SmartRAID VI Controller LEDs
SmartRAID VI controllers provide nine LEDs that let you visually
monitor controller activity. Several different controller states are
indicated by the LED as outlined in the following sections. Two
additional LEDs indicate the status of the cache memory on the
controller. See Appendix A, "Assembly Drawings" for the location of the
LEDs on your controller.
LED Display During Power-Up
During its power-up sequence, the controller passes through the
following states in sequence, as indicated by the LEDs:
Memory Mapped I/O LEDs 6 and 7 and LEDs 5 and 8 flash alternately

configured and enabled before the I
completed. If any one of these components are not configured
or become disabled during the Fast Idle phase, the pattern will
return to the respective wait pattern for the affected
component.
LED Display During Controller Idle
When no commands are in progress and all bus activity has ceased, the
controller enters the Idle state. This is indicated by a rotating pattern in
LEDs 1 through 8.
