D400 system redundancy
A redundant D400 setup allows a secondary D400 to automatically take over operations
from a paired D400 unit that has failed.
D400 equipment redundancy requires two D400 units and zero, one, or two RS232 switch
panels.
NOTE
The RS-232 switch panel is optional for Warm and Hot Standby redundancy.
A pair of LEDs marked CCU A and CCU B indicate which of the D400 units is currently active.
If the hardware or software of the active unit fails, it is automatically switched offline and
serial connections to the field are transferred to the standby unit. A toggle switch on the
RS232 switch panel can be used to switch the D400 devices between active and standby
modes.
Failover sequence
If the active D400 unit fails, the following actions occur:
1.
The standby D400 unit detects the failure through the lack of a heartbeat signal on the
ping cable or through a status change on the watchdog cable.
