Differential SCSI
Single host, one master subsystem, and one slave subsystem
This configuration provides a Differential SCSI solution using two dual-bus CR8e
subsystems connected to a single host computer with a standard Differential SCSI
host adapter. From this configuration an array can be created using up to sixteen
(16) disk drives — 8 drives per drive group.
Verify that the jumper at location JP1 on the S2S Interface card is removed.

Connect one end of a 25 meter data cable to the host bus adapter (HBA) and
the other end to the "IN" port on the CR8e master subsystem S2S Interface
card. Secure the cable connectors using the thumb screws.

Connect a one (1) meter data cable from the "OUT" port on the CR8e "Master"
subsystem S2S Interface card to the CR8e "Slave" cabinet "IN" port on the S2S
Interface card. Secure the cable connectors using the thumb screws.
