Reboot or Shut Down an Appliance
Administration > Tools > Reboot > Appliance Reboot / Shutdown
The appliance supports three types of reboot:

Reboot: Reboots the appliance gracefully. This is your typical “vanilla” restart.
Use case: You are changing the deployment mode or other configuration parameters that require a reboot.
Erase Network Memory and Reboot: Erases the Network Memory cache and reboots the appliance.
Use case: You need to restart the appliance with an empty Network Memory cache.
Shutdown:关闭电器,关机. To restart, go to the appliance and physically turn the power on with the Power switch.
Use cases:
You are decommissioning the appliance.
You need to physically move the appliance to another location.
You need to re-cable the appliance for another type of deployment.
Behavior During Reboot
A physical appliance enters into one of the following states:
hardware bypass, if deployed in-line (Bridge mode)
open-port state, if deployed out-of-path (Router mode or Server mode)
Unless a virtual appliance is configured for a high availability deployment, all flows are discontinued during reboot.
