When Dual Device Mode is enabled, the loss of fiber link will re-initialize the PDs associated with the that
fiber port. On the 4-Port models, RJ-45 ports 1 - 2 will drop PoE power when a loss of receive link on F1
is detected and RJ-45 ports 3 - 4 will drop PoE power when a loss of receive link on F2 is detected. On
the 8-Port models, RJ-45 ports 1 - 4 will drop PoE power when a loss of receive link on F1 is detected and
RJ-45 ports 5 - 8 will drop PoE power when a loss of receive link on F2 is detected.
The PoE Reset function is also available through the web management. See Section 7.1.3.2 Port
Configuration.
3.0 APPLY AC POWER
To power the switch using the AC/DC adapter, connect the AC/DC adapter to the AC outlet. Route the power
cord through the provided strain relief for additional support. Then connect the DIN connector or barrel
connector at the end of the wire on the AC/DC adapter to the DC power connector on the switch. Confirm
that the switch has powered up properly by checking the Power LED located on the front of the switch.
Installation of the equipment should be such that the air flow in the front, back, side and top vents of the
switch are not compromised or restricted.
If the installation requires grounding, secure the grounding wire to the ground lug. See the figure below
for the location of the grounding lug.
