4.12.1.
Requirements
•
A valid license (MIS 1-11) must be installed for the
backup device
(see 3.8 Licenses for Software Extensions on page 51).
•
All devices must be connected via the control ports (ideally in the same IP subnet)
•
The backup device should be identical in construction to the monitored devices so that all outputs are redundant. If a device
with fewer outputs is used as a backup device, only the available output channels are replaced in the event of a fault.
4.12.2.
Configuring Device Redundancy
Device redundancy is configured on the backup device.
Click MAINTENANCE > DEVICE REDUNDANCY.
The DEVICE REPLACEMENT dialog opens.
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.
Under CONDITIONS TO REPLACE THE DEVICE, select the conditions under which to switch to the backup device:
•
Input failure:
The input data rate at IPTV IN1 and IPTV IN2 is below the configured minimum input data rate.
•
Output failure:
The output data rate (sum of the data rates of all active modulators) is below the configured minimum
output data rate.
•
RF level to low
: The measured output level is too low compared to the user-configured output level (initialization
→
Phase3
→
Common output level)
