10.1.9.1. Initialization Issues
The
stack_fault_cell_wdt
,
stack_fault_therm_wdt
,
stack_fault_ci_wdt
, and
stack_fault_open_wire_wdt
can
be uninitialized due to problems with the Link Bus. Refer to
The
sc_fault_pi_afe_wdt
and
stack_fault_power_wdt
can be uninitialized due to disabling the Stack
Switchgear unit’s internal Power Interface module’s AFE or a high amount of noise on the DC bus.
This is typically caused by incorrectly modifying the Stack Switchgear factory configuration file.
Contact
for a valid configuration file for the Stack Switchgear.
The
sc_fault_controller_wdt
can be uninitialized if there is no external controller updating the
heartbeat. Contact
to update the configuration file
