Installation Overview

The device's appearance is as in the figure below.
1. If you have purchased the wall mount
kit, proceed to place the screws on the
back of the device as shown in (Fig. 1)
2. Although internal grounding has been
done inside, in order to ensure overall
maximum performance and protect your
device it is still strongly advised to ground
the device properly; hazardous ESD can
come into contact with it and damage
your equipment. On the power terminal
block, there is a terminal for Frame
Ground, you can choose whether to
connect it to the grounding or you may opt
to connect to the grounding screw next to
the terminal block (the one chosen should
be connected at all times) (Fig. 2~3).
3. You can then choose whether to plug in
the I/O ports at this point or do it later
depending on the actual location of the
device or level of comfort for performing
such operation. Remember to plug in the
protective caps for the unused SFP and
PoE ports.
