LEDs
•
Power LED (green). This LED is controlled by software. It flashes when the server is first powered up and
changes to steady on when the server firmware has completed the power-up self-test (POST).
•
NIC1 and NIC2 LEDs (green). These LEDs blink to reflect network data activity.
•
System Status/Fault LED (green/amber). This LED can assume different states (green, amber, steady, blinking)
to indicate critical, non-critical, or degraded server operation. See “Front-Panel System Status LED” on page 6-3
for more details regarding this LED.
•
Hard Disk Drive Activity LED (green). The Drive Activity LED on the front panel is used to indicate drive
activity from the onboard SCSI controller. The server Main Board also provides a header, giving access to this
LED for add-in IDE or SCSI controllers.
•
System ID LED (blue). The blue System Identification LED is used to help identify a system for servicing when
it is installed within a high density rack or cabinet that is populated with several other similar systems. The
System ID LED is illuminated when the system ID button, located on the front panel, is pressed. If activated by
the front panel pushbutton, the LED remains on until the pushbutton is depressed again. The LED also
illuminates when the server receives a remote System Identify command from a remote management console. In
this case, the LED turns off after a timeout period. An additional blue System ID LED on the Main Board is
visible through the rear panel. It mirrors the operation of the front panel LED.
Pushbuttons
•
Power/Sleep button. This pushbutton is used to toggle the system power on and off. This button is also used as a
sleep button for operating systems that follow the ACPI specification. Sun Linux configures the power button to
the instant off mode.
•
Reset button. Depressing this pushbutton reboots and initializes the system.
•
NMI button. Pushing this recessed pushbutton causes a non-maskable interrupt to occur; however, NMI event
trapping is not implemented in Sun Linux 5.0.
•
System ID button. This pushbutton toggles the state of the front panel ID LED and the server Main Board ID
LED. The Main Board ID LED is visible through the rear of the chassis and allows you to locate a particular
server from behind a rack of servers.
