Step 7: Plug in the Cables
1. Plug one end of the Cat5/Cat5e or better Ethernet cable (5.5 mm/.217 in OD maximum) into the Ethernet (RJ45) jack
of the device. Ensure that the cable connector is latched securely. You can hear a click sound when the cable
connector latches into the jack, then tighten the sealing nut by hand.
: Always use a straight cable from PoE to the device. When you use a 4-pair cross over ethernet cable, the reload
functionality gets activated and forcibly deletes the operating image.
2. Connect the other end of the Cat5/Cat5e or better cable to the LAN+DC port on the PoE Injector.
3. To connect the device directly to a Personal Computer, connect an Ethernet cable between the network interface card
in the Personal Computer and the RJ45 LAN port on the PoE Injector.
4. To connect the device through a hub or a switch to a Personal Computer, connect an Ethernet cable between the
network interface card in the Personal Computer and the hub. Connect another Ethernet cable between the hub and
the RJ45 LAN port on the PoE Injector.
Step 8: Install Surge Protector
Proxim recommends two approved lightning surge protectors to be installed, one near to the device and the other at the
building ingress point.
: To buy a suitable Surge Protector, place an order separately with your distributor.
Perform the following steps to ensure proper surge protection:
1. Mount the provided surge protector near the outdoor device and use 10 AWG or a better gauge wire to connect the
protector's ground lug to the appropriate mounting ground point. The outdoor device and co-located surge protector
should have a common grounding point by using the shortest possible grounding cable.
2. Mount a second surge protector near the building ingress and use 10 AWG or a better gauge wire to connect the
surge protector's ground lug to earth ground as shown in the figure below.
