Definition of the fault mask
Using the fault mask, you specify an individual "good status" for the connected ports and the
power supply. Deviations from this status are then displayed as errors/faults.
1. Turn on display mode A or D. Display mode A is active when the "DM" LED is not lit. Display
mode D is active when the "DM" LED flashes yellow/orange. If a different display mode is
active, you will need to press the SET/SELECT briefly (possibly several times) until the required
display mode is active.
2. Hold down the SET/SELECT button for five seconds. After three seconds, the "DM" LED begins
to flash. If you release the button before the five seconds have elapsed, the previous fault
mask will be retained.
Enable/disable the redundancy manager
1. Turn on display mode B. Display mode B is active when the "DM" LED is lit green. If a different
display mode is active, you will need to press the SET/SELECT briefly (possibly several times)
until display mode B is active.
2. Hold down the SET/SELECT button for five seconds. After three seconds, the "DM" LED begins
to flash. If you release the button before the five seconds have elapsed, the action is aborted.
3. The result of the action depends on the initial situation:
– If the redundancy manager and media redundancy were disabled, media redundancy is
also enabled after enabling the redundancy manager.
– If you disable the redundancy manager, media redundancy remains enabled.
