LPU and IF cable requirements
Applies to ODU deployments only.
Use LPUs and IF cables that meet the following requirements:
•
A lightning protection unit (LPU) (from the Cambium LPU kit, part number WB3657) is
installed within 600 mm (24 in) of the point at which the IF cable enters the building or
equipment room.
•
The IF cable is bonded to the supporting structure in order to prevent lightning
creating a potential between the structure and cable, which could cause arcing,
resulting in damage to equipment.
•
The IF cable is grounded at the building entry point.
Specific requirements for the ODU
Applies to ODU deployments only.
Ensure that all ODU installations meet the following requirements:
•
The ODU and top LPU are as close together as possible.
•
The IF cable length between the ODU and top LPU is less than 800mm. The cable
supplied in the accessory kit meets this requirement.
•
The top LPU is mounted lower than the ODU.
