The colour of each device, together with its link (if applicable), indicates its
current status, as shown in the following table.
State Description Unit Status Link Status Connection of Active Link
Both the unit and link are green Good Good Good
Unit is green and the link is red Good Bad Not known
Unit is red and the link is green Malfunction Good Not known
Both the unit and link are red Not known Bad Bad
There is also an amber condition, which means that the item(s) is in error, but the
error does not a ect the audio.
Viewing the status of the master controllers is particularly important, especially
when you wish to swap the active master controller (see Swapping The Active
Master Controller), as it shows you which master controller is currently
controlling the network.
Swapping The Active Network
In the highly unlikely event that the active network (X or Y) develops a
malfunction, you can swap over to the standby network, making this the
active one.
NOTE: The swap function does not swap control data, as this non-audio
data nds its own way through the network. This allows the router to
swap to the inactive link, even if the active link is broken or removed.
>> To check the health of the active network
At the GUI, open the Diagnostics screen by choosing home > Diagnostics,
and then check the status of the active HyperMAC link. If it is green the link
is good, but if it is red there is a problem and you should swap to the standby
HyperMAC link.
Swapping The Active Master Controller
Although it is highly unlikely that the active master controller (MC) will develop a
malfunction, should it ever happen you will need to activate the standby MC.
>> To swap the active master controller
1. At the GUI, choose home > Files.
2. Click FILE SYNC.
3. In the Master Controller File Synchronisation window, click the
MAKE ACTIVE button of the standby MC. This will become the active one.
