System Power

Power Off

In certain situations, you might need to power off the switch instead of rebooting. To power off the switch, run the cl-poweroff command, which shuts down the switch.

cumulus@switch:~$ sudo cl-poweroff

Alternatively, you can run the Linux poweroff command, which gracefully shuts down the switch (the switch LEDs stay on). On certain switches, such as the NVIDIA SN2201, SN2010, SN2100, SN2100B, SN3420, SN3700, SN3700C, SN4410, SN4600C, SN4600, SN4700, SN5400, or SN5600, the switch reboots instead of powering off.

cumulus@switch:~$ sudo poweroff

Power Cycle

NVUE provides the nv action power-cycle system command so that you can power cycle the switch remotely to recover from certain conditions, such as a thermal ASIC shutdown due to high temperatures.

When you run the nv action power-cycle system command, the switch prompts you for confirmation before power cycling.

cumulus@switch:~$ nv action power-cycle system
The operation will Power Cycle the switch.
Type [y] to power cycle.
Type [N] to abort.

Do you want to continue? [y/N]  
Action executing ... 
Action succeeded 

To power cycle the switch without being prompted for confirmation, run the nv action power-cycle system force command:

cumulus@switch:~$ nv action power-cycle system force 
Action executing ... 
Action succeeded
