Ethernet Ports
The AP340 has two RJ45 10/100/1000Base-T/TX Ethernet ports. The AP can receive power through one or both
Ethernet connections from PSE (power sourcing equipment) that is compatible with the 802.3af standard
and the forthcoming 802.3at standard, such as one of the PoE injectors available as an optional accessory
from Aerohive. (If you connect the AP to a power source through the power connector and PoE ports
simultaneously, the device 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. 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 AP320 applies the Aerohive concept of smart PoE to adjust power consumption as necessitated by
varying levels of available power to continue functioning even when the available power level drops. For
more information, see "Smart PoE" on page 111 .
The pin assignments in the PoE (Power over Ethernet) Ethernet ports follow the TIA/EIA-568-B standard (see
"Power over Ethernet Port Pin Assignments" on page 110 and Figure 3 on page 111 ).
Through the RJ45 console port, you can make a serial connection between your management system and
the Aerohive device. For more information about the Console port, see
"RJ45 Console Port Pin Assignments"
on page 113 .
Aggregate and Redundant Interfaces
By default ETH0 and ETH1 act as two individual Ethernet interfaces. For more information, see "Aggregate
and Redundant Interfaces" on page 112 . When both interfaces are connected to the network and are in
backhaul mode, the AP transmits broadcast traffic only through ETH0. The AP transmits broadcast traffic
through ETH1 only when ETH0 does not have network connectivity. When both Ethernet interfaces are
connected to the network and are in access mode, then the AP transmits broadcast traffic through all the
access interfaces: ETH0, ETH1, and all wireless subinterfaces in access mode.
Power connector 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 adaptor 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.
Console port You can access the CLI by making a serial connection to the RJ45 console port. See
"RJ45 Console Port Pin Assignments" on page 113 .
Reset button The reset button allows you to reboot the device or reset the AP to its factory default
settings. See
"Reset Button" on page 52 .
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.
