Function
On the Power Control page, you can perform power-on, normal power-off, cold reset or forced reset,forced power off, and send non-maskable interrupts (NMIs) for compute nodes and switch modules, and graceful reboot or forced power cycles of compute nodes. The planes of switch modules are described as follows:
- Base: specifies the GE switching plane.
- Fabric: specifies the 10GE switching plane.
- FC: Specifies the FC plane.
You can perform the following power control operations:
- Power On
- Normal Power Off
- Cold Reset (or Forced System Reset)
- Graceful Reboot (or Forced Power Cycle): The internal process for gracefully rebooting a compute node is as follows: shutting down the operating system (OS), powering off the compute node, and then powering on the compute node.
- NMI: This button triggers a server to generate a non-maskable interrupt. Click this button only when the OS is abnormal. Do not click this button when the server is operating properly. If you click this button, the OS cannot be normally shut down.
NOTE: The CH242 does not support NMI.
- Forced Power Off
NOTE: It takes 10 minutes to wait for the OS shutdown on a compute node during a Forced Power Cycle by default. If the OS has not been shut down after 10 minutes, the compute node is directly powered off and then powered on. The waiting time is configurable on the BMC web user interface (WebUI) of the compute node.
