12 Meru Access Point Installation Guide © 2010 Meru Networks, Inc. Best Practices for an AP300/AP1000 Network AP1000 Beta TestBest 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 possible, do not deploy AP1000 and AP300/AP320i at the same physical location; we recommend 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. Assumptions for the above best practices include:AP1000 is using Virtual Port with BSSID Virtual Cell. AP320i is using Virtual Port 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.)

14 Meru Access Point Installation Guide © 2010 Meru Networks, Inc. Determine Power Requirements AP1000 Beta TestDetermine Power RequirementsPower requirements vary, depending on which AP300 radios are deployed and what MIMO mode is used. See the chart below for supported power sources for different radio configurations. 802.af PoE UsageWhen 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 radio802.3at PoE UsageWhen using System Director 3.6/4.0/4.1 and 802.3at, the following radio combinations are recom-mended:Single 3x3 radioDual 2 x 2 radios Dual radio with one set to 2x2 and the other one set to 3x3 Radio 1 MIMO Radio 2 MIMO 802.3af PoE 802.3at PoE DC Power2x2 2x2 2x2 3x3 3x3 2x2 3x3 3x3 Do not recommendlimitation below
Installation Requirements © 2010 Meru Networks, Inc. Installing AP300 15AP1000 Beta Test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/AP300i 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 providedFor a list of supported PoEs, see the appendix Supported Power Over Ethernet Devices for Meru APsInstallation RequirementsAn array of holes on the mounting bracket allows the AP300 to be mounted on the wall and over junc-tion 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. A template of this bracket is included in Appendix E of this guide.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.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 not provided)Above hanging ceiling tiles. Suitable for use in environmental air space in accordance with the Section 300-22(c) of the National Electric Code and Sections 2- 128.12 - 010 (3) and 12 - 100 of the Canadian Electrical Code.

Install the AP300 © 2010 Meru Networks, Inc. Installing AP300 17AP1000 Beta TestRelatively 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. 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. Access to wall outlet or a to a Power over Ethernet (PoE) 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-only 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 place-ment with this pattern in mind. Figure 7: Coverage Pattern for AP300 When Ceiling MountedMost 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 install APs near metal objects, such as heating ducts, metal doors, or electric service panels.For best coverage, orient antennas as shown in Figure 6.Attach the Provided AntennasAll 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.) Meru supplied antennas are suitable 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. ceilingfloor

20 Meru Access Point Installation Guide © 2010 Meru Networks, Inc. Install the AP300 AP1000 Beta TestInstall the Remote Antenna Mount (optional)Use the optional Meru Remote Antenna Mount (ACC-ANT-MIMO-MNT) 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.Figure 8: Remote Antenna MountThe remote antenna mount kit includes:Antenna 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. Triangular ceiling mount clip for attaching to hanging ceiling (includes bolt assembly) Three self-adhesive pads for the bottom of the unit (over the screws)Two wall mount screws with anchorsCeiling Mount TemplateInstallation diagramInstall the Remote Antenna Mount on the CeilingTo connect the Remote Antenna Mount to the ceiling, refer to the installation diagram from the ship-ping box while following these steps:1.

Install the AP300 © 2010 Meru Networks, Inc. Installing AP300 27AP1000 Beta TestInstall the Access PointAP300 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 Above a Suspended Ceiling (Plenum)Mount AP300 in a Hoffman EnclosureMount AP300 Horizontally on a ShelfWhen mounting an AP300 horizontally, remove the mounting bracket. Be sure to position the antennas vertically when an AP300 sits on a surface. Mount AP300 Vertically on a WallNote: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. 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. 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 screws3. 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 switch and the other end to the AP300 Ethernet port.

For each antenna, loosen the knurled ring at the base of the antenna, point the antenna down, then retighten the ring.12. Connect one end of the PoE Ethernet cable to the Ethernet connector.13. Check that the AP300 is operating correctly before replacing the ceiling tile to the ceiling. Verify correct operating using the LEDs, as shown in Check AP300 LED Activity.Mount AP300 in a Hoffman EnclosureMeru has designed a custom mounting bracket compatible with a Hoffman enclosure (www.hoffmanon-line.com). This bracket is available exclusively through Meru and orderable as part number ACC-AP300-BHE. To mount an AP300 in a Hoffman enclosure, follow these steps:1. Place AP300 upside down on a soft flat surface.2. Remove and discard the wall/ceiling mounting bracket.3. Attach either the provided antennas or an external antenna.4. Remove and discard the four rubber feet. 5. Position the Hoffman bracket (ACC-AP300-BHE) onto the back of the AP300 with the four Hoffman mounting screws facing downwards.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.

Using a Phillips screw driver, attach the bracket using the two supplied 6-32 3/16 SEMS screws.7. Flip the assembly over and mount into the Hoffman enclosure, attach the Ethernet cable to the AP300 rotating the assembly to place the Ethernet cable within the enclosure.8. Using a Phillips screw driver, tighten the four bracket screws to the enclosure.9. Adjust the antennas as needed.Check AP300 LED ActivityWhen AP300 first connects to the controller (and any time the access point is rebooted), the AP initial-izes and is then programmed by the controller. When the AP first powers up, all LEDs are green. Figure 15: AP300 Status LEDsAfter the AP300 is connected, check the status of the LEDs. The functions of the five LEDs are described below.00230A3A2L ANS TTAPWRR F1R F200217PWRSTATLANRF1RF2

Determine what the alarm is by clicking Monitor > Dashboard > Alarms and looking at the AP alarms. You can also use the CLI commands show alarm and show log.LANoff—no power or no linkgreen—link status OK (at any speed)green/blinking—activity (at any speed)red—auto negotiation failureIf the LAN LED is red, auto negotiation failed. This means that you have a problem with cabling or with the AP’s switch.Radio 1Radio 2off—no radio presentgreen—radio enabledgreen blinking—data activityyellow—disabled or in scanning modered—failureIf one of the radio LEDs is yellow, it is either disabled or in scanning mode. To see if the AP is disabled, click Configuration > Wireless > Radio > select a radio and then look at Administrative Status, which should be set to Up. To see if the AP is in Scanning Mode, click Configuration > Wireless > Radio > select a radio and look at AP Modes, which should be set to Normal Mode. If one of the radio LEDs is red, the radio failed. Check the alarms (Monitor > Dashboard > Alarms), diagnostics (Monitor > Diagnostics > Radio), and statistics (Monitor > Dashboard > Radio) on the AP’s controller to determine the cause.
