Mini Control Panel LED Indicators

The control panel houses three LEDs to display the system's operating state. The LEDs are
visible with or without the front bezel.
The following table identifies each LED and describes their functionality:

System Status
B

Power/Sleep
C
(on standby power)
Notes:
1. Blink rate is ~1 Hz at 50% duty cycle.
2. The amber status takes precedence over the green status. When the amber LED is on or blinking, the
green LED is off.
3. The power LED sleep indication is maintained on standby by the chipset. If the system is powered
down without going through the BIOS, the LED state that is in effect at the time of power off is restored
when the system is powered on until the BIOS clears it. If the system is not powered down normally, it
is possible that the power LED is blinking while the system status LED is off. This is due to a failure or
configuration change that prevents the BIOS from running.

Table 42. Mini Contol Panel Button Functions
Toggles the front panel ID LED and the server board ID LED on/off. The
server board ID LED is visible through the rear of the system and allows for
server identification and location when working behind a rack of servers.
Pressing the recessed button with a paper clip or pin puts the server in a
halt state for diagnostic purposes and allows the issuance of a
non-maskable interrupt. After issuing the interrupt, a memory download can
be performed to determine the cause of the problem.
Toggles the system power on/off. This button also functions as a sleep
button if enabled by an ACPI-compliant operating system.
