Clear Firmware-Counters Command
DS1 converter firmware generates error reports autonomously. This takes place independently
of technician-demanded tests. The test board location clear command will not affect
the error status reported by firmware. The clear firmware-counters command clears
every on-board firmware-detected error unconditionally.
The clear firmware-counters location command sends a downlink message to the
DS1 converter 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 (#949) 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.
Downtime Required when Upgrading to
TN1654 DS1 Converter Circuit Packs
!
WARNING:
WARNING: Upgrading from TN574 DS1 converter circuit packs to TN1654 DS1 converter
circuit packs will require down time for the affected PN.
The TN1654 DS1 Converter circuit pack is not compatible with the TN573 SNI circuit pack, the
TN574 DS1 converter board, the Y-cable used to connect to the TN574 DS1 converter board or
pre-G3V5 software. All DS1 converter boards and Y-cables must be upgraded. If the PN is
remoted via a Center-Stage Switch, the connected SNI must also be upgraded. A TN573B (or
higher-suffixed) SNI board must be used when connecting to a TN1654 DS1 converter board.
Use remove fiber-link to remove the fiber-link administration for the TN574 DS1
converter complex. Use change circuit-pack show that TN1654 boards are now being
used. Then use add fiber-link to administer the TN1654 DS1 converter complex.
