. For a data-onl y installation, plan up to 128 clients per radio, meaning 256 for AP320 and 128 for other AP300 models. Refer to the Meru Deployment Guides on the support site for more information.

AP300 is designed to provide 360 degree omni-directional coverage as illustrated below. Plan placement with this pattern in mind.

Figure 4: 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 i nstall APs near metal objects, such as heating ducts, metal door s, or electric service panels.  For best coverage, orient antennas as shown in Figure 6.

Attach the Provided Antennas

All AP300s have six external antenna ports, labeled 1 - 6. These units operate with six antennas attached, even though some configurations don’t use all six. Instead of attaching an antenna, you can cap unused antenna connectors with 50 ohm Reverse Polarity SMA terminators. (For a list of approved terminators, see http://www.merunetworks.com/merusupport only for indoor use unless they are mounted in an outdoor enclosure (see Mount AP300 in a Hoffman

Enclosure). To achieve the best performance from your AP300, position antennas at a 90 degree angle

relative to each other as shown in Figure 6. The antennas do not have to be oriented exactly as shown in the figure, but it is important to maintain the relative angles. If for some reason you are unable to maintain those angles, the network still operates, but you may experience up to 20% drop in throughput depending on the antenna orientation.

Install the AP300

Install the Remote Antenna Mount (optional)

Use the optional Meru Remote Antenna Mount (ACC-ANT-MIMO-MN T) 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 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.

Install the Remote 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 R emote Antenna Mount cables to the appropriate ports on the AP300. Be sure to connect the three antennas that correspond to one radio. Radio 1 uses A1, A2, A3 and Radio 2 uses A4, A5, A6. PSM3x devices only utilize A1, A2, A3, and A5.

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 the AP300

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, needs one antenna. An AP300 with two radios, for example AP320, needs two antennas. Radio One antenna cables connect to ports A1, A2, and A3. Radio Two cables connect to ports A4, A5, and A6. There is no preferred cabling connection; all three cables are the same.

Calculate the antenna gain for the ACC-ANT-MIMO-MNT antenna by referring to the next three charts:

You can optionally use an external antenna setup with your AP300 if the controller and APs are running System Director 3.6.1MR4 or 4.0.

When deploying an AP300 with only one antenna per radio, AP300 cannot support 802.11 n MIMO operation. Also, any antenna ports that are not used to connect to an antenna must be terminated with 50 ohm Reverse Polarity SMA terminators. (For a list of approved terminators, see http://www.merunetworks.com/merusupport.) Connect the antenna using one cable per radio as described in the table below. These instructions can be used to replace an AP200 existing antenna configuration with an AP300. For these instructions, each port on the AP300 is identified by a label A1 to A6.

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

Note:

same bracket. If you are replacing AP300s, the AP300 bracket can be attached to the old bracket with included shoulder screws; you don’t have to remove the old brackets. This bracket will also mount seamlessly into the Proxim AP4000 bracket and standard Cisco brackets.

To mount an AP300 on a wal l:

1. Using the bracket holes as a guide, mark the location on the wall for the two AP bracket mounting

2. Drill holes at the locations you marked:

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

4. Screw in the screws most of the way.

5. Mount the bracket on the screws, placing the ci rcular portion of the keyhole mounts over the screw

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

screws. If possible, center the mounting screws on a wall stud. If you do not center the mounting screws on a wall stud, use plastic wall anchors. Orient the AP300 horizontally so that you can read the Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO performance.

Installing AP320i

AP320i is supported by System Director versions 3.6.1 and greater, but full support begins with System Director release 4.x and later. 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  Best Practices for an AP320i/AP1000 Network  Unpack the AP320i  Determine Power 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.

Warning!

The AP320i is only intended for installatio n 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.

This product is intended to be supplied by a UL Listed power supply marked Class 2 or LPS and rated minimum 5Vdc, 3A.

Best Practices for an AP320i/AP1000 Network

Read this section if you have both AP1000 and AP320i active simultaneously on the same network. The following best practices should be followed to get optimal performance from such a mixed network.

 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.

 If possible, do not deploy AP1000 and AP320i at the same physical location; we recommend that

there be no overlapping coverage between AP1000 and AP300.

