Table 4-1 “POST LED states” lists the HBA
LED states and describes the meaning of each state.
If the LEDs indicate a failure during POST:
Make sure the HBA is seated
firmly in the PCI slot.
Verify that the fiber cable
connection to the HBA is secure.
Check the POST LED states
listed in the Table 4-1 “POST LED states” to determine the HBA
status.
