Waiting
In this state a timer starts counting down from the configured "Reswitch wait" time, which
is the minimum time between switches. When it reaches zero the device returns to the
Active state.
The Switch Config section contains these configuration parameters:
Auto switching
Checking this box enables automatic switching. When enabled the switch will switch based
on the alarm status of the inputs, following the rules set up in the Alarm status switching
config section.
When auto switching is enabled the switcher is configured to one of three return modes:
Return if main OK
When the main input becomes OK again, the controller will automatically switch back
to the main input.
Same criteria
The controller will switch between the inputs automatically when the switch criteria
are met.
Never switch back
The controller will do one automatic switch from the main input. The switch con-
troller can be rearmed by a manual switch to the main input.
When GPI is available, the current GPI signal level is presented, together with parameters to
enable switching based on GPI. Read more about switching based on GPI in
Section 5.14.3 .
GPI input state
Shows whether the GPI input state is Active or Inactive.
Enable GPI switching
Choose whether switch controller should react to GPI state changes.
GPI polarity
Option to invert the logic on which service is selected when GPI goes active. Normal
means spare is selected if GPI turns active, main is selected when it goes inactive.
The
Alarm status switching config
section at the bottom of the page is only active when you have
enabled alarm status switching. It dictates when to perform switching. On the left is a table
containing all possible alarm severities. For each severity you can choose whether you want to
perform a switch when that severity is reported on the currently active input. In addition you
can configure what the maximum alarm severity can be on the spare input.
Note: You can not enable switching on certain alarm severity levels with-
out also configuring switching on all higher severities. The web interface
automatically makes sure you follow this rule.
To the right of the table you can configure the
Switch wait period
. This value is the number of
seconds the state that warrants a switch must be in place before actual switching is performed.