 If AP 1000 and A P 3 20 i do have overlappi ng coverage, you have two options. De ploy them on seperate

channels or make sure the ESS profiles on both AP types are unique. The chart below shows two ESS scenarios, one supported, one not supported.

Supported ESS Scenario AP1000 Configuration AP320i Configuration

Two Unique ESS profiles

AP1000 and AP320i SSID string over the air

Unsupported ESS Scenario AP1000 Configuration AP320i Configuration

Same ESS profiles

AP1000 and AP320i SSID string over the air

Assumptions for the above best practices include:

 AP1000 is using Virtual Port with BSSID Virtual Cell.  AP320i is using Virtual Po rt with BSSID Virtual Cell.  AP1000s and AP320is are on the same channel. (AP1000 and AP320i could also be on different

channels.)

 AP1000s and AP320i is are on the same controller. (AP1000 and AP320i could also be on different

controllers as long as each controller has a unique controller index.)

Installing AP320i

Select a Location

All AP320i interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection. Ceiling mounting is recommended but wall mounting is also supported. In addition, the AP320i should be mounted in a location that meets the following conditions:

 R elatively unobstructed access to the stations the AP serves. Se lect 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 AP320i horizontally so that you can read the Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO performance.

 We recommend planning for about 50 clients per radio (or per interference region) if you plan to

use Virtual Port and plan to have phones as clients. For a data-onl y installation, plan up to 128 clients per radio, meaning 256 for AP320i. Refer to the Meru Deployment Guides on the support site for more information.

 Access to wall outlet or a to a Power over Ethernet (P oE) connection to the network switch servicing

the controller.

AP320i is designed to provide 180 degree omni-directional coverage as illustrated below. Plan placement with this pattern in mind.

Figure 14: Coverage Pattern for AP320i When Ceiling Mounted

Figure 17: Optionally Install Your Own Lock on AP320i

Mount AP320i Above a Suspended Ceiling

Note:

AP320i is not plenum-rated and should only be mounted above ceilings in non-plenum air space, such as a return airflow for air conditioning.

Installing AP320i

Use the optional T-bar box hanger mounting kit to mount AP320i above suspended ceiling T-rails. The installation attaches the T-bar box hanger to the ceiling rails and then the AP320i attaches to the Tbar box hanger. Note that AP320i mounted above the ceiling has about 2-3 dBm less RF coverage than AP320i mounted under the ceiling.

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 AP320i only with a PoE, not a power supply. See Power Supplies for part numbers.

To mount an AP 320i above the c eiling with th e 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.

3. Attach the mounting bar (depicted in Figure 18) to the mounting brace (which looks like a small

handle) with the crossbar of the mounting kit sandwiched between them. See Figure 19.

4. Gently press the bracket attached to the AP320i against the mounting brace and rotate it into place until the locking mechanism clicks. Note that this is essentially the same process as depicted in

Figure 21.

5. Remove a nut from each leg of the T-Bar kit and slide the crossbar on top of them.

6. Replace the nuts removed to lock the crossbar into place on the legs.

7. Attach the clips on either side of the T-Bar kit to the ceiling tile rails on which the full setup is to

be mounted.

8. Connect a drop wire to a building structural element and through the hole provided in the bracket mounting clip (on the underside of the AP320). The U.S. National Electrical Safety Code requires this additional support.

9. Connect one end of the PoE Ethernet cable to the Ethernet connector.

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 that the AP320i is operating correctly before replacing the ceiling tile to the ceiling. Verify correct operation using the LEDs, as shown in Check AP320i LED Activity.

ACC-MNT-SCRMKIT-03

Mount AP320i Below a Recessed Ceiling

The optional recessed ceiling mounting kit allows the AP320i mounting bracket (which is attached to the AP when it is shipped) to be attached to a recessed ceiling rail by extending the distance from the rail to the AP. This kit can be adjusted to fit either a wide or thin rail size.

The recessed ceiling mounting kit is part number ACC-MNT -SCRMKIT -02 prior to AP revision N. As of revision N, however, the AP ships with a slightly

Note:

Figure 20: ACC-MNT-SCRMKIT-02 and -03

different mounting bracket and utilizes ACC-MNT-SCR MKIT-03 for rece ssed mounting. Be sure to order the correct part number as associated with your AP revision. Refer to Figure 20 for examples.

