Technical Product Specification
Front Panel Control and Indicators IntelĀ® Server System SR1695WB TPS
Revision 1.4 35
Intel order number: E92079-005
LED Indicator Color Condition What it describes
- Off Power Off /ACPI S5 state
LAN 1 and LAN 2 Green On LAN Link no Access
Green Blink LAN Activity
- Off No Link
System ID Blue On Identify Active via command or button
- Off No Identification
System Status Green On System Ready/No Alarm
Green Blink System ready, but degraded: redundancy lost such
as the power supply or fan failure; non-critical
temp/voltage threshold; battery failure; or predictive
power supply failure.
Amber On Critical Alarm: Critical power modules failure, critical
fans failure, voltage (power supply), critical
temperature and voltage
Amber Blink Non-Critical Alarm: Redundant fan failure, redundant
power module failure, non-critical temperature and
voltage
- Off Power off: System unplugged
Power on: System powered off and in standby, no
prior degraded\non-critical\critical state
Note:
Blink rate is ~1 Hz at 50% duty cycle.
It is also off when the system is powered off (S5) or in a sleep state (S1).
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 in effect at the time of power off is restored when the system is powered
on until the BIOS clear it.
If the system is not powered down normally, it is possible the Power LED will blink at the same time the system
status LED is off due to a failure or configuration change that prevents the BIOS from running.

Note: Blink rate is ~ 1Hz at 50% duty cycle.
State Power Mode LED Description
Power Off Non-ACPI Off System power is off and the BIOS has not initialized the chipset.
Power On Non-ACPI Solid On System power is on but the BIOS has not yet initialized the
chipset.
S5 ACPI Off Mechanical is off and the operating system has not saved any
context to the hard disk.
S1 Sleep ACPI Blink DC power is still on. The operating system has saved context and
gone into a level of low-power state.
S0 ACPI Solid On System and the operating system are up and running.
