6.4.3 Redundancy circuitry

If the units do not return to their initial status after a warm reboot (reset), use this procedure
to restart the units in order to reset the redundancy circuitry.

1. Turn off the Control Units by pressing the power bar switch or similar switch and wait

two seconds.

2. Turn both units back on simultaneously by pressing the power bar switch or similar

switch to ensure that both units are powered on at exactly the same time. If you cannot
ensure that the units are powered at the same time, then turn on only one unit and wait
until it has completely rebooted before turning on the other one. You will see the CU4>
prompt when the unit has finished booting up.

•

If the redundancy system is operating normally, the startup screen on each unit will
read:

Master unit:

Redundancy monitoring
system......OK

←

redundancy system is OK

Backup unit....PRESENT

←

unit detected another unit (its backup)

Status.........MASTER

←

this unit is currently operating as master

Configuration..MASTER

←

this unit was set up as the master unit

Backup status..OK

←

the other unit (its backup) is working

properly

Backup unit:

Redundancy monitoring
system......OK

←

redundancy system is OK

Backup unit....PRESENT

←

unit detected another unit (the master unit)

Status.........BACKUP

←

this unit is currently operating as backup

Configuration..BACKUP

←

this unit was set up as the backup unit

Backup status..OK

←

the other unit (the master unit) is working

properly

•

If there is an error with the redundancy system, note any messages or warnings that
appear on screen or the codes sent to the host computer, and use the corresponding
procedures in sections 6.4.5 to 6.4.7 to correct the problem.

3. If the problem persists, contact Electroline’s technical support department.
