4. Termination Of Spare RF Ports

All RF ports should be terminated if not connected.

If the Combiner Shelf is not equipped with a TX Filter, it is also recommended that the

second antenna should be terminated with a 50Ω termination. The Termination can

either be at the base of the dipole if only one feeder is fitted, or at the base of the

second feeder if the second feeder has been provided in readiness for future shelf

expansion.

5. Switch on Rack

Re-insert any modems disconnected from backplane during commissioning.

Switch the power back on at the breakers.

THIS CONCLUDES THE CENTRAL TERMINAL COMMISSIONING TESTS.
