to the appropriate setting: Capacitive Power Discovery/24V,
Capacitive Power Discovery/48V, or IEEE 802.3af.

On the back of the Network Jack, remove the dip switch cover.
NOTE:
If you are not using Power Over Ethernet to
power the Network Jack, skip this section. Go to
“Installing the Adapter Plate and Pass-Through Ports”
on page 15 to continue.
WARNING:
Before setting the dip switches, make sure
that power to the Network Jack is off.
Do not change dip switches 1 and 2 from their factory
default settings (OFF). Changing these settings may
result in performance degradation.
