BTR 28 GHz Installation Guide
BTR 28 GHz Maintenance
Establish a regular check procedure. This quickly identifies any problem
which might develop. There are no repairable internal components in the BTR
28 GHz. Therefore, the checks focus on the exterior features of the
transceiver unit.
Mechanical Checks
Check the following mechanical areas to prevent problems:
1. Check the bolts and fasteners which hold the transceiver, waveguides, and
antenna. Vibrations due to wind can cause bolts and fasteners to loosen.
Verify that equipment is secure and properly mounted. If the bolts or
fasteners are loose, tighten them carefully. Use lock and spring washers.
2. Check to ensure that all connections between the transceiver and antenna
remain watertight. If water enters the waveguide or coaxial connections, it
can cause attenuation of the microwave signals. If water is detected, call
Nortel Broadband Wireless Access.
3. Visually inspect all equipment for signs of external damage. If signs of
damage are detected, call Nortel Broadband Wireless Access.
Note: If you detect an unsolvable problem during the electrical and
mechanical inspections, contact Nortel Broadband Wireless Access so
that action can be taken to rectify the problem.
