SNC-BD (Switch Node Clock Circuit Pack)
Issue 1 May 2002
8-1387
555-233-143
The clear firmware-counters UUCSS command sends a downlink message to
the SNC circuit pack, causing it to clear out its firmware error counters and failure
database. 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 SNC Circuit Packs
!
WARNING:
Do not power down a Switch Node carrier to replace a circuit pack.
Replacing an SNC on a system with unduplicated SNCs disrupts service.
High-Reliability System (Duplicated Server
and SNCs, Unduplicated PNC)
This procedure is nondestructive.
1. If the SNC circuit pack to be replaced is the active SNC in the switch node
carrier (yellow LED is on solid), first set the standby SNC to active via the
set switch-node-clock command.
2. When the SNC circuit pack is in standby mode (yellow LED is off), pull out
the SNC circuit pack to be replaced.
3. Insert a new SNC circuit pack.
4. Wait for the SNC to reset. (The red and green LEDs light and then go out.)
The yellow LED should be off since the SNC circuit pack is in standby
mode.
