Spirent TestCenter: Can I change a setting on the SPT-N11U chassis to reboot itself after a power failure?
Environment/Versions
SPT-N11U
SPT-N12U
SPT-N4U
PX3-QSFP-DD-8
A1-QD-400
A2-QD-400
Odin 800G
Answer
You can change a setting in the BIOS on the SPT-N11U and N4U controller by doing the following:
Connect a USB Keyboard and Monitor to the controller
Power cycle the chassis
Press the F2 key to enter the BIOS as it is booting
NOTE: No password is required to access BIOS in a N11U chassis
Go to the Power tab
There is a powerup selection for power off, power on, or last state
Select the last state option and if the chassis was on before the power outage it will boot back up automatically, if it was off it will stay off
Save and exit the BIOS
Note: This does not apply to the SPT-11U chassis, there isn't a way to get the SPT-11U to come up automatically after a power outage.

Video of the procedure to go through the BIOS menu.
Press ESC while it’s booting up.
Go to Setup Utility -> AMD CBS -> FCH Options -> AC Power Loss Options.
Select Always On
The HW team has verified the Always On mode works as expected.
Always Off makes it so that even the BMC doesn’t power on after AC power loss.
For ODIN 800G
The ODIN specialized team, found the following power options on the BIOS
ACPI S3:
The ACPI S3 state, also known as Suspend to RAM, offers a sleep mode with rapid wake-up capability. This state is quite similar to the S1 sleep state, with the distinction that the CPU and system cache context are not retained. Instead, the operating system takes responsibility for managing these caches and the CPU context. Upon waking up from this state, control initiates from the processor's reset vector. In certain systems, such as NCR setups, during S3, power is solely directed to the USB 3.0 ports.
It's important to note that when resuming from an S3 state, all connected USB devices undergo a re-enumeration process. This can result in speaker tones resembling disconnection and reconnection sounds. However, this behavior doesn't pose any issues, and the USB devices will continue to function correctly.
Wake on PME:
The Wake on PME protocol enables remote activation of a computer that is turned off, suspended, or in hibernation. This is achieved by transmitting a remote signal via the Internet. Once detected by the computer, this signal triggers the computer's power-on sequence.
Wake on Modem Ring:
The Wake on Modem Ring specification permits supported devices and computers to transition from sleep, hibernation, or a "soft off" state (like ACPI states G1 or G2) to an operational state upon receiving a specific signal, such as a modem ring.
Auto Wake on S5:
The Auto Wake on S5 setting empowers users to configure their computer to wake up from the S5 state, also known as Soft Off. In this state, the power supply remains active but doesn't distribute power to other system components. Users can establish schedules for the system to execute a soft reboot at designated times.
S5:
The S5 state signifies the shutdown or powered-off status of the system.
