20 Check the diagnostics Input Register (Input Register 30689) to verify that
the "primary" FCU is active. This is indicated by status bit 12=0. (If the
"backup" FCU is active status bit 12=1).
21 Power down the active FCU.
Comment: The "backup" FCU switches from inactive to
active.
22 Make sure that the backup FCU is active. This is indicated by status bit
12=1 (see step 20).
23 Power down both FCUs, and then power up the FCUs again starting with
the "primary" FCU as described in step 18.
24 Select the FCU Slave Database tab from the Properties menu, and con-
figure the FCU pair like you would configure a single non redundant
FCU. Both FCUs will receive the same data. Switch between the FCUs
to make sure that the same data was stored in both FCUs.
