Note:
ECC-protected cache is available only when using ECC
memory modules. The ECC-enabled LED on the controller is
lit when ECC memory is installed.
LED Indicators
All Adaptec controllers provide nine LEDs that let you visually
monitor controller activity. Two additional LEDs (ECC EN and ECC
ERR) indicate the status of the cache memory on the controller. For
additional information about LEDs on SCSI RAID controllers, see the
Installation Guide
for your controller.
Power Up LED Status
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 while the controller waits for the host computer to
initialize the Address Translation Unit (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.
