Switch & LED
Power
Switch
Power
LED
The power switch turns the Netserver power On or Off. If sleep states are
available, it also transitions between Power On and sleep states.
Sleep states are NOS dependent and not available if your NOS does not
support power management based on the ACPI (Advanced Configuration and
Power Interface) standard. Refer to “Applying Power to the HP Netserver” and
“Sleep States (ACPI)” later in this chapter.
The LED indicates the power state of the Netserver:
•
• •
• Steady Green indicates the Netserver is operating normally
•
• •
• Blinking Green indicates the Netserver is in a sleep state and under
ACPI control
•
• •
• Off (unlit) indicates the Netserver is powered off or in standby mode
Reset Switch
RESET
This switch creates a hard system reset, which is equivalent to a power-on
reset.
