Adaptec RAID Installation Guide
The controller fails to respond and the IRQ LED (and possibly
other LEDs) remains lit.
The IRQ LED indicates that the controller IRQ assignment is
pending. This usually indicates an IRQ conflict with another
card. Verify that each card is set to a unique IRQ. Refer to
Appendix A
for the location of the LEDs on your controller.
The controller does not respond and one of the following LED
patterns occurs during startup:
IRQ 6 and 7 alternating with IRQ 5 and 8
IRQ 5 and 6 alternating with IRQ 7 and 8
IRQ 5 and 7 alternating with IRQ 6 and 8
These patterns indicate that the controller is not being
configured by the motherboard BIOS. This could be because your
motherboard BIOS is not compatible with the Adaptec controller.
This incompatibility could be because it does not support
multifunction devices where one of the devices is a PCI bridge or
because it does not support large, memory-mapped, address
ranges.
Refer to
Chapter 1
file on the Adaptec RAID Installation CD for information about
motherboard compatibility and a list of motherboards that
Adaptec has tested with the Adaptec controller.
The controller fails to respond.
Check the LEDs. They emit patterns that can indicate a variety
of problems, particularly with the memory module. If the LEDs
flash once per second in any of the following patterns, perform
the specified remedy.
