4. The system must insert all connectivity-related components for both
standby and active PNC. For CSS configurations this takes up to 5
minutes depending upon CSS circuit pack insertion. For Direct Connect
configurations this is declared complete at 5 minutes after the first
appearance of the terminal login prompt.
5. 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 perform the following sequence of steps:
1. Verify that the A-PNC is active. A forced interchange may be required. See
reset pnc
in Chapter 8, ‘‘Maintenance Commands’’
.
2. Busyout the standby PNC (B-PNC).
3. Turn off the system parameter for PNC-DUP via
change
system-parameters duplication
.
After PNC duplication has been removed, configuration audits will
generate the alarm shown below and possibly others. To clear this alarm,
the B-PNC fibers, circuit packs in switch node carriers ( EIs, SNIs, SNCs,
and DS1Cs), and switch node carriers must be removed as outlined in the
following steps.
01D SN_CONF 5000 255
In this case, 01D is the B-PNC switch node from which uplication was
removed.
4. Remove the B-PNC fibers by removing the Endpoint Board Locations on
the
change fiber
form for all fibers. For fibers using DS1Cs, remove the
B-PNC DS1C Board Locations on page 3 of the
change fiber
form.
5. Remove the B-PNC circuit packs starting with the switch node carrier most
distant from the SPE complex. Use
change circuit pack UUC
, page to the
B-PNC carrier and remove all of the circuit packs there. Remove all circuit
packs in the other B-PNC switch node carriers.
If the Expansion Interface circuit pack associated with the PPN is located
in the switch node carrier closest to the SPE, it cannot be removed from
translation until it has been busied-out and disconnected from the carrier
slot.
When SNI, SNC, or DS1C circuit packs are removed from a B-PNC carrier,
any alarms against them should be resolved.
6. Remove the B-PNC switch node carriers. Use change cabinet UUC and
enter not-used for B-PNC carriers.
Any alarm against the carrier such as 01D SN-CONF should be resolved.
The B-PNC carriers and associated circuit packs should not be alarmed.
