Appendix A provides information on the pin specifications for the connectors.
The CPU module is the main source for signal distribution in a BA42B
Enclosure system. The SCSI and DSSI cables are connected to the CPU
module. Each of the other connectors on the cables has a pull-tab. Use the
pull-tab to disconnect the cable from a device. Each pull-tab has a number that
identifies the drive to which the SCSI or DSSI cable connector is connected
(see Figure 1–6).
