Install the AP

You can mount the AP122 on a flat surface or wall, or on the rails of a standard dropped ceiling grid using the hardware on the back of the chassis.

The following sections describe how to install your AP122 devices and connect them to the network.

Shipping Carton Contents

The AP122 access point shipping carton contains the following items:

Dropped Ceiling Mount

The following steps explain how to mount the AP122 on the rail of a dropped ceiling.

Make sure that you have all the materials and tools necessary, and familiarize yourself with the safety and site hazard warnings before you install the device. You may need to drill a small hole in the adjacent ceiling tile to accommodate the cable. Before you begin, lift the ceiling tiles adjacent to the location on the rail where you will install the device for better access. Once the device is installed, you can slide it along the rail to better adjust its position.

Use the following steps to install your device to a dropped-ceiling rail.

  1. For a dropped ceiling mount, use the mount tabs and clips on the bottom of the device.
  2. Hold the device upside down and slip the mount tabs over the sides of the ceiling rail.
  3. Press the device gently against the ceiling rail and rotate it until the mount clips click into place.

Wall or Non-dropped Ceiling Mount

Use the built-in wall mount slots on the back of the chassis to attach the AP122 to any vertical or horizontal surface (such as a wall or a drywall ceiling) that supports its weight (1.16 lb, or 0.56 kg), and to which you can install wall mount screws. To mount the AP122 on a wall or other flat surface, perform the following steps:

  1. Make two marks where you want to mount the device on the wall or surface exactly 2.5" (64 cm) apart.
  2. Drill two holes that are slightly smaller in diameter than the mounting screws.
  3. Install two wall mount screws (and plastic anchors if necessary). The screw heads must protrude far enough from the wall so that the chassis will slip over the screw heads, and leave enough room to access the console connector. If you are connecting the device to cables from inside the wall, drill an access hole for the cables.
  1. Insert the heads of the screws into the large end of the wall mount slots and slide the device down (or sideways for ceiling mounts) until the screws are seated in the narrow end of the keyholes.
  2. You can lock the device to the wall or ceiling using a security bracket that can be ordered as an accessory.
  3. To remove the device from the wall or ceiling, slide the chassis up until the screw heads slip out of the wall mount slots.
  4. The AP122 is PoE powered, so you must connect an Ethernet cable directly from the ETH0 port to a PoE-enabled switch or to a PoE injector.
Note

Note

You can also mount these devices to non-standard or recessed dropped ceiling tracks using brackets designed for 9/16" (1.34 cm) tracks. These brackets can be ordered from Extreme Networks (AH- ACC-BKT-80211AC-KIT). Not available in Brazil.

Remove the Device

To remove the device, press the mount clips until they disengage from the rail, then rotate the device and pull it away from the rail. A flat-blade screwdriver will make it easier to access and press the clips.

Lock the AP

You can secure the AP using a Kensington® lock in the lock slot on the side of the device, or you can use a security bracket and a crosshead screw or a security screw. Security brackets and screws can be ordered separately from Extreme Networks (not available in Brazil).

Extreme Networks recommends a variety of Kensington locks. For more information, contact your sales representative.

Connect the AP to the Network

Follow these steps to connect your AP122 to PoE (power over Ethernet) power and to the network.

  1. Connect a standard RJ45 Ethernet cable from ETH0 on the AP to a switch.
  2. If the switch provides PoE (power over Ethernet), cabling the AP to the switch will power-on the AP in a few seconds. If the switch does not provide PoE, use a PoE injector. For more information about Extreme Networks PoE injectors, contact your Extreme Networks representative.
  3. After you power on the AP, it automatically tries to get network settings and contact ExtremeCloud IQ. This process takes about five minutes. When you see the AP listed on the All Devices page in the Manage section of the ExtremeCloud IQ GUI, the initial setup is complete and you can begin managing the AP with ExtremeCloud IQ.

Hardware Components

You can see the hardware components of the AP122 in the illustration below and read about them in the sections that follow.

Component Descriptions

Status Indicator Light

The AP122 has a status light bar on the top corner and down one side of the chassis. This light conveys operational states for system power, firmware updates, Ethernet and wireless interface activity, and major alarms. The colors of the light indicate the following states of activity:

Dark: There is no power or the status indicator is disabled.

Amber (flashing): This is an alert that indicates that the device is performing a firmware upgrade. Do not power off the device during this process.

Amber (steady): This is an alert that indicates that the CAPWAP connection has not been successfully established, or the device is booting or shutting down.

White: The device is powered on, a successful CAPWAP connection has been made, and the firmware is operating normally. During normal operation, the LED produces a slow blink consisting of 4 seconds of illumination followed by one minute of darkness. To extend the life of the status LED, turn it off completely for normal use, and turn it on when needed for troubleshooting.

To extend the life of the status LED, turn it off completely for normal use, and turn it on when needed for troubleshooting.

To turn the LED on or off or change the brightness using the CLI, enter:

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

To turn the LED off, navigate to Configure > Network Policy > Additional Settings > Network Service > Management Options. Turn Management Options on and scroll down to the System Settings section.

Note

Note

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

Console Port

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

The pin-to-signal mapping for the Console port is shown in Extreme Device Pin Assignments.

Power Connector

You can power the AP122 through the ETH0 port from PSE (power sourcing equipment) that is compatible with the 802.3af and 802.3at standards. Because there is no on/off switch, these devices automatically power on when you connect them to power.

Ethernet Port

The AP122 has one RJ45 10/100/1000Base-T/TX Ethernet port (ETH0) that automatically negotiates half- and full-duplex connections with the connecting device. The port is autosensing and adjusts to straight-through and crossover standard Cat3, Cat5, Cat5e, or Cat6 Ethernet cables automatically. The AP receives PoE power through an Ethernet connection to the ETH0 port from PSE (power sourcing equipment) that is compatible with the 802.3at and 802.3af standards.

Power sourcing equipment can be embedded in a switch or router, or it can come from purpose-built devices that inject power into the Ethernet line en route to the AP. Because the PoE port has autosensing capabilities, the wiring termination in the Ethernet cable can be either straight-through or crossover.

You can purchase your own PoE injector or purchase the following PoE injectors as optional accessories from Extreme Networks (not available in Brazil):

USB Port

The AP122has a USB port that you can use to connect USB-based beacons (iBeacon, for example) and IoT (Internet of Things) devices. To access the port, remove the screw that secures the protective cover. For extra protection, keep the cover in place when the port is not in use.

Reset Button

Use the Reset button to reset the device or restore the factory default settings. Insert a paper clip or similar tool into the Reset pinhole and press the button. To reboot the device, press the button for 5 seconds. To return the configuration to the factory default settings, press it for at least 10 seconds. After releasing the button, the indicator light goes dark, and then glows steady amber while the firmware loads and the system performs a self-test. After the software finishes loading and the AP has connected to ExtremeCloud IQ, the status indicator glows steady white.

To prevent the reset button from resetting the configuration, enter the following command:

no reset-button reset-config-enable

When this command is enabled, pressing the button for 5 seconds will still reboot the AP, but pressing it for more than 10 seconds will not reset its configuration.

Antennas

The AP122 has four internal single-band antennas: two 2.4 GHz antennas (802.11a/b/g/n)and two 5 GHz antennas (802.11a/b/g/b/ac). All antennas are omnidirectional and provide fairly equal coverage in all directions.

Lock Slot

When mounting the AP on a ceiling track or flat surface, you can secure it to the track using a Kensington® lock in the lock slot or using the security screw and bracket that ships with the device. See "Locking the AP".
