STEP PROCEDURE
1. CT Output Power
Note: This test is only required on initial installation. If adding a shelf and rack is in service
omit this test.
In order to commission the Output power of the rack, a Power Meter must be connected to
the N-Type connector on DIP/LNA 1 at the top of the rack.
1. Switch rack off by placing both breakers in the off position.
2. Connect Power Meter to the N-Type connector on DIP/LNA1 at the top of the rack
ready to measure the power output. The output from shelves 1 and 2 is on DIP/LNA1.
The output from shelves 3 and 4 (the modem shelves are located in the expansion rack
) is on the DIP/LNA2 or TX filter. The port not under test should be terminated with a
15W termination.
