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.
