Differential SCSI
Single host and one subsystem
This configuration provides a Differential SCSI solution using a single dual-bus
CR8e subsystem connected to a single host computer with a standard Differential
SCSI host adapter. From this configuration an array can be created using up to
eight (8) disk drives. Additional CR8e's can be added to this configuration by
referring to the Duplex (Dual-Active) schemes under Differential SCSI mode.

(Terminate card remove jumper at JP1)
Verify that the jumper at location JP1 on the S2S Interface card is removed.
This will terminate the SCSI bus.
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 subsystem S2S Interface card.
Secure the cable connectors using the thumb screws.
Turn on the power to the CR8e. After the power-on self-test has successfully
completed, the Status and Channel Mode LEDs will be solid green.
Set the SCSI IDs. The IDs are configured via the Operator Control Panel
using a predefined set. Access the Options menu and select "SAFTE CHAIN
ID" then choose "None."
After setting the subsystem identification you must power cycle the
subsystem. Observe normal power cycling precautions by waiting a minimum
of five (5) seconds before applying power again.
Proceed with completing the installation by configuring the array, refer to
Chapter 3 – Configuration.
