HBA LEDs

There are six LEDs on the front of the enclosure. For each port, there is one green Activity LED and one yellow Fault LED that indicate any activity or fault of a Phy in that port. There is also one green Power LED and one yellow Attention LED on the HBA. The Power and Attention LEDs are both controlled by the host system and show through the PCIe ExpressModule enclosure and functionality (see Attention and Power LEDs for the HBA ).
