Step 4
Ensure the connections as still tight. If necessary, loosen the connections and ensure they
clean and dry at both ends before re-connecting and tightening to the correct torque
setting.
•
For N-type connections torque=135 N-cm (12 lb-in).
•
For F-type connections torque: 165 N-cm (15 lb-in).
Step 5
Test the connections by powering up the system and ensuring the signal values are the
same as before.
Step 6
Apply the weatherproofing materials as outlined in the RedMAX Base Station Installation
Guidelines.
Step 7
When applying tape, wrap from the bottom up, or if you are working on a horizontal
connection, wrap from the smaller diameter to the larger. Overlap each turn by 1/2. Stretch
the tape slightly for most of the wrappings, reducing the tension near the last few turns.
Apply the last wrap of tape with no tension to prevent flagging. Cut the tape end - do not
pull when cutting the tape. Compress the wrappings with both hands to insure complete
contact with all layers of tape.
Testing to Validate Repair
In order to verify that repairs and/or maintenance have been performed correctly and that
your network has been returned to optimum performance you can perform some basic
system tests.
Ideally you should establish a reference system that consists of one or two subscriber units
located at fixed locations at the farthest points within the sector or at a location that is
typically difficult to cover.
You should measure and record a set of interface readings when your system is first
installed and then use these values as a reference whenever any changes/upgrades are
made to your network.
Step 1
Power up the system. Log into the Web interface.
Step 2
From the Main menu, select Monitoring > Status.
Step 3
Record the following values or perform a screen capture of the selected screen and save
the file in a maintenance directory.
Step 4
Ensure the values are within 5% of the optimum values. The optimum values will likely be
from the time of the initial installation.
Step 5
From the Main menu, select Interface Configuration > Wireless Interface.
Step 6
Record the following values or perform a screen capture of the selected screen and save
the file accordingly.
Step 7
Again, ensure the values are within 5% of the optimum values. The optimum values will
likely be from the time of the initial installation.
