The DEVICE REPLACEMENT dialog opens.
Under SELECT DEVICE TO MONITOR a table lists the devices that are located in the same subnet (in the
example 192.168.0.xxx)
Select the device to be monitored.
If the device is on a different subnet, enter its IP address manually and click READ NAME.
CONDITIONS TO REPLACE THE DEVICE contains the conditions for switching to the backup device.
∂
Input fail:
The minimum valid data rate is defined at MAINTENANCE
→
Input port redundancy. It is also
evaluated as failure if the input data rate is below the configured minimum data rate after a possible IPTV
input port change.
∂
Output fail:
The unit does not produce a valid output stream even when valid input data is received.
∂
RF level to low
: The measured output level is too low compared to the user-configured output level
(initialization
→
Phase3
→
Common output level)
∂
Power fail
: The internal voltage is too low (<11.0 V).
∂
Temp to high:
The temperature of the processor rises too high ( >90°C). At this temperature, the unit will
still operate normally, but probably there are ventilation problems and the temperature will continue to
rise. Selecting this condition allows an immediate smooth transition before the temperature rises so high
that the processor may stop working.
∂
No connection
(>120s): The backup device is not able to connect to the monitored device via the Control
port within 120 s.
Note: This option requires special caution!
For example, a loose Ethernet cable can
separate the two devices, which can lead to an unwanted replacement, and both devices send HF output
signals simultaneously.
Switching to the backup device is normally done after the device has been in an error state for more than 60
seconds (exception for the No connection error (>120s)).
Switching is only done if the backup device does not also fail. Switching will not occur, for example, if the IPTV
input is missing on both devices or both are connected to the same failed power source.
