Figure 2-11 CPU Changeover by MBR Key
Note:
If the MBR (MODE switch - 4) key remains in the UP position, the CPU card stays in make-busy state.
Be sure to return the key to the DOWN position, except in special circumstances.
STEP 4 Make sure that changeover is successful by checking ACT lamp.
• Another ACT lamp should light green (SYS1 ACT lamp in this example)

STEP 5 Analyze the displayed system messages.
After the above steps are performed, the system outputs system messages [7-C] and [7-D].
Confirm that no errors occurred during the CPU changeover process.
