1 Gbps LAN LEDs

The LAN ports have two LEDs. One LED indicates activity when flashing. The other LED can be green, amber or off to indicate the speed of the connection, as shown in the following figure. See the following table for the functions that are associated with the connection speed LED.

Color Speed
Off No connection or 10 Mbps
Green 100 Mbps
Amber 1 Gbps

10 Gbps LAN LEDs

The 10 Gbps LAN ports have two LEDs. One LED indicates activity when flashing while the other LED is green to indicate the existence of the connection, as shown in the following figure. The location of these LEDs can vary depending on the NIC model.

The Activity LED is to the left of the Link LED. Both are to the left of the port.

Intelligent Platform Management Interface (IPMI)

This network port allows remote administration of hardware. For a detailed description of IPMI, refer to the following Intel documentation.

Power supplies

Each power supply includes one LED with five states in the rear.

Table 2. Power supply LED states
LED state Description
Off No AC power to either power supply.
Amber Power supply critical event causing a shutdown, failure, Overcurrent Protection, Overvoltage Protection, fan failure, AC out of range, or no AC power to this PSU (only for 1 + 1 configuration)
Flashing Amber Power supply warning event where the power supply continues to operate: high temp, high power, high current, or slow fan.
Flashing Green AC present/only five standby voltage (PSU off).
Steady Green Output on and OK.

Hard disk carrier

Each drive carrier has two LEDs, one to indicate activity (green) and the other to indicate status (blue/amber).
