If your system is properly configured, the primary and
secondary LEDs will not be solid red. Your backup system is
ready.
Verify the Backup System
To verify your system:
1. Place the odd node keyswitch in Run mode.
The Primary LED on the 1785-CHBM cartridge should turn
solid green.
2. Place the even node keyswitch in Run mode.
The QUAL LED on both 1785-CHBM cartridges should turn
solid green. The Secondary LED on the even node should be
solid yellow.
Your ControlNet Hot Backup system is now up and running.
