Chassis Front Controls and Indicators

A. Power On/Off button: When activated by momentary contact while the system is off, this
button turns the power subsystem on. If the system is in sleep state, activating the button
by momentary contact brings the system out of sleep state. If you press the button down
for more than four seconds, you override ACPI mode and the power is turned off.
B. Reset button: When activated by momentary contact, this button resets the system. If the
reset button is pushed for four seconds or more, the power button is pushed, and then
both the reset and power buttons are released within one second of each other, the
CMOS is cleared.
C. Sleep button: When activated by momentary contact, this button puts an operating
system supporting ACPI mode to sleep (S1). When activated by momentary contact
during sleep state, the operating system becomes active. This system does not have a
service mode.
D. Front panel LEDs from left to right:
D0 General System Fault LED: Yellow indicates a system failure.
D1 NIC activity LED: Green indicates NIC activity.
D2 HDD activity LED: Green indicates any system hard drive activity.
D3 Main Power LED: Solid green indicates the presence of DC power in the server.
