8.8.2.1 Alarm
Linkage
Port Alarms
1>Separate
This screen allows port alarm handling to be configured. Alarms can either operate completely
independently (‘separate’) for each port, or can be linked such that the same alarm information is
always reported regardless of which serial port is used.
Alarms must be read and accepted before they can clear and return to normal. If configured as
separate, alarm reading and acceptance must be done separately for each of the two ports. This
ensures that the different hosts see all the alarms. When the alarms are linked, accepting an alarm on
one port accepts the alarm on all the other ports as well.
The status screen displays for alarm indication cannot be linked to the serial communications alarm
handling.
Linking the port alarm operations is useful in dual redundant serial link configurations between the
master station and the host computer. When Ethernet communication is being used on hot standby
systems the normal setting should be ‘Linked’.
Commands available:
-
Toggle between “Linked” and “Separate”.
