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)
