Shutting off system power
▼Powering down
If you need to power off the appliance, you can proceed in any of three ways, depending on the circumstances.
1.Under normal circumstances, power off the server gracefully by using a stylus to press and release the power button on the front panel.
This is the normal way you shut down the VTL server. Pressing and releasing the power button causes the Advanced Configuration and Power Interface (ACPI) to stop the operating system in an orderly fashion before shutting main power off. It places the system in standby power mode. The OK LED on the front panel starts blinking.
2.In an emergency, power off the server immediately by using a stylus to press and hold the power button for four seconds.
This shuts the main power off and places the system in standby power mode. The OK LED on the front panel starts blinking.
3.Then, if you need to power off the appliance completely, so that neither the server nor the service processor draws power, unplug the AC power cords from the power supplies at the rear of the server.
The OK LED on the front panel is not lighted.
