Each SMART microphone ships with an
Ethernet
Surge Suppressor. When installed correctly, the Surge Suppressor provides some protection
against electrical surges or discharges to equipment downstream from the
microphone.
About this task
You should install one Surge Suppressor for each microphone you install as part of
your SMART
System.
The Surge Suppressor is symmetrical. You can connect the microphone to either of the
two
RJ45
ports.
Procedure
-
Connect the Surge Suppressor's ground wire to common ground using as
short
a connection as possible.
-
Install the Surge Suppressor as close as possible to the end of the cable
opposite the microphone.
If you want to connect the microphone directly to the SMART Controller,
connect the Surge Suppressor to the SMART Controller with as short an Ethernet
cable as possible. Connect the longer Ethernet cable between the microphone and
the Surge
Suppressor.
If you are using a PoE switch in between your microphone and SMART
Controller, connect the Surge Suppressor to the PoE switch with as short an
Ethernet cable as possible. Connect the longer Ethernet cable between the
microphone and the Surge
Suppressor.
-
Use Ethernet cables that are at least
CAT
5.
-
Keep the total run of Ethernet cable, including both segments attached to the
Surge Suppressor, to 100 meters or shorter.
The Surge Suppressor is a passive component and will not extend the possible
range of a single Ethernet segment. To extend the possible range, use a
Power over Ethernet (PoE) switch, signal extender, or
Ethernet-to-fiber conversion system.
