56 205486 REV F Operations Manual, HPA2, Compact Outdoor SSPA
If the online amplifier enters a fault condition, the redundant switch will automatically route the
signal to the Standby amplifier. The faulted amplifier will be colored red in the Redundancy
Control Panel display. See Figure 7-16.
By clicking on the [Unit1] button (which will be labeled to correspond to the unit’s name), the
M&C Status window for Unit1 is activated, so the user may determine the cause of the fault.
See Figure 7-17. Once the fault is cleared, Unit1 can be reactivated as the online unit by
clicking on the triangular amplifier symbol for Unit2 in the System1 control panel.
If the redundant switch is manually rotated to the offline amplifier in a redundant system, an
RF switch fault will occur. The system will not attempt to switch back to its original position.
On the Redundancy Control Panel, both amplifiers will be colored red. The switch must be
manually rotated back to the online amplifier.
