Removing Fiber Connectivity to an PN
This procedure covers removing the connectivity to an PN or between SNs.
Removing an PN and its associated carrier and circuit packs can be handled on a
board-type basis.
If this system is duplicated, start with step 1; otherwise, start with step 6.
NOTE:
The procedure below is generic in its scope. Check the customer’s switch
configuration for EI/SNI structures.
!
WARNING:
Do not power down a Switch Node carrier to replace a circuit pack.
!
WARNING:
In duplicated PNC configurations, one DS1-CONV complex in the fiber-link
serves as the active and the second DS1-CONV complex serves as the
standby. Each DS1Converter complex consists of two TN574 or TN1654
circuit packs.

1. status pnc Verify that the A-side is active.
a. If the B-PNC is active, enter reset
pnc-interchange and press
Enter.
b. Then verify that the A-side is active
(status pnc).
2. busyout pnc standby Busyout the duplicated switch side.

4. list fiber link List administered fiber connections by number.
Record the endpoints (EIs, SNIs, and DS1Cs), and
fiber link numbers that you are removing.
5. busyout fiber link n Busyout the fiber link of interest. The fiber link
number (step 4) is n for this command.
6. remove fiber link n Remove the link administration for this link.
