Clear Firmware-Counters Command
DS1 CONV 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 all on-board firmware-detected
errors unconditionally.
The
clear firmware-counters
UUCSS command sends a downlink message to
the DS1 CONV 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 CONV Circuit Packs
!
WARNING:
Upgrading from TN574 DS1 CONV circuit packs to TN1654 DS1 CONV
circuit packs will require down time for the affected EPN.
The TN1654 DS1 Converter circuit pack is not compatible with the TN573 SNI
circuit pack, the TN574 DS1 CONV board, the Y-cable used to connect to the
TN574 DS1 CONV board or pre-G3V5 software. All DS1 CONV boards and
Y-cables must be upgraded. If the EPN is remoted via a Center-Stage Switch, the
connected SNI must also be upgraded. A TN573B or later suffix SNI board must
be used when connecting to a TN1654 DS1 CONV board.
The fiber-link administration for the TN574 DS1 CONV Complex must be removed
via the remove fiber-link command. The change circuit-pack form must be
updated to reflect that TN1654 boards are now being used. The TN1654 DS1
CONV Complex can then be administered via the add fiber-link command.

WARNING:
Do not power down a Switch Node carrier to replace a circuit pack.
