2.2 1x2 Cabling

The 1x2 can be configured with the controller module either on top of or below the

two disk arrays. Both configurations are described in this section.

2.2.1 SCSI Cabling

2.2.1.1 Cable Lengths

The following table shows the lengths of each SCSI cable connected to the drive

connections on the controller module.

The inboard IN/OUT connectors on each disk array are terminated with a

differential SCSI terminator,part number 150-1890-xx.
