CPU controls

Initialize button

Normal/maintenance switch

Switches and buttons on common equipment cards allow you to control CPU
activity and clear common equipment faults.
Pressing the manual initialize (Man Int) button associated with the active
CPU starts the Initialize Program. The Initialize Program clears common
equipment faults and then rebuilds call-dependent data and generates system
messages indicating the status of the system. This process is called an
initialization. Call processing is briefly interrupted during an initialization.
Manual initialize buttons are located on the following cards:
• In Options 51C, 61C, 81, and 81C, the initialize button is on the
NT6D66, NT9D19, NT5D10, or NT5D03 Call Processor Card.
There is a normal/maintenance (Norm/Maint) switch on the Call Processor
Card. Figure 7 shows the location of the switch on the Call Processor Card.
In dual CPU systems (Options 61C, 81, and 81C), you use this switch as
follows to keep the dual CPUs from switching, or trying to switch, when you
are testing or replacing common equipment hardware on the inactive CPU:
• On the CPU you are not testing or replacing, set the switch to Maint. This
CPU will be active.
• On the CPU you are testing or replacing, set the switch to Norm. This
CPU will remain inactive as long as the other CPU is set to Maint.
For regular operation in dual CPU systems, set both normal/maintenance
switches to Norm. For an Option 51C (a single CPU system), set the switch
to Maint.
