Connecting the Device to a Source of Power
The Power Service Unit can be used to provide PoE power and battery backup for the Gateway. Please refer
to the Power Service Unit Installation Guide for more information (Trilliant document PL-0042A, Installation
Guide, SecureMesh 24V PSU). Alternatively, the site may have its own Uninterruptible Power System that can
be used along with a PoE injector to provide 24V power and data over an Ethernet cable; terminating in an
8P8C connector as per TIA/EIA-568-B.
Connect the Power over Ethernet (PoE) injector to the Surge Protector
Both power and data are provided over the Ethernet cable connection to the Gateway.
Always use CAT5e (outdoor CAT5) cable that is shielded (Shielded Twisted Pair – STP), UV protected, with a
drain-wire. The Gateway has an auto-sensing Ethernet port and therefore, either a straight through or a cross-
connect cable may be used.
The cable seal gasket (glands) is water-tight and will not allow terminated cables to be passed through. The
cable will have to be re-terminated. Therefore, it may be best to perform the termination on the ground before
beginning the installation.
A sufficient portion of the cable shielding must be available to be connected to the ground bolt.
•
Run an un-terminated CAT5e cable through the open glands on the surge protector.
•
Strip the protective coating from the outside of the CAT5e cable to a sufficient length that the shield of the
cable may be connected to the ground lug of the surge protector and the twisted pairs may be connected
to the RJ45 or the connector block. Connect the cable shield (drain wire) to the internal ground lug.
•
Either terminate the cable from the PoE using an RJ45 connector or terminate all eight cables to the
terminator block. The screw down terminator block is removable from the base board of the surge
protector to ease connections. Please note that the pin-outs of the RJ45 are standard
TIA/EIA-568-B.
The
screw down terminal block wiring diagram is listed on the main board.
