Reset Button

The reset button located on the bottom of the device can be used to reset the access point to factory default
settings or turn off/on the LED display.
Use one of the following methods to reset the access point to factory default settings:

To reset during normal operation:

To reset during power up, hold the reset button while the access point is powering up.

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 toggle the LED display between Off and Blinking:

During the normal operation of the access point, shortly press and release the reset button using a small,
narrow object, such as a paperclip.
Power
Both ethernet ports support PoE-in (AP is a PoE-PD device), allowing the device to draw power from compliant
PoE power sources. If PoE is not available, the access point has a single 48V DC power import to support the AP-
AC-48V36C AC-to-DC power adapter kit (sold separately). When both PoE and DC power sources are available,
the DC power source takes precedence. In that case, the access point simultaneously draws a minimal current
from the PoE source(s). In the event that the DC source fails, the access point switches to the PoE source(s).
If the 555 access point is powered by both PoE ports simultaneously, it can combine power from both sources in
either shared or prioritized mode. When Eth0 is prioritized, the access point simultaneously draws a minimal
current from the Eth1 source. In the event that the prioritized port fails, the access point switches to the
