To mount the non-PoE switch to the wall:
Determine where you want to mount the switch. Verify that the
S 1
TEP
surface is smooth, flat, dry, and sturdy.
Attach one of the supplied brackets to one side of the switch and
S 2
TEP
use two pan head M5 screws to secure it.
Repeat the previous step to attach the other bracket to the opposite
S 3
TEP
side of the switch.
For the best support of the switch and cables, make sure that the
S 4
TEP
switch is attached securely to wall studs or to a firmly attached
plywood mounting backboard. Mount the switch with the front
panel facing down as shown here.
