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
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
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.
LED Pattern
7, 6, 5, 2, 1
7, 6, 5, 3, 1
