Use the following legend for both tables:
NOTE: If the reset button is flashing and an LED is lit continuously, either the devices on that
LED bus do not match the controller configuration, or an error occurred in one of the devices on
that bus.
Also, a single LED that is lit indicates a failure of the drive on that port.
Flashing OCP Pattern Display Reporting
Certain events can cause a flashing display of the OCP LEDs. The event and its resulting
patterns are described in Table 4–4.
NOTE: Reminder: a solid black pattern represents a flashing display. A white pattern indicates
