3. Optionally, connect a RJ11 to DB9 Serial Connector to device's Serial Port for debugging and management, and
audible antenna alignment.
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, and between the hub and the RJ45 "LAN-IN" port on
the PoE Injector.
5. 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 IN" port on the PoE Injector.
Step 9: Connect the Antenna
:Applicable only to MP-8160-BSU and MP-8160-SUA.
Connect the antenna to the device antenna port by connecting the straight N-male end of the cable to the device antenna
port and the right angle N-male end of the cable at the antenna.
: Record which port each antenna polarization is associated with to ensure that each side matches and aid in
configuration.
Step 10: 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.
: For an additional 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.
