Installing the copper Cat5e Ethernet interface
To install the copper Cat5e Ethernet interface, use the following procedures:
Install the ODU to top LPU drop cable
on page 23
Install the main drop cable
on page 25
Install the bottom LPU to PSU drop cable
on page 27
Test resistance in the drop cable
on page 28
Attention To avoid damage to the installation, do not connect or disconnect the drop cable when
power is applied to the PSU or network terminating equipment.
Attention Do not connect the SFP or Aux drop cables to the PSU, as this may damage
equipment.
Attention Always use Cat5e cable that is gel-filled and shielded with copper plated steel.
Alternative types of Cat5e cable are not supported by Cambium Networks. Cambium Networks
supply this cable (Cambium part numbers WB3175 and WB3176), RJ45 connectors (Cambium
part number WB3177) and a crimp tool (Cambium part number WB3211). The LPU and grounding
kit contains a 0.6 meters (2 foot) length of this cable.
Install the ODU to top LPU drop cable
Fit glands to the ODU to top LPU drop cable
Fit EMC strain relief cable glands (with black caps) to both ends of the 0.6 meters (2 foot) length of pre
terminated cable. These parts are supplied in the LPU and grounding kit.
Disassemble the gland and thread each part onto the cable (the rubber bung is split). Assemble the spring
clip and the rubber bung:
Fit the parts into the body and lightly screw on the gland nut using 24 mm (0.9 in) wrench/spanner (do not
tighten it):
