System reset
failure in
SN3420
When the front
panel reset
button is
pressed, the
system does not
respond. It
either stalls, or
continues
operating with
no reset.
Cause: The reset button is stuck in a pressed position
due to physical pressure applied by the front panel.
Solution: The suitable solution depends on the reset
reason:
1. For regular system reset, select one of the
following commands (according to your Operating
System), and run it from the CLI:
DVS OS: reboot
Sonic: reboot
Onyx: reload
Cumulus: sudo reboot
2. In case a reset is required in order to quit a sleep
mode that was activated using the halt, poweroff or
shutdown commands, the system should be power
cycled using the PDU OFF/ON command.
3. If password reset is required, please contact
NVIDIA's support team at Networking-
support@nvidia.com.
