Establish a regular check procedure. This quickly identifies any problem 
which might develop. There are no repairable internal components in the 
BTR 2400. Therefore, the checks focus on the exterior features of the 
transceiver unit.

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.

Grounding refers to a conducting body, for example the earth, used as a 
common return for an electronic circuit and as an arbitrary zero of potential.

Grounding communication equipment limits voltage due to lightning, line 
surges or unintentional contact with higher voltage lines, by providing an 
alternative path. It minimizes damage to both the actual RF equipment and 
the indoor equipment to which it is connected.

Grounding Reunion RF equipment is critical to ensure proper system 
operation, as well as protection of personnel and equipment.

The BTR 2400 does not have a ‘ground point or stud.’ Its mounting to the 
pole serves as the ‘ground.’

Also, the cables are ‘shielded’ or armored, but do not have a ground point/
stud.
