AP340 Hardware User Guide

To mount the AP340 to a standard 1"-wide track in a dropped ceiling, you need the mounting plate, two track clips, and two Keps nuts that ship with the AP340. You also need a drill, a wrench, and—most likely—a ladder.

1. Nudge the ceiling tiles slightly away from the track to clear some space. Use the steps in the illustration to attach the track clips and the mounting plate to the ceiling track.
2. Press the track clips against the ceiling track and swivel them until they snap into place, gripping the edges of the track.
3. If necessary, slide one or both of the clips along the track to position them at the proper distance (2 1/4" or 7 cm) to fit through the holes in the mounting plate.
4. Insert the mounting plate over the screws attached to the track clips, and use the Keps nuts to fasten the plate firmly to the screws on the clips.
5. Use a wrench to tighten the nuts firmly to the bolts and secure the plate to the track.
6. Through the oblong opening in the plate, drill a hole in the ceiling tile. Then pass one or both Ethernet cables through the hole, and if you plan to supply power from an AC power source rather than through PoE, pass the power cable through as well.

• You can tie the cables to the tie points (small arched strips) on the mounting plate to prevent them from being pulled out of their connections accidentally.

7. With the AP upside down, align the port side with the bottom end of the mounting plate. Push the AP upward and insert the four tabs on the plate into the four slots on the AP.
8. Slide the AP toward the bottom end of the plate to lock the tabs inside the slots.
9. Attach the antennas and connect the cables. When you are done, replace the ceiling tiles.

To mount the AP340 in the plenum space above a dropped ceiling grid, you need the mounting plate, hanger clip, and a standard 24"-wide hanger frame, which can be ordered separately (SKU# AH-ACC-BKT-PLENUM).

1. Insert the hanger clip through the large hole in the mounting plate. Squeeze the hanger clip to pull the tabs o the feet inward until they snap upward into the two holes on either side of the larger hole.

2. Align the v-shaped tabs on the mounting bracket with the tab slots on the bottom of the AP. Insert the v-shaped tabs into the tab slots until they click into place.
3. Attach external antennas if they are required.

4. To install the hanger frame in the ceiling plenum, insert the hanger clip up through the center slot in the hanger frame. Rotate the AP and the attached mounting plate counterclockwise until the clip locks in place against the sides of the crossbar.

5. Connect one or two Ethernet cables to the network, and—if not using PoE—connect the power cord to a power source. When you are done, replace the ceiling tiles.

You can suspend the AP340 from a horizontal beam, post, strut, or girder. In addition to the mounting plate, you need a quad-toggle, a 1.5 mm (0.059 inch) wire rope with hook, and a locking device. ERICO® supplies these items in its CADDY® SPEED LINK product line. The part number for the quad-toggle is SLD15QT250 and that for the set that includes the wire rope, hook, and locking device is SLD15L2S. These items are available through various suppliers. Use the following steps and the illustration to install the suspended mount assembly.

1. Secure the four toggle strands to the mounting plate by inserting the metal cleat at the end of a strand through a hole in the plate. The recommended holes are shown in red in the illustration below.
2. Slide the oblong washer along the strand and pass it through the hole.
3. Pull the strand upward to lock the cleat and washer against the underside of the plate.
4. Align the v-shaped tabs on the mounting plate with the tab slots on the bottom of the device and push on the tabs until they click into place.

5. Wrap the wire rope around a beam, clip the hook to the rope, and then pull the rope down until it is taut against the beam.
6. Push the wire rope down through the vertical side hole in the locking deice and through the loop in the quad-toggle.
7. Push the wire rope up through the center hole in the locking device. Continue pulling the rope to raise the AP to the desired height. To lower the AP, see "Height Correction".

3. Attach antennas to the antenna connectors on the AP, connect one or two Ethernet cables to the network, and—if not using PoE—connect the power cord to a power source.

