3. Fully administer IPSI duplication (ipserver-interface duplication). Verify
by using list ipserver-interface.
4. Activate PNC-DUP through the change system-parameters duplication
form. This is not allowed if any component of either PNC (A or B) is busied
out.
5. The system must insert all connectivity-related components for both
standby and active PNC, a process that takes up to 5 minutes, depending
upon circuit pack insertion. The process finishes when the first terminal
login prompt appears.
6. The PNC-DUP initialization anti-thrashing timer must expire (this occurs 5
minutes after completion of board insertion, PNC interchange, or system
reset of level 2 or higher).
To Disable PNC Duplication
To disable PNC duplication perform the following sequence of steps:
1. Verify that the A-PNC is active. A forced interchange may be required.
See reset pnc.
2. Busyout the standby PNC (B-PNC).
3. Turn off the system parameter for PNC-DUP through change
system-parameters duplication.
4. Remove the B-PNC connectivity by removing the Board Locations on the
change fiber form for ATM PNC.
5. Remove the B-PNC circuit packs (ATM-EI boards). Use change circuit
pack UUC.
6. Disable administration of PNC duplication on the change
system-parameters customer-options form by changing the PNC
Duplication field to n.
Notes:
■ Alterations to PNC that involve only the addition of connectivity can
be done with PNC-DUP operational.
■ Alterations requiring the removal of connectivity must be done with
PNC-DUP removed.
■ PNC-DUP must be removed and translations should be saved
before making any hardware changes.
