There are two methods to reset the device to factory defaults:
Runtime reset (recommended)
The device should be running after bootup is
complete. Press and hold the Reset button for about 10 seconds until the
MGMT LED starts flashing and then becomes solidly lit. After a few seconds,
the LED will turn off, and the device will automatically reboot.
Note:
To press the Reset button, insert a straightened paper clip (or
similar object) into the hole shown above. Do not use an object that
can break and become lodged in the hole.
Power-on reset
Disconnect power from the device. Press and hold the Reset
button while connecting power to the device. Keep holding the button until the
MGMT LED starts flashing and then stops flashing after a few seconds.
The 24VDC input can connect a redundant or stand-alone DC power source (not
included) with minimum power: 56W, 25 to 16V, and 2.5 mm DC power inline
connector.
Note:
You can use the redundant DC power source as a hot spare; if the
internal AC/DC power supply no longer provides power, then the device
will switch to the DC power source without interrupting its operation.
Connect the included Power Cord to the Power port.
