Generation 6 LEDs

The LEDs provide the status information of the server and the activity on its ports.

Power supply status LED

To indicate power supply status, there is a single bi-color LED. The LED operation is defined as:

Trellix ESM power supply indicator light states

Color	State	Status
Green	Solid	Power supply is ON
Green	Blinking	Power supply is plugged in and turned off by the system.
Amber	Solid	Power supply is plugged in, and is in an abnormal state. The system might need service.
Amber	Blinking	Power supply continues to operate with warning events: High temperature High power High current Slow fan
Off	Off	No AC power to all power supplies

External RJ45 NIC Port LED

Each LAN has one bi-colored LED per port (RJ45 or SFP+) at the bottom of PCB. The LEDs indicates link speed.

LED Color	Description
Amber	The data rate is <12Gbps
Green	The data rate is 12Gbps

System Status LED

Indicate the current health of the server system.

Color	State	Description
Red	Solid on	An overheating condition has occurred
Red	Blinking at 1Hz	Fan failure, check the inoperative fan
Red	Blinking at 0.25Hz	Power failure, check the non-operational power supply
Red	Blinking at 10Hz	CPLD recovery mode error
Red	blinking at 10Hz and the rear UID LED is blue, blinking at 10Hz	CPLD recovery or update is in progress
Blue	Solid	Unit ID is activated by the switch
Blue	Blinking at 1Hz	Unit ID is activated by the BMC
Blue	Blinking at 2Hz, and BMC Heartbeat LED on the motherboard is green	BMC is resetting
Blue	Blinking at 4Hz	BMC is resetting factory defaults
Blue	Blinking at 10Hz	BIOS/BMC is recovering or updating

Drive Activity and Status LED

Each drive carrier includes separate LED indicators for drive Activity and drive Status.

	Color	State	Behavior of device
Status LED	Off		Idle SATA drive installed
	Blue	Solid on	Idle SAS drive installed
	Blue	Blinking pattern	I/O activity

	Condition	Drive Type	Behavior
Green	Turn on with no drive activity	SAS	LED stays on
	Turn on with no drive activity	SATA	LED stays off
	Turn on with drive activity	SAS	LED blinks off when processing a command
	Turn on with drive activity	SATA	LED blinks on when processing a command
	Turn on and drive spun down	SAS	LED stays off
	Turn on and drive spun down	SATA	LED stays off
	Turn on and drive spinning up	SAS	LED blinks
	Turn on and drive spinning up	SATA	LED stays off

Power button

Toggles the system turn on and off.

LED	State	Description
Green	Solid	System power is on.
Green	Blinking at 4Hz	BMC/BIOS checking
Red	Blinking (2 blinks red) at 4Hz, 1 pause at 2Hz (on-on-off-off)	BMC recovery or update is in progress
Green	Blinking at 1Hz	BMC/BIOS flash not detected

BMC Boot or Reset Status LED indicators

A baseboard management controller (BMC) boot occurs when AC power is first applied to the system. A BMC reset occurs after a BMC FW update, on receiving a BMC cold command, and on a BMC watchdog initiated reset.

BMC Boot or Reset State	UID LED	State	Status LED
BMC reset	Blue	Blinks at 2Hz	Solid Green
Restore defaults	Blue	Blinks at 4Hz	Off
Update	Blue	Blinks at 10Hz	-
