1.Make sure that you have exited all applications.
2.Use the shut down command in your operating system’s Start menu (for Windows NT 4.0 and Windows 2000, and Windows XP operating systems).
3.When prompted, press the power button on the HP Server.
WARNING The power supply will continue to provide standby current to the Server until the power cord is disconnected from the rear panel.
If you want to force the HP Server to shut down (for example after the operating system has crashed), press and hold down the power button for approximately 5 seconds.
Connecting Power to
The HP Server temporarily draws a large “inrush current,” when first connected to an AC power source. This also occurs when the Server is in a standby mode (power is turned off, but the power cord is plugged into AC power). The inrush current is much greater than the Server’s normal operating current and generally, the AC power source can handle the normal inrush current.
However, if you install several HP Servers on one circuit, precautions are necessary. If there is a power failure and power is then restored, all the servers immediately begin to draw inrush current at the same time. If the circuit breakers on the incoming power line have insufficient capability, the breaker may trip and thus prevent the servers from powering up.
When preparing your site for installation, allow for the additional inrush current. Refer to Chapter 9.
Sleep States (ACPI)
The HP Server supports the ACPI (Advanced Configuration and Power Interface) standard, which is a key component of a NOS’s directed power management. The supported features are only available when an

The HP Server’s power button can be configured to initiate a graceful shutdown or “soft off” of the NOS rather than an immediate shutdown of the power supply. The power button configurations are dependent on
