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 loc ation is entered. If the system has PNC dup lication, 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 s oftware to reset the SNC via the TPN link.
If no inserted SNIs in the same carrier as the SNC can suc cessfully reset the
SNC, software will send a reset message direc tly 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 d irectly to the SNC) will not work if the SNC is
insane.
If an active SNC is reset and a standb y SNC exists in the same switch node
carrier, the standby SNC will b ecome active. The reset board command should
not be used to make a stand by SNC active. Instead, the set switch-node-clock
UUCSS command should b e used.
If the SNC is standby and the reset board c ommand is executed, the a ctive SNC
is told by software to reset the stand by SNC via the TPN link.
An SNC should be reset instead of reseating the circuit pac k. The reset board
command should almost nev er be used on an SNC. It may be nec essary to use
the reset board command if the SNC circ uit pack gets into a m ode where it
cannot communicate with so ftware.