If you accidentally pull too much wire rope through the locking device, raising the AP too high, and you then need to lower it, do the following: Take a tool, such as a screw driver with a 1/8” flat tip, and press it against the lip of the inner tube in the opposite direction from the arrow on the outside of the locking device. This releases its grip on the rope, allowing you to pull the rope out the same way it was inserted. While maintaining pressure on the tube, adjust the rope until the AP is at the height you want. When you are satisfied, stop pressing against the tube so that it can regain its grip on the rope.

You can use the mounting plate to attach the AP340 to any surface that supports its weight (3 lb. or 1.36 kg), and to which you can screw or nail the plate.

Attach the mounting plate to the surface, and the AP to the mounting plate as shown in the illustration.

• You can tie the cables to the tie points on the mounting plate to prevent them from being pulled out of their connections accidentally.

To lock the AP to the mounting plate, use either a Kensington® lock or the lock adapter that is included with the mounting kit, and a small padlock (not included).

To use a Kensington lock, loop the cable attached to the lock around a secure object, insert the T-bar component of the lock into the device lock slot on the AP, and then turn the key to engage the lock mechanism.

To use the lock adapter, follow these steps:

1. Insert the T-shaped extension on the adapter into the device lock slot, and rotate it clockwise so that the curved section extends through the slot in the mounting plate.

2. Link a padlock through the opening in the adapter and engage the lock to secure the AP to the mounting plate. The opening is 1/8” (0.3 cm) in diameter at its narrowest.

You can see the hardware components for the AP340 in the following illustration, and read about them in the descriptions below.

• The rear surface of the AP340 is used for heat dissipation to reduce the internal temperature. Consequently, it can become hot, so use caution when handling it.

The five status LEDs on the top of the AP indicate various states of activity through their color (dark, green, amber, and red) and illumination patterns (steady glow or pulsing). The meanings of the various color and illumination patterns for each LED are explained below:

Power

• Dark: No power
• Green (steady): Powered on and the firmware is running normally
• Green (flashing): Firmware is booting up
• Amber (steady): Firmware is being updated
• Amber (flashing): Alarm indicating a firmware issue has occurred
• Red (steady): Alarm indicating a hardware issue has occurred

ETH0 and ETH1

• Dark: Ethernet link is down or disabled
• Green (steady): 1000 Mbps Ethernet link is up but inactive
• Green (flashing): 1000 Mbps Ethernet link is up and active
• Amber (steady): 10/100 Mbps Ethernet link is up but inactive
• Amber (flashing): 10/100 Mbps Ethernet link is up and active

WIFI0 and WIFI1

• Dark: Wireless interface is disabled
• Green (steady): Wireless interface is in access mode but inactive
• Green (flashing): Wireless interface is in access mode and active
• Amber (steady): Wireless interface is in backhaul mode but inactive
• Amber (flashing): Wireless interface is in backhaul mode and is connected with other hive members
• Green and amber (alternating): Wireless interface is in backhaul mode and is searching for other hive members

You can adjust the brightness level from bright (the default) to soft to dim, or turn it off completely in ExtremeCloud IQ. Navigate to Configure > Network Policy > Additional Settings > Network Service > Management Options. Turn Management Options on and scroll down to the System Settings section. Use the LED brightness drop-down to select the brightness level that you want.

• When you change the brightness setting here, the new setting will apply to all devices under this network policy. To change the LED brightness for a single device, establish a console connection and use the CLI command.

To turn the LED on or off and select the level of brightness using the CLI, enter:

system led brightness [ bright | soft | dim | off ]

For devices running HM Classic, you can set the LEDs for all APs on your network to blink or remain steady. Navigate toHome > Device Management Settings > LED Mode.

The AP340 has two RJ45 10/100/1000Base-T/TX Ethernet ports (Eth0 and Eth1)and one RJ45 Console port. The Eth0 port supports smart PoE (power over Ethernet) from PSE (power sourcing equipment) that is compatible with the 802.3af and 802.3at standards. Extreme Networks provides suitable PoE injectors as an optional accessory.

