4.5 Configuration menu
The (F) in the text represents the factory default setting.
Factory defaulting: The backup button is also used to factory default
(returning configuration settings to default values) the SBU128 on power
up, by holding it depressed for about 2 seconds until the Layer 1 LED
illuminates. At this point it must be released to perform the default. If
for any reason the button is held in for more than 10 seconds, other
LEDs will light indicating that the unit has entered other service states.
The unit must be power cycled again to exit this mode, and correctly
factory defaulted.
Any menu that is “starred” is unavailable on the terminal
screen. It is there just to provide menu similarity with other
SmartSWITCH BACKUP products.
