Ethernet Port

The pin assignments in the PoE (Power over Ethernet) 10/100/1000Base-T/TX Ethernet port follow the
TIA/EIA-568-B standard (see
cat5, cat5e, or cat6—and can receive power over the Ethernet cable from power sourcing equipment (PSE)
that is 802.3af-compatible. If you use cat5, cat5e, or cat6 cables, the ETH0 port can also support
802.3at-compliant PSE. Such 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
cross-over.

Description
To return the configuration to the factory default settings, hold it
down for at least 5 seconds. After releasing the button, the status
indicator goes dark as the system reboots. Then it glows blue while
the device boots and the system performs a self-test. After the
firmware finishes loading and the AP is ready to serve clients, the
status indicator glows white.
To disable 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 the AP, but pressing
it for more than 5 seconds will not reset its configuration.
The 10/100/1000-Mbps Ethernet port—ETH0—receives an RJ-45
connector. The AP can receive power through an Ethernet
connection to the ETH0 port from PSE (power sourcing equipment)
that is compatible with the 802.3af standard and the forthcoming
802.3at standard. Aerohive provides suitable PoE injectors as an
optional accessory. (If you connect the AP to a power source
through the power connector and the ETH0 PoE port simultaneously,
the device draws power through the power connector and
automatically disables PoE.)
The ETH0 port is compatible with 10/100/1000Base-T/TX and
automatically negotiates half- and full-duplex connections with the
connecting device. It is autosensing and adjusts to straight-through
and cross-over Ethernet cables automatically. For details, see
"Ethernet Port" on page
The 48-volt DC power connector (0.3 amps), with a voltage range of
36 to 57 volts DC, is one of two methods through which you can
power the AP (the other is PoE). To connect it to a 100 – 240-volt AC
power source, use the AC/DC power adaptor that is available as an
extra accessory. Because the AP does not have an on/off switch,
connecting it to a power source automatically powers on the
device.
