Column 1 PCI Express Lane Good indicator LEDs (LANE0..3)

Four discrete GREEN LEDs provide an indication of the status of the PCI Express lanes. In the case of a

1X card only LANE0 should be lit.

LANE0 – D13, Illuminated when Lane 0 of the PCI-Express bus is active.

LANE1 – D14, Illuminated when Lane 1 of the PCI-Express bus is active.

LANE2 – D15, Illuminated when Lane 2 of the PCI-Express bus is active.

LANE3 – D16, Illuminated when Lane 3 of the PCI-Express bus is active.

Column 2 PSOC controlled

This group of two discrete GREEN LEDs indicates the status of the PSOC controller.

Heartbeat – D17, Pulses when the firmware is running.

Error. – D11, Indicates when the +12V power is out of spec. or the fan is stalled.

Note that during the boot load process both the Heartbeat and Error LEDs blink

Column 4 Voltages group (+3.3V,+5V, +12,-12V)

This group of four discrete GREEN LEDs indicates the presence of power voltages.

+3.3V: D3, When illuminated shows presence of PMC +3.3V from the DC/DC converter.

+5V: D4, When illuminated shows presence of +5V to PMC card from the DC/DC converter.

+12V: D5, When illuminated shows presence of PCI Express +12V from the motherboard.

-12VPMC: D6, When illuminated shows presence of -12V to PMC card from the DC/DC converter.

+3.3V AUX: D7, When illuminated shows presence of PMC +3.3V AUX from the host.

When one of the above LEDs is not illuminated, the corresponding supply should be checked for proper

setting. Since these LEDs are connected directly to the power supplies they do not indicate that the power

supply voltages are within spec.

Note that V3Aux is an optional supply that might not be present on the PCI Express bus.
