Intel® Server Systems SR1530SH and SR1530HSH Front Control Panel 5.1.1 Power/Sleep LED Table 18. SSI Power LED Operation State Power Mode LED Power Off Non-ACPI Off Description System power is off and the BIOS has not initialized the chipset. Power On Non-ACPI On System power is on but the BIOS has not initialized the chipset. S5 ACPI Off Mechanical is off and the operating system has not saved any context to the hard disk. S4 S3-S1 ACPI ACPI Off Slow blink 1 Mechanical is off, and the operating system has saved context to the hard disk. DC power is still on. The operating system has saved context and gone into a level of low-power state. S0 ACPI Steady on System power is on and the operating system is up and running. Note: 1. The blink rate is ~ 1Hz with at 50% duty cycle. 5.1.2 System Status LED The system status LED is a bi-color (two colors) LED. Green (status) is used to show a normal operation state or a degraded operation. Amber (fault) shows the platform hardware state and overrides the green status. The system status LED is controlled by the BMC. Early in the startup boot process, the BIOS checks the chipset for any memory errors. Note: BIOS detected errors do not affect the system status LED. The BMC-detected states are included in the LED states. For fault states monitored by the BMC sensors, the contribution to the LED state follows the associated sensor state with priority given to the most critical asserted state. When the server is powered down (transitions to the DC-off state or S5), the BMC is still on standby power and retains any front panel status LED faulted state established before the power-down event. Note that only fault conditions for sensors monitored in both power on and power off states are retained in the DC-off state. If there are no fault conditions present at DCoff, the status LED is turned off. 5.1.3 Drive Activity LED The drive activity LED on the front panel indicates drive activity from the onboard hard disk controllers. The Intel® Server Board S3200SH also provides a header with access to this LED for add-in controllers. Revision 1.3 Intel order number: E23177-003 25

System Status LED
The system status LED is a bi-color (two colors) LED. Green (status) is used to show a normal
operation state or a degraded operation. Amber (fault) shows the platform hardware state and
overrides the green status. The system status LED is controlled by the BMC. Early in the startup
boot process, the BIOS checks the chipset for any memory errors.
Note:
BIOS detected errors do not affect the system status LED.
The BMC-detected states are included in the LED states. For fault states monitored by the BMC
sensors, the contribution to the LED state follows the associated sensor state with priority given
to the most critical asserted state.
When the server is powered down (transitions to the DC-off state or S5), the BMC is still on
standby power and retains any front panel status LED faulted state established before the
power-down event. Note that only fault conditions for sensors monitored in both power on and
power off states are retained in the DC-off state. If there are no fault conditions present at DC-
off, the status LED is turned off.

Drive Activity LED
The drive activity LED on the front panel indicates drive activity from the onboard hard disk
controllers. The Intel
®
Server Board S3200SH also provides a header with access to this LED
for add-in controllers.