To mount AP320i below a recessed ceiling, follow these steps:

1. Determine the width of the ceiling rail to be used. This will tell you whether you need to adjust the extender bracket. If the ceiling rail is wider (23.8mm), you do not have to adjust anything; continue to step 3.

2. For a narrow ceiling rail (22.2mm), adjust the bracket. Remove the two screws shown in Figure 20 and flip one side over. This will result in a narrower channel. Tighten the screws.

3. Attach the bracket to the AP by rotating it into place as shown in Figure 21.

Mount AP320i on an Interlude/Silhouette T-Bar

The optional mounting kit for ceilings with Interlude / Silhouette T-bar (ACC-MNT-SCRMKIT-04) allows the AP320i (as of Revision N) to attach to this type of ceiling by extending the distance from the ceiling rail to the AP. See Figure 23.

Installing AP320i

Figure 23: Interlude Tile Bracket

Note:

The mounting procedure for the interlude bracket is identical to that described in Mount AP320i Below

a Recessed Ceiling. Essentially, fit the bracket to the ceiling T-bar and twist the AP into place on it.

Refer to the previous section for step-by-step instructions.

The interlude mounting bracket can only be used for APs post-revision N.

Mount AP320i Vertically on a Wall

Note that your AP320i may utilize one of two different wall mount brackets (depending on the product revision). Prior to revision N, the bracket twisted into position with the AP (shown in Figure 24). The updated bracket (post revision N) slides into place with three mounting screws. For the former bracket, follow the instructions below. For the updated version, refer to Using the Updated AP320i Wall Mount

Bracket.

The AP320i ships with a ceiling mount br acket 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 A P200, the AP320i wall bracket can be mounted on top of the old bracket us ing shoulder screws (not included); you don’t need to remove the old bracket. If you are replacing an AP150 or AP300, the AP320i can also be mounted on top of the old bracket after removing the ceiling mount bracket that ships attached by default (no additional screws required).

To mount an AP320i o n 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 AP320i horizontally so that you can read the Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO performance.

marked Class 2 or LPS and rated minimum 12Vdc, 2A. For Power over Ethernet, an 802.3at connection must be used.

Unpack the AP332e

Confirm that the AP332e shipping package contains these items:

Installation Requirements

 AP332e  Wall mount bracket  Two ceiling mount brackets (for varying sized ceiling structures)  Six antennas  Screws for the mounting bracket

Installation Requirements

An array of holes on the mounting bracket allows the AP332e to be mounted on the wall and over junction boxes or molly bolts. There are holes for passing the PoE Ethernet or external power supply cable through the bracket if the bracket is mounted on a junction box.

The AP332e has a security cable slot so you can lock the AP332e with a standard security cable, such as those used to secure laptop computers.

The AP332e ships with included ceiling and wall mounting brackets to be used for varying types o f lcations, such as on T-bars or over junction boxes. For mounting above ceiling tiles, purchase optional mounting kits:

 Above Suspended Ceiling Mounting Kit (T-Bar Hanger): ACC-MNT-ASCMKIT  Above hanging ceiling tiles. Suitable for use in environmental air space in accordance with the

Section 332e-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. Note that in order to comply with these standards, the plastic cover on the AP must be removed.

Additional Equipment

A power source is needed to power the AP332e. The AP332e requires an 802.3at power source when operating with PoE. If this is not available, 12V DC power (2A rated) must be supplied.

Attach the Provided Antennas

All AP332es 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 from your AP332e, position antennas at a 90 degree angle relative to each other. 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.

The attached antennas must be the same model; if you replace one antenna, replace them all.

 Safety Precautions  Unpack the AP332i  Installing AP332i  Check AP332i 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.

This product is intended to be supplied by a UL Listed power supply

Warning!

The AP332i is only intended for installatio n 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.

marked Class 2 or LPS and rated minimum 12Vdc, 2A. For Power over Ethernet, an 802.3at connection must be used.

