Description of Arguments
(Note that all arguments are ASCII numeric codes from 48 and 57)
Query only.
Returns the redundancy state of the unit in the form x, where:
0=Offline
1=Online
EXAMPLE: <0/RED?[cr]
>0000/RED=1[cr][lf]
Command only.
This command takes no arguments.
Forces the unit to toggle the Unit Fail relay to the "fail" state for approximately
500 ms.
NOTES:
1) If the unit is a 1:1 pair and it is currently the 'Online' unit, this forces a
switchover so the unit will then be in 'Standby' mode
2) 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.
EXAMPLE: <0/FSW=[cr]
