External SCSI Connectors
The external SCSI connectors on the controller are female, Very High
Density Component Interconnect (VHDCI) connectors.
The cables should have the VHDCI offset connector at one end and a
VHDCI or High Density, 68-pin connector at the other end. Such cables with
the correct offset hood and connector assembly are required if cables are to
be connected to external channels 0 and 1 or external channels 2 and 3 at one
time.
