Ethernet Ports
The Aruba 340 Series access point is equipped with two Ethernet ports (E0 and E1) located on the back of the device
shown in
Figure
4.
E0 port: 100/1000/2500BaseT auto-sensing MDI/MDX wired RJ45 network connectivity port
E1 port: 100/1000BaseT auto-sensing MDI/MDX wired RJ45 network connectivity port
Both ports are compliant with 802.3ab 1000BaseT Gigabit Ethernet standard, while E0 also supports both NBase-T and
802.3bz standards for 2.5bps Ethernet. Both ports support 802.3at and 802.3af to accept power from a POE source, such
as a PoE midspan injector, or a network controller.
USB Interface
The side of this access point is equipped with a USB-A port that is compatible with cellular modems. When active, this
port can supply up to 5W/1A to a connected device. See

Push Button
The push button located on the back-right corner of the device can be used to reset the access point to factory default
settings or toggle the LED display.
To reset the access point to factory default settings:
1. Press and hold the push button using a small, narrow object, such as a paperclip.
2. Power-on the access point without releasing the push button. The System Status LED will flash within 5 seconds.
3. Release the push button.
The system status LED will flash again within 15 seconds indicating that the reset is completed. The access point will
now continue to boot with the factory default settings.
To turn off/on the LED display:
During the normal operation of the access point, press and release the push button using a small, narrow object, such
as a paperclip.
Power
Aruba 340 Series access points accept Power over Ethernet (PoE-in) from IEEE 802.3at and 802.3af sources. This can be
done by linking either the E0 or E1 port to power sourcing equipment, such as a PoE midspan injector, or network
controller providing PoE via Ethernet cable.
If both Ethernet ports are used to draw power from two PoE sources simultaneously, the access point will draw from the
more capable power source (prioritizing 802.3at over 802.3af), while continuing to draw a minimal current from the
secondary source. In the event that the primary power source fails, the access point will switch to the secondary source
for a hitless failover. When both PoE sources are equally capable, the source connected to the E0 port is prioritized.
Alternatively, an AP-AC-48V36C AC-to-DC adapter (sold separately) can be used to power the access point.
If the access point is connected to both DC and PoE sources simultaneously, the device will draw power from the DC
source, while continuing to draw a minimal current from the PoE source. In the event that the DC power source fails, the
access point will switch to the PoE source for a hitless failover.
The Intelligent Power Monitoring (IPM) feature may also be used to manage the power consumption preferences for this
