Replacing a faulty power supply
Replacing one of the power supplies can be achieved without disruption to traffic.
If a power supply has failed, the associated radio will have failed which will have caused the protection
switch to switch-over to the other radio. It will not have switched back unless the power was restored and
another problem occurred which caused a switch-over.
1. If the A power supply is faulty, ensure that the B radio is active (whether it be the primary or
secondary radio).
If the B power supply is faulty, ensure that the A radio is active (whether it be the primary or
