Sun[tm] Fire V60x and V65x LEDs

Front Panel LEDs

LED	Color	Function
Power	Green	This LED is controlled by software. It turns steady when the server is powered up. Off when the system if off or in sleep mode.
NIC1 and NIC2	Green	These LEDs are on when a good network link has been established. They blink green to reflect network data activity.
System Status/Fault	Green/Amber	This LED can assume different states (green, amber, steady, blinking) to indicate critical, non-critical, or degraded server operation. Steady green: Indicates the system is operating normally Blinking green: Indicates the system is operating in a degraded condition. Blinking amber: Indicates the system is in a non-critical condition. Steady amber: Indicates the system is in a critical or non-recoverable condition. Off: Indicates POST/system stop. See Front-Panel System Status LED for more details regarding this LED.
Hard Disk Drive Activity	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. Blinking green (random): Hard disk activity Steady amber: Hard disk fault Off: No disk activity nor fault condition (or power is off).
System ID	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.

Front-Panel System Status LED

Critical Condition

A critical condition or non-recoverable threshold crossing is indicated with a continuous amber status LED and is associated with the following events:

Temperature, voltage, or fan critical threshold crossing.
Power subsystem failure. The Baseboard Management Controller (BMC) asserts this failure whenever it detects a power control fault (for example, the BMC detects that the system power is remaining on even though the BMC has deasserted the signal to turn off power to the system).
The system is unable to power up due to incorrectly installed processor(s), or processor incompatibility.
A satellite controller such as the HSC, or another IMPI-capable device, such as an add-in server management PCI card, sends a critical or non-recoverable state, via the Set Fault Indication command to the BMC.
Critical Event Logging errors, including System Memory Uncorrectable ECC error and Fatal/Uncorrectable Bus errors, such as PCI SERR and PERR.

Non-Critical Condition

A non-critical condition is indicated with a blinking amber status LED and signifies that at least one of the following conditions is present:

Temperature, voltage, or fan non-critical threshold crossing.
Chassis intrusion.
Satellite controller sends a non-critical state, through the Set Fault Indication command, to the BMC.
A Set Fault Indication command from the system BIOS. The BIOS may use the Set Fault Indication command to indicate additional, non-critical status such as system memory or CPU configuration changes.

Degraded Condition

A degraded condition is indicated with a blinking green status LED and signifies that at least one of the following conditions is present:

Non-redundant power supply operation. This only applies when the BMC is configured for a redundant power subsystem. The power unit configuration is configured via OEM SDR records.
A processor is disabled by FRB or BIOS.
BIOS has disabled or mapped out some of the system memory.

Refer to the Sun Fire V60x and Sun Fire V65x servers Troubleshooting Guide for information on how to isolate the server component responsible for any of the critical, non-critical, or degraded conditions listed above.

Rear Panel LEDs

LED	Color	Function
Network Connection/ Network Activity	Green	This LED is on the left side of each NIC connector. Green = valid network connection. Blinking = transmit or receive activity.
Network Speed	Amber/Green	This LED is on the right side of the NIC connector. Off = 10 Mbps operation. Green = 100 Mbps operation. Amber = 1000 Mbps operation.
POST LEDs (four)	Multicolor (Red/Green/Amber)	To help diagnose power-on self test (POST) failures, a set of four bi-color diagnostic LEDs is located on the back edge of the server Main Board. These LEDs are visible through holes in the rear panel. Each of the four LEDs can have one of four states: Off, Green, Red, or Amber. For detailed information on these LEDs, see POST LED Indicators.
System ID	Blue	This LED is located on the Main Board and is visible through holes in the rear panel. It can provide a mechanism for identifying one system out of a group of identical systems. This can be particularly useful if the server is used in a rack-mount chassis in a high-density, multiple-system application. The LED is activated by depressing the front panel System ID pushbutton or if the server receives a remote System Identify command from a remote management console. If activated by the front panel pushbutton, the LED remains on until the pushbutton is depressed again. When the LED illuminates due to a remote System Identify command, the LED turns off after a timeout period. An additional blue System ID LED is located on the front panel that mirrors the operation of the rear Main Board LED.
System Status/Fault	Green/Amber	This LED reflects the state of the System Status LED on the front panel.
Power Supply	Green/Amber	This is a bi-color LED that can be on, off, green, amber, or blinking, or combination thereof. See Rear Panel Power Supply Status LED for more detailed information.

Rear Panel Power Supply Status LEDs

Power Supply LED State	Power Supply Condition
OFF	No AC power present to power supply
BLINKING GREEN	AC power present, but only the standby outputs are on
GREEN	Power supply DC outputs on and OK
BLINKING AMBER	PSAlert# signal asserted, power supply on
AMBER	Power supply shutdown due to over current, over temperature, over voltage, or undervoltage
AMBER or OFF	Power supply failed and AC fuse open or other critical failure

Note - If redundant power supplies are used in the Sun Fire V65x server, the power supply LEDs have the following meaning:

Both LEDs off = no power to power supplies or both power supplies bad
Both LEDs blinking green = power supplies receiving AC power, but server is off
Both LEDs solid green = server is fully powered on and power supplies are good
One LED solid green and one LED amber = AC power missing from one of the power supplies

POST LED Indicators

To help diagnose POST failures, a set of four bi-color diagnostic LEDs is located on the back edge of the server Main Board. Each of the four LEDs can have one of four states: Off, Green, Red, or Amber.

The LED diagnostics feature consists of a hardware decoder and four dual color LEDs. During boot block POST and post boot block POST, the LEDs display all normal Port80 codes representing the progress of the BIOS POST. Each POST code is represented by a combination of colors from the four LEDs. The LEDs are in pairs of green and red. The POST codes are broken into two nibbles, an upper and a lower nibble. Each bit in the upper nibble is represented by a red LED and each bit in the lower nibble is represented by a green LED. If both bits are set in the upper and lower nibble then both red and green LEDs are lit, resulting in an amber color. Likewise, if both bits are clear then the red and green LEDs are off.

During the POST process, each light sequence represents a specific Port-80 POST code. If a system should hang during POST, the diagnostic LEDs present the last test executed before the hang. When you read the LEDs, observe them from the back of the system. The most significant bit (MSB) is the leftmost LED, and the least significant bit (LSB) is the rightmost LED.

Note - When comparing a diagnostic LED color string from the server Main Board to those listed in the diagnostic LED decoder in the following tables, the LEDs on the Main Board should be referenced when viewed by looking into the system from the back. Reading the LEDs from left to right, the most-significant bit is located on the left.
