Force 1:1 Switch FSW= None Command only.
This command takes no arguments. Forces the unit to toggle the Unit Fail relay to
the ‘fail’ state for approx 500ms. If the unit is a 1:1 pair, and it is currently the ‘On
Line’ unit, this will force a switchover, so the unit will then be in ‘Standby’ mode.
The command is always executed by the unit, regardless of whether it is stand-
alone, in a 1:1 pair, or part of a 1:N system. FSW= (message
ok) N/A N/A
