4. Remove the B-PNC fibers by removing the Endpoint Board Locations on the change
fiber-link screen for all fibers. For fibers using DS1Cs, remove the B-PNC DS1C
Board Locations on the change fiber-link screen.
5. Remove the B-PNC circuit packs starting with the switch node carrier most distant from the
media server complex. Use change circuit-pack location, 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 location 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
screen by changing PNC Duplication to no.
If an alarm exists against any Expansion Interface circuit pack connected to a B-PNC
carrier, use test board location 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.
