Using Full Tracking Backup
To use Full Tracking Backup, follow these steps:
1. Turn system on. As part of the startup process, the show in console
A’s memory is copied to console B, overwriting the contents of B.
2. If the show you want to run is not in A’s memory, insert the show
diskette into the main console’s diskette drive after the Stage display
appears. Only the main console’s diskette drive may be used when
FTB is activated.
3. Read show into the main console’s memory from diskette. The show
is read simultaneously into the backup console. Continue using
consoles normally.
If the main processor does not contact the backup processor within 30
seconds, the following message appears: System B does not respond.
System A is now operating as a stand-alone system. System B has
been disconnected from the network. To reconnect System B to the
network, you must reboot both System A and System B.
Press [Clear] to remove the message. You can now use the main console
in normal, single console operation.
If either console fails, the other console takes control automatically and
allows you to use the functioning console in normal, single console
operation.
If the link between the two consoles is interrupted, the system informs
you and allows you to use both consoles in normal, single console
operation.
Full Tracking Backup with an LPC
A Full Tracking Backup system may consist of two tracking consoles, or
of one console and a Lighting Playback Controller (LPC). In a system that
includes an LPC, the A/B keyswitch on the console remains active
regardless of which processor is in control. You can always use the
keyswitch to switch from one to the other.
For more information regarding running a show from an LPC, please refer
to the LPC QuickGuide that came with your LPC.
