Replacing an SNI Circuit Pack— Duplicated PNC
SNI-BD (SNI Circuit Pack)
WARNING: On a system with duplicated PNC synchronization may be provided over a
combination of active and standby components. This condition is indicated by an
OFF-BOARD WRN alarm against TDM-CLK with Error Type 2305. Repairs to
standby PNC in this state may disrupt service. If the active PNC is functional,
replacement of a standby component does not disrupt service.
To replace a Switch Node Interface circuit pack in an duplicated PNC:
1. Enter status pnc.
Verify that the component to be replaced is on the standby PNC.
2. Enter busyout pnc.
3. Enter busyout board location.
4. Replace the circuit pack.
5. Enter release board location.
CAUTION: Do
! CAUTION:
not busyout any Expansion Interface circuit pack after this point.
6. Enter test alarms long clear for category exp-intf.
7. Wait 5 minutes for SNI-BD, SNI-PEER, FIBER-LK, and DS1C alarms to clear, or enter
clear firmware-counters sp 0 a-pnc | b-pnc.
Use the letter designation of the pnc which holds the replaced component (the standby
pnc).
8. Enter status pnc.
If either PNC’s state of health is not “functional”, consult PNC-DUP (PNC Duplication).
9. Enter release pnc.
Switch Node Interface Manual Loopback Procedure
This procedure is destructive.
Use this procedure when an SNI circuit pack cot be tested by software. This can occur when
communication between the switch node carrier and the server is down. Before using this
procedure, use test board location to run the Configuration Audit (#759) on SNI circuit
packs where possible. Also, use test board location long to run the Processor Route
Audit Test (#760) for the active SNC in the switch node carrier. If the active SNC is not inserted,
use test hardware-group pnc P, where P is a-pnc or b-pnc to run Test #760.