Unpack the AP332i

Confirm that the shipping box contains the following:

 AP332i

Installing AP332i

ceiling

floor



Wall mount bracket

 Two ceiling mount brackets (for varying sized ceiling structures)  Screws for the mounting bracket  12V power adapter

Additional Equipment

A power source is needed to power the AP332i. The AP332i requires an 802.3at power source when operating with PoE. If this is not available, 12V DC power (2A rated) must be supplied.

Installing AP332i

Select a Location

All AP332i interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection. Ceiling mounting is recommended but wall mounting is also supported. In addition, the AP332i should be mounted in a location that meets the following conditions:

 R elatively unobstructed access to the stations the AP serves. Se lect 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 AP332i horizontally so that you can read the Meru logo without tilting your head at 90 degrees - this orientation provides optimum MIMO performance.

 We recommend planning for about 50 clients per radio (or per interference region) if you plan to

use Virtual Port and plan to have phones as clients. For a data-onl y installation, plan up to 128 clients per radio, meaning 256 for AP332i. Refer to the Meru Deployment G uides on the support site for more information.

 Access to wall outlet or a to a Power over Ethernet (P oE) connection to the network switch servicing

the controller.

AP332i is designed to provide 180 degree omni-directional coverage as illustrated below. Plan placement with this pattern in mind.

Figure 43: Coverage Pattern for AP332i When Ceiling Mounted

Installing AP332i

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 i nstall APs near metal objects, such as heating ducts, metal door s, or electric service panels.  If you install AP332i on a pole , keep in m ind th at co verag e will be 18 0 deg rees . Do n ot mo unt tw o

AP332is 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

Warnings

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 P ermissible Exposur e according to FCC CFR 47, section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.

Achtung!

Innenantennen müssen so positioniert werden, dass ein Mindestabstand von 20 cm (ca. 8 Zoll) zu allen Benutzern und anderen Personen gewahrt wird. Zum Schutz von Personal, das in der Nähe von Innenantennen (Downlink) arbeitet, sind die folgenden Richtlinien für Mindestabstand zwischen dem menschlichen Körper und der Antenne zu beachten.

Die Innenantenne muss so installiert werden, dass sich unter normalen Bedingungen kein Personal bis auf weniger als 20 cm (ca. 8 Zoll) an eine Innenantenne annähern kann. Durch Überschreitung dieses Mindestabstands wird sichergestellt, dass Mitarbeiter oder andere Personen keiner RF-Exposition über die maximal zulässige Exposition (MPE; Maximum Permissible Exposure) gemäß FCC CFR 47, Abschnitt 1.1310 (Grenzwerte für die allgemeine Bevölkerung/unkontrollierte Exposition) ausgesetzt werden.

Avertissement

Les antennes intérieures doivent être positionnées de façon à respecter une distance minimum de 20 cm par rapport aux utilisateurs et aux tiers. Pour la protection du personnel travaillant à proximité des antennes intérieures (liaison descendante), respecter les directives suivantes pour assurer des distances minimales entre les êtres humains et les antennes.

Toute antenne intérieure doit être installée de telle sorte que, dans des conditions normales, le personnel ne puisse s'en approcher à moins de 20 cm. Cette distance minimale est destinée à garantir qu'un employé ou un tiers ne sera pas exposé à un rayonnement radioélectrique supérieur à la valeur maximale autorisée, telle qu'elle est définie dans les limites d'exp osition non contrôlées pour la population par la réglementation de la FCC CFR 47, section 1.1310.

Advertencia

Las antenas interiores deben colocarse de manera que se observe una separación mínima de 20 cm. (~ 8 pulg.) respecto a todos los usuarios y circunstantes. Para la protección del personal que trabaje en las inmediaciones de las antenas interiores (receptoras), deben observarse las siguientes directrices relativas a la distancia mínima entre el cuerpo humano y la antena.

La instalación de la antena interior debe efectuarse de tal modo que, en condiciones normales, ningún miembro del personal pueda acercarse a menos de 20 cm. (~ 8,0 pulg.) de cualquier antena interior. El cumplimiento de este mínimo de separación asegura que el empleado o circunstante no recibirá exposición a radiofrecuencia por encima de la Exposición Máxima Permisible conforme a la normativa FCC CFR 47, sección 1.1310, es decir, los límites asignados a la Exposición Incontrolada /P oblación Civil.
