Connecting the Failsafe Alarm Relay

The Failsafe output relay is provided to signal critical error conditions that may occur
on the RUGGEDCOM M969F series switches. The contacts are energized upon power
up of the unit and remain energized until a critical error occurs.
One common application for this output is to signal an alarm if a power failure or
removal of control power occurs.
