Install the AP550

The following sections describe how to install your Extreme NetworksAP550 devices, connect them to the network, and start managing them in ExtremeCloud IQ.

Shipping Carton Contents

The AP550 access point shipping carton contains the following items:

Mount the AP550

You can mount the AP550 on a flat surface, a wall, or to the tracks of a dropped ceiling grid. The following sections describe these installation methods.

Wall or Non-dropped Ceiling Mount

Attach the AP550 to any vertical or horizontal surface that will supports its weight (2.2 lb (1 kg)), and to which you can install wall mount screws. Use the following procedure.

  1. Use the bracket keyholes as a template to mark the mounting hole locations, and drill two corresponding holes in the wall or drywall ceiling.

  1. Install two wall mount screws (and plastic anchors if necessary). Leave the screw heads far enough away from the wall so that the bracket will slip over them (you can test this using the bracket). If you are connecting the device to cables from inside the wall, drill an access hole in the wall for the cables, if necessary.
  1. Attach the device to the bracket by lining up the mount tabs on the bottom of the device with the corresponding mount tab depressions on the bracket (see illustration above). Slip the device tabs under the edges of the bracket tab depressions and rotate the device until it clicks into place on the bracket.
  2. Mount the device on the wall or ceiling by slipping the bracket keyholes over the screw heads and sliding the screws into the narrow part of the keyhole.

To remove the device from the bracket, use a small flat-blade screwdriver or similar tool to depress the mount clips on the bottom of the device and release it from the bracket, as shown in the illustration.

Dropped Ceiling Track Mount

You can mount the AP550 in either a square or diagonal position on a standard 15/16"-wide track (2.38 cm) in a dropped ceiling. A diagonal mount requires the diagonal mount bracket that ships with the device. This section describes how to do both installations.

Square Dropped Ceiling Track Mount

Slip the mount tabs over the edges of the ceiling track as shown in the illustration, then rotate the device slightly until the mount clips click into place over the track edges.

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 (AH- ACC-BKT-80211AC-KIT).

Diagonal Dropped Ceiling Track Mount

Follow these steps and the illustration to mount an AP550 in the diagonal position on a standard dropped ceiling track.

  1. Attach the diagonal bracket to the device by slipping the mount tabs on the device over the plain edges of the diagonal bracket.
  2. Rotate the bracket until the mount clips on the device click into place over the bracket edge.
  3. Hold the device upside down and slip the mount clips on the diagonal bracket over the edges of the ceiling track. Because you are installing the device from below, it is helpful to use your fingertips to identify the location of the mounting tabs by touch.
  4. Press the device gently against the track and rotate it until the mount clips click into place.

Secure the AP550

You can secure the AP using a Kensington ® lock in the lock slot on the side of the device, or you can order a security bracket kit (AH-ACC-SEC-KIT-80211AC) to secure it to a ceiling track or to a wall, as shown in the illustration below. For more information, contact your Extreme Networks sales representative.

Connect the AP550

Follow these steps to connect your AP550 to power and to the network.

  1. Connect a standard RJ45 Ethernet cable from ETH0 on the AP to a switch that provides PoE power, or use a PoE injector (see "Ethernet Ports".
  2. After the AP receives power, it automatically tries to get network settings and contact your ExtremeCloud IQ platform. This process takes about five minutes. When you see the AP listed on the Devices page in the Manage section of the management GUI, the initial setup is complete and you can begin managing the AP.

Hardware Components

You can see the hardware components of the AP550 in the illustration below and read about them in the sections that follow.

Hardware Component Descriptions

Status Light

The status light conveys operational states for system power, firmware updates, Ethernet and wireless interface activity, and major alarms. The AP550 has a status light on the top corner and down one side of the chassis. The colors of this light bar 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 of four seconds of light 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 turn the LED off and on using the CLI, enter:

system led [ on | off ]

Console Port

The Console port is located on the bottom of the device. Use this port to make a serial connection between your management system and the AP. 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.

Ethernet Ports

The AP550 has two RJ45 10/100/1000Base-T/TX Ethernet ports (ETH0 and ETH1) that automatically negotiate half- and full-duplex connections with the connecting device. The ports are autosensing and adjust to straight-through and crossover standard Cat3, Cat5, Cat5e, or Cat6 Ethernet cables automatically. The APs receive 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.

PSE 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 ports have 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 30 W PoE injectors as optional accessories from Extreme Networks (not available in Brazil):

Power Connector

You can provide AC power to the AP by connecting an AC power adapter to the DC power connector and a standard AC power source. Because the AP does not have an on/off switch, it automatically powers on when you connect it to a power source. AC power adapters must be ordered separately. For more information, contact your Extreme Networks sales representative.

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 disable the reset button from resetting the configuration, enter this 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.

USB Port

The AP550 has 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.

Antennas

The AP550 has thirteen antennas:

Locking 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 a security bracket (shipped separately). See "Secure the AP550".
