compliant power sources. This device accepts 56V DC (802.3at), or 48V DC (802.3af) nominal as a standard
powered device (PD) from power sourcing equipment, including PoE midspan injector or a PoE-sourcing network
infrastructure. The port is an RJ45 connector with pin-out details shown in

Kensington Lock Slot
The 310 Series is equipped with a Kensington lock slot for additional security.
USB Interface
The 310 Series is equipped with a USB port for connectivity with cellular modems and other USB client devices.
When powered by an 802.3at or DC source, the USB port can supply power up to 5W.
The USB interface is disabled when the access point is powered by an 802.3af PoE source.

Reset Button
The reset button can be used to reset the access point to factory default settings or turn off/on the LED display.
To reset the access point to factory default settings, follow this procedure:
1. Power off the access point.
2. Press and hold the push button using a small, narrow object, such as a paper clip.
3. Power-on the access point without releasing the push button. The System Status LED will flash within 5
seconds.
4. Release the reset 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.
Power
The Ethernet port supports PoE-in, allowing the device to draw power from an 802.3at source.
If PoE is unavailable, the 310 Series access points have a single 12V/36W DC power input to support the AP-AC-
12V30UN AC-to-DC power adapter kit (sold separately).
When both 802.3at and DC power sources are available, the DC power source takes precedence. The access
point simultaneously draws a minimal current from the PoE source. In the event that the DC source fails, the
access point switches to the 802.3at source.
The 310 Series operates without restriction when powered by 802.3at compliant and DC power sources. In this
mode, the USB interface is enabled and supports up to 1A/5W to a powered device (PD). When powered by an
802.3af PoE+ source, the access point operates in power-saving mode. In this mode, the USB interface is
disabled. See
