17. Connect the external SCSI interface cables and power cords supplied with
the internal device bay expansion kit. See Figure 4-84.
The following examples show two different methods of connecting the SCSI
interface cables. See Figure 4-84:
Example 1: Shows the method of connecting two 5.25-inch tape drives
!
to two SCSI controller boards. For this method, connect a SCSI
controller board to a 5.25-inch tape drive with an external SCSI
interface cable (supplied with the internal device bay expansion kit) for
group 1 SCSI cable connectors and group 2 SCSI cable connectors.
Example 2: Shows the method of connecting two 5.25-inch tape drives
!
to one SCSI controller board in daisy chain fashion. When using this
type of connection, you must be careful of the cable length. Check the
total length of the SCSI interface cables to ensure that it is 6 meters or
less (the cable length inside the device bay is 2 meters, the length from
the SCSI board to the device bay is 1.5 meters, and the length between
the device bays is 0.3 meters).
