LED During Power-up

During its power-up sequence, the controller passes through the

following states in sequence, as indicated by the LEDs:

Note: The address translation unit (ATU), PCI bridge, and

cache module (if installed) must be configured and enabled

before controller initialization can be completed. If any of

these components are not configured or become disabled

during the Fast Idle phase, the pattern reverts to the wait

pattern of the affected component.

LEDs 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.

LEDs During Controller Active

When the controller is active, the LEDs indicate any of the following

states:

Condition LED Display

Memory Mapped

I/O

LEDs 6 and 7 and LEDs 5 and 8 flash alternately

while the controller waits for the host computer to

initialize the ATU on the PCI bus.

Bridge LEDs 5 and 7 and LEDs 6 and 8 flash alternately

while the controller waits for the host computer to

initialize its PCI-to-PCI bridge.

Fast Idle After the ATU and PCI bridge have been enabled, the

controller enters a fast idle pattern while waiting for

the controller initialization commands.
