CADAC consoles are designed to work continuously with two power supply systems
- ‘main’ and ‘backup’. The ‘main’ power supply pair (1 off ‘18v’ unit and 1 off 13V/48V
unit) are designated ‘System 1’. The ‘backup’ power supply pair (1 off ‘18V’ unit and
1 off 13V/48V unit) are designated ‘System 2’
On each power supply, turn all AC input switches to the ON-position.
Start the ±18V and 13V/48V PSUs (in one PSU system) simultaneously, by pressing
and holding the START-buttons until you hear the relay click. The CCM will cycle
through its self-test routines and any Master Mute switches previously selected will
be set ON, thus protecting external equipment from possible DC pulses when the
±18V PSUs are started.
Repeat for PSU system 2. If you cannot start the PSUs simultaneously, start the 13V/
48V first. However, do NOT operate the console for long periods without all power
lines on.

Always use the following procedure:
■ ■ ■ ■ Power up console
■ ■ ■ ■ Power up Séance box
■ ■ ■ ■ Select PC1 on the CCM and power up the first computer. Wait until the PC1
computer has completed its boot-up routine, then...
■ ■ ■ ■ Switch to PC2 on the CCM and power-up the second computer and wait until it
has completed its boot-up routine.
Once both computers have booted correctly, they should allow the keyboard and
monitor to be switched back and forth without problems.
If the overall cable length for the keyboard and monitor are very long (greater than
5m), it may be necessary to use a keyboard and a monitor booster unit to retain key-
board reliability and a clean monitor display.
