Connectivity (Cables/Devices)



Connectivity (Cables/Devices)

If you attach both internal and external SCSI devices to the host adapter, you must terminate the last external device and the last internal device. (This applies to both the AHA-2940 and AHA-2940W adapters.)

  If you connect external devices to the AHA-2940W adapter, you can only attach devices to one of the internal SCSI connectors.
If you connect both internal and external SCSI devices, you must also change the host adapter termination settings from the default, because the host adapter is now in the middle of the SCSI bus. See 'Termination (AHA-2940/2940W Adapters)'

Component    Requirement
  
Maximum external cable length    3 meters (9.8 ft.)
  
Maximum combined length of all    6 meters (19.7 ft)
cables connected internally
and externally to each adapter
SCSI Devices    Supports single-ended devices only
  
CD-ROM Drive    The CD-ROM drive has a 50-pin connector.
     If it is connected to the 68-pin connector
     on the adapter using a 68-pin to 68-pin
     cable, a 16/8 Bit Converter must be used
     to connect the CD-ROM drive to the 68-pin cable.
  
AHA-2940 and AHA2940W    50-pin to 50-pin SCSI ribbon cable
50-pin internal connector
AHA-2940W 68-pin internal    68-pin to 68-pin SCSI ribbon cable
connector
AHA-2940 50-pin external    50-pin to 50-pin SCSI shielded cable
connector
AHA-2940W 68-pin external    68-pin to 68-pin SCSI shielded cable