• When the AP is using 802.3af PoE on ETH0, ETH 1 is automatically turned off, which prevents you from aggregating ETH0 and ETH1.

If you connect the AP340 to a power source using the power connector and the PoE port at the same time, the AP draws power through the power connector and automatically disables PoE.

You can configure ETH0 and ETH1 as two individual Ethernet interfaces, combine them into an aggregate interface to increase throughput, or combine them into a redundant interface to increase reliability. For more information, see "Aggregate and Redundant Interfaces".

You can connect the AP340 to a wired network or to a wired device (such as a security camera) through these ports using bridging. They are compatible with 10/100/1000Base-T/TX and automatically negotiate half- and full-duplex connections with the connecting device. They are autosensing and adjust to straight-through and crossover Ethernet cables automatically.

The pin assignments in the PoE Ethernet ports follow the TIA/EIA-568-B standard (see "Extreme Device Pin Assignments").

The AP340 applies the Extreme Networks concept of smart PoE (power over Ethernet) to adjust power consumption as necessitated by varying levels of available power to continue functioning even when the available power level drops.

Through the RJ45 console port, you can make a serial connection between your management system and the Extreme Networks device. The management station from which you make a serial connection to the AP340 must have a VT100 emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems). The serial connection settings are: 9600 bits per second, 8 data bits, no parity, 1 stop bit, and no flow control.

To reset the device, or restore the factory configuration, insert a paper clip or similar tool into the pinhole and press the Reset button. To reboot the device, hold the button down between 1 and 5 seconds. To return the configuration to the factory default settings, hold it down for at least 5 seconds. After releasing the button, the Power LED goes dark as the system reboots. Then it pulses green while the firmware loads and the system performs a self-test. After the software finishes loading, the Power LED glows steady green.

To prevent the Reset button from resetting the configuration, enter this command: no reset-button reset-config-enable. Pressing the button between 1 and 5 seconds will still reboot theAP340, but pressing it for more than 5 seconds will not reset the configuration.

The 48-volt DC power connector (0.625 amps) is one of two methods through which you can power the AP340. To connect it to a 100 – 240-volt AC power source, use the AC/DC power adapter that is available as an extra option. Because the AP does not have an on/off switch, connecting it to a power source automatically powers on the device.

The AP340 can accept up to six detachable dipole antennas. The three shorter antennas are designed for the 5 GHz band and have a 2-dBi gain. The three longer antennas are designed for the 2.4 GHz band and have a 4.9-dBi gain. These antennas are omnidirectional, providing fairly equal coverage in all directions in a toroidal (donut-shaped) pattern around each antenna. For greater coverage on a horizontal plane, it is best to orient the antennas vertically. So that you can easily do that whether the AP chassis is mounted horizontally or vertically, the antennas hinge and swivel. These antennas support MIMO technology (see "MIMO and MU-MIMO".)

Connect the longer antennas, which support 2.4 GHz frequencies (for IEEE 802.11b/g/n), to the connectors on the side panel with the Ethernet ports. Connect the shorter antennas, which support 5 GHz frequencies (for IEEE 802.11a/n), to the connectors on the side panel with the device lock slot.

For detailed information about how to configure external antennas on AP340 devices and other Extreme Networks devices that support them, see "Antennas".

This illustration shows the relationship between the antennas and the internal radios on the AP340.

The wifi0 interface links to radio 1 (frequency range = 2.4 GHz for IEEE 802.11b/g), and the wifi1 interface links to radio 2 (frequency range = 5 GHz for IEEE 802.11a). These interface-to-radio relationships are permanent. When deciding how many antennas to use, consider the types of wireless clients—802.11n only, 802.11g/n, 802.11b/g/n, or 802.11a/n—the area needing coverage, and the RF environment.

You can physically secure the AP by attaching a lock and cable (such as a Kensington® notebook lock) to the device lock slot or by using the lock adapter that is included in the mounting kit and a padlock. See "Lock the AP340".
