Maintenance-Object Repair Procedures
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 media server 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 PN is located in
the switch node carrier closest to the media server, 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.
7. Disable PNC duplication on the change system-parameters
customer-options form by changing "PNC Duplication" to no.
If an alarm exists against any Expansion Interface circuit pack connected
to a B-PNC carrier, attempt to use test board UUCSS long clear to clear
the alarm.
Alterations to PNC which involve only the addition of fiber connectivity can be
done with PNC-DUP operational. Alterations requiring the removal of fiber
connectivity must be done with PNC-DUP removed. PNC-DUP must be removed
and translations should be saved before any hardware changes are made.
Steady State LEDs
The LEDs of PNC components in a stable duplicated system should appear as
follows:
The active IPSIs are functioning as archangels in IPSI port networks.
The active EIs in the PNs are functioning as archangels. Their LEDs flash
in a pattern of 2 seconds on 200 milliseconds off (PN without an IPSI).
The PN standby EIs amber LEDs are off (PN without an IPSI).
The PN active EI amber LED is on solid (PN with an IPSI).
The PN standby EI amber LED is off (PN with an IPSI).
The SNIs on the active switch node(s) have amber LEDs on solid.
The SNIs on the standby switch node(s) have amber LEDs off.
Active DS1Cs amber LEDs are on solid.
