Adaptec 1744 Network Card User Manual


 
LED on host adapter after power-on - The LED on the
AHA-1740A/1742A/1744 should come on briefly after turn-
ing the system power on. The LED should turn off when
a request is sent to the host adapter.
LED on host adapter during operation - If the LED on the
AHA-1740A/1742A/1744 is always on, the orientation of
the SCSI cable between the host adapter and the drive
may be reversed. For the proper orientation refer to the
AHA-1740A/1742A/1744 Installation Guide.
If the LED begins to blink at regular intervals then the
host adapter has detected an internal failure and should
be returned for repair or replacement to the place of pur-
chase. An error message may also appear on the screen.
If the AHA-1740A/1742A/1744 BIOS message does not display on
the screen then the computer system is not recognizing the host
adapter.
Check the AHA-1740A/1742A/1744 BIOS address to
ensure it is not conflicting with other host adapters in-
stalled in the computer system.
Try a different BIOS address. For the proper address
refer to the AHA-1740A/1742A/1744 Installation Guide.
Change the BIOS wait-state jumper. For the proper
jumper settings refer to the AHA-1740A/1742A/1744
Installation Guide.
Try changing the BIOS address from the default of
CC000h to DC000h, or some other available value.
If the following message displays:
host adapter not found at port 330h
Check the port address setting. Verify the correct installation of
the SCSI cable. An inverted or misplaced internal SCSI cable,
generating a forced SCSI reset, may be causing the problem.
