Switch Node Clock Reset Test (#780)
This test is destructive
.
This test resets the SNC circuit pack via the
reset board UUCSS
command when
an SNC circuit pack location is entered. If the system has PNC duplication, the
active SNC on the active PNC cannot be reset.
If the SNC is active and the
reset board
command is executed, an SNI in the
same carrier as the SNC will be told by software to reset the SNC via the TPN link.
If no inserted SNIs in the same carrier as the SNC can successfully reset the
SNC, software will send a reset message directly to the SNC. Software first tries
to reset the SNC via an SNI in case the SNC is insane because the latter method
(sending the reset message directly to the SNC) will not work if the SNC is
insane.
If an active SNC is reset and a standby SNC exists in the same switch node
carrier, the standby SNC will become active. The
reset board
command should
not be used to make a standby SNC active. Instead, the
set switch-node-clock
UUCSS
command should be used.
If the SNC is standby and the
reset board
command is executed, the active SNC
is told by software to reset the standby SNC via the TPN link.
An SNC should be reset instead of reseating the circuit pack. The
reset board
command should almost never be used on an SNC. It may be necessary to use
the
reset board
command if the SNC circuit pack gets into a mode where it
cannot communicate with software.
