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 Aerohive (not available in Brazil):
• AH-ACC-INJ-20W-EU
• AH-ACC-INJ-20W-US
• AH-ACC-INJ-20W-AU
• AH-ACC-INJ-20W-IL
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 HiveManager NG, the status indicator glows steady white.
To prevent 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.
Antennas
The AP122 has four internal single-band antennas. 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"
