You can power off or restart any ESXi host by using the vSphere Web Client. Powering off a managed host disconnects it from vCenter Server, but does not remove it from the inventory.
- In the vSphere Web Client, navigate to the host that you want to shut down.
- Power off all virtual machines on the host.
- Right-click the host and select Reboot or Shutdown.
If you select Reboot, the ESXi host shuts down and starts.
If you select Shut Down, the ESXi host shuts down. You must manually power the system back on.
- Provide a reason for the shut down.
