SNI-BD (SNI Circuit Pack)
Issue 1 June 2005 2051
Clear Firmware-Counters Command
SNI firmware generates error reports autonomously. This takes place independently of
technician-demanded tests. Therefore, test board location clear does not affect the error
status reported by firmware. The clear firmware-counters command clears every
firmware-generated error unconditionally.
The clear firmware-counters location command sends a downlink message to the
SNI circuit packs, causing them to clear out their firmware error counters and failure databases.
Once the firmware failure database is cleared, the failure audit test (#777) will pass. If problems
still exist, the firmware will increment its error counters and the failure audit test will begin failing
again.
Do not use this command instead of the repair procedures associated with the hardware error
log entries. This command may be useful if a problem was fixed and off-board alarms
associated with the problem are still active.
Replacing SNI Circuit Pack—Unduplicated PNC
!
WARNING:
WARNING: Do not power down a Switch Node carrier to replace a circuit pack.
!
WARNING:
WARNING: Replacing a Switch Node Interface circuit pack on an unduplicated PNC disrupts
service. This service effect can cause an outage of a single PN.
To replace a Switch Node Interface circuit pack in an unduplicated PNC:
1. Enter busyout board location.
2. Replace the circuit pack.
3. Wait for the circuit pack to reset.
Red and green LEDs will light and then go out.
4. Enter release board location.
!
CAUTION:
CAUTION: Do not busyout any Expansion Interface circuit pack after this point.
5. Enter test alarms long clear for category exp-intf.
6. Wait 5 minutes for SNI-BD, FIBER-LK, and DS1C-BD alarms to clear, or enter clear
firmware-counters a-pnc.
