Determine Power Requirements

Your power requirements will vary, depending on which AP300 radios are deployed and what

mode is used. See Table 2.

Table 2: AP300 Power Options

Installation Requirements

The AP300 standard mounting bracket can be removed. The AP300 is also designed to be used

with brackets supplied by other vendors; if you use a bracket other than an AP150 bracket

(which is identical), you need to obtain three shoulder screws (see Appendix A). Meru APs can

be mounted on Cisco 1230 series brackets, but the Cisco 1240 and 1250 series brackets are new

and not compatible with the Meru bracket.

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

such as those used to secure laptop computers. See Figure 3.

Table 4: AP300 Installation Tools

Additional Equipment

A power source is provided with the AP300. If you want to use a PoE, you need to provide one

of the following:

z802.3af compliant PoE device (for 2x2 mode)

z802.3at compliant PoE device (needed for 3x3 mode)

Install the Access Points

Select a Location

The AP300 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 inter-

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

in a location 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 testing is not complete at this time) 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.

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 AP300 Antennas

The AP300 has six external antenna ports, labeled 1 - 6. AP320 and AP311 use all six antennas.

AP310 uses three antennas (1 - 3). Make sure that all external antennas and their associated

wiring are located entirely indoors. The external antennas are not suitable for outside use.

Figure 4: AP320 Antennas 1-6

Attach Standard Antennas

All standard attached antennas must be the same model. If you replace one antenna, replace

them all. These antennas are supported:

zAntenna Standard multiband, omni-directional white antenna (included)

zStandard Antenna Gain ~ 2.2 dBi for 2.4 GHz,and 3 dBi for 5 GHz

zRP SMA connectors for external antenna options

Make sure that all external antennas and their associated wiring are located entirely indoors.

The external antennas shipped are not suitable for outside use.

Note:

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

environment. Place access points accordingly.

00207

Install the Access Points

Attach the antennas to the connectors on the AP300 (see Figure 5). Rotate the knurled ring

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

Figure 5: AP300 Antenna Connection

Attach Remote Antennas

Remote antenna testing is not complete at this time.

Mount the Access Point

You can mount an AP300 in the following ways:

zHorizontally on a surface, for example set the AP300 on a shelf

zVertically on a wall

zIn the ceiling (plenum testing is not complete at this time)

Mount AP300 Horizontally

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 6.

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.

Install the Access Points

Figure 6: Horizontal AP300

Mount AP300 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 AP200s, the AP300 bracket can be attached to the

old bracket with shoulder screws (see Appendix A); you don’t have to remove the old brackets.

The AP300 ships with the mounting bracket attached. 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 one end of the Ethernet cable to the AP300 Ethernet port shown in Figure 7.

00207

Check AP300 LED Activity

Figure 7: Connect AP300 to LAN

7. Either connect an external power supply to the power connector and plug it into the wall,

or connect an appropriate PoE power device to the Ethernet port (see Figure 7).

Check AP300 LED Activity

After the AP300 is connected, the LEDs should light (see Figure 8).

Figure 8: AP300 Status LEDs

The functions of the five LEDs are described in Table 5.

When the AP300 is first connected to the controller and any time the access point is rebooted

thereafter, the AP initializes with and then is programmed by the controller. When the AP is

first powered up, all LEDs are green. Thereafter, the Status LED (see Figure 8) color reflects

the various operating states (Table 5).

Table 5: AP300 LED Descriptions

Configure AP300 Software

You can configure both the power source the AP300 will use and the channel width the AP300

will use. The default power source is 802.3af, and the default channel width is 20 MHz; these

are the lowest (and slowest) settings. Increase range and throughput by changing MIMO mode

to 3x3. The power supply option that you select determines whether or not you can use 3x3

MIMO. Be sure to change the power supply setting to either a DC power supply (provided) or a

802.11at PoE before changing MIMO mode to 3x3.

Configure AP300 Using the CLI

Use the CLI command configure ap to set the Power Supply Type and configure interface

Dot11Radio to set the Channel Width, and MIMO Mode. For example:

9. Configure Channel Width by clicking the drop-down list and selecting either 40 MHz

Extension channel above or 40 MHz Extension channel below. The ‘channel above’ and

‘channel below’ are relative to the value set in the Channel control setting (see

Figure 11, the third setting from the top). This configures the channel bonding.

10. Click OK.

Troubleshooting

zIf an AP320 continually reboots or demonstrates other unusual behavior, and MIMO Mode is

set to 3x3, there may be a mismatch of power and MIMO Mode. Make sure that you have an

appropriate power source configured, as well as attached to an AP320 with MIMO Mode set

to 3x3.

zWhen RF band selection is set to 802.11n, the security mode can only be set at clear, wpa2

or wpa2psk. This is an 802.11n restriction.

zThe ChannelWidth field value 40 Mhz-extension-channel-above is only applicable if the

extension channel above is available in the country code. For example,

A_EXT_CHANNELS=36:40 case, 40 Mhz-extension-channel-above configuration is valid for

channel number 36. Currently we support extension channels in only the US country code.

In addition, the default channel numbers for RF mode BG or A mode are changed in the US

country code (DEFAULT_B_CHANNEL=6, DEFAULT_A_CHANNEL=36).

Appendix A

AP300 Brackets

The AP300 is designed to be used with brackets supplied by other vendors. Meru APs are

compatible with the Cisco 1230 series brackets, but the 1240 and 1250 series brackets are new

and not compatible. If you reuse a Cisco 1230 series bracket, follow these steps:

1. Obtain three of the screws shown in Figure 12.

Figure 12: Shoulder Screw (specification front and side)

2. Insert the three screws into the locations indicated in Figure 13.

accordance with the manufacturer’s instructions as described in the user documen-

tation that comes with the product. For country-specific approvals, see below. Meru

Networks, Inc. is not responsible for any radio or television interference caused by

unauthorized modification of APs, or the substitution or attachment of connecting

cables and equipment other than that specified by Meru Networks, Inc. The correc-

tion of interference caused by such unauthorized modification, substitution or

attachment is the responsibility of the user. Meru Networks, Inc. and its authorized

resellers or distributors are not liable for any damage or violation of government

regulations that may arise from the user failing to comply with these guidelines.

USA — Federal Communications Commission

FCC Radiation Exposure Statement

Caution!

The radiated output power of the Meru Networks, Inc. devices is well

below the FCC radio frequency exposure limits. However, the Meru Net-

works, Inc. Meru Access Points should be used in such a manner that the

potential for human contact during normal operation is minimized. To

avoid the possibility of exceeding the FCC radio frequency exposure limits,

you should keep a distance of at least 20 cm between you (or any other

person in the vicinity) and the Access Point antennas.

Radio Frequency Interference Requirements

Interference Statement

These devices comply with Part 15 of the FCC Rules. Operation of the devices is

subject to the following two conditions: (1) The devices may not cause harmful inter-

ference, and (2) The devices must accept any interference that may cause undesired

operation.

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

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

provide reasonable protection against harmful interference in a residential installa-

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

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

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

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

this equipment does cause harmful interference to radio or television reception

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

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

measures:

Relocate this device.

Increase the separation between the device and the receiver.

Connect the device into an outlet on a circuit different from that of other

electronics.
