The position of the Tx Waveguide Switch determines the online status of a unit
in a 1:1 Redundancy System. When the switch is oriented to allow a unit to send
RF power to the antenna (as determined by the switch's failsafe indicator), the
unit is considered to be online. Otherwise, the unit is considered to be offline.
When redundancy mode is disabled (ESW=0), the unit always reports that it is
online. This is because, in standalone mode, there are no waveguide switches
monitored and controlled by the unit. Standalone mode does not use the Tx
waveguide switch position to determine online status.
Only the offline unit is allowed to initiate a redundant switchover by throwing
the waveguide switches. The offline unit will initiate a redundant switchover if
any of the following conditions are met:
• Online unit faulted, and offline unit is not faulted.
• Inter-unit redundancy link established, and then timed out.
• Mismatched waveguide switch condition is detected.
• Unit is forced online through a remote command.
If you enable Offline Mute (OFM), then the unit will mute the RF Output when it
is offline. The OFM state also affects the LNB Bias Tee Switch position, because
the switch serves as the unit's Rx path mute, so it is therefore tied to the Mute
State (MUT) of the unit while the unit is running in redundancy mode (i.e., if
