Maintenance-Object Repair Procedures
Clear Firmware-Counters Command
SNI firmware generates error reports autonomously. This takes place
independently of technician-demanded tests. Therefore, the test board UUCSS
clear command will not affect the error status reported by firmware. The clear
firmware-counters command will clear every firmware-generated error
unconditionally.
The clear firmware-counters UUCSS 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.
This command should not be used as a replacement for the repair procedures
associated with the hardware error log entries. This command may be useful if a
problem has been fixed and off-board alarms associated with the problem are still
active.
Replacing SNI Circuit Pack
!
WARNING:
Do not power down a Switch Node carrier to replace a circuit pack.
!
WARNING:
Replacing a Switch Node Interface circuit pack on a simplex system
(eh???) disrupts service. This service effect can cause an outage of a single
EPN.
1. Enter busyout board UUCSS.
2. Replace the circuit pack.
3. Wait for the circuit pack to reset.
4. Enter release board UUCSS.
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.

Unduplicated PNC
UUCSS represents the cabinet-carrier-slot address
of the circuit pack to be replaced.
Red and green LEDs will light and then go out.
!
CAUTION:
Do not busyout any Expansion Interface
circuit pack after this point.
