Full-Bus Cabling and Switch Configuration Cabling for a full bus configuration requires connecting one SCSI cable from the controller to the disk enclosure and setting the configuration switches. Figure 69 illustrates full-bus cabling connections for a six disk enclosure array. It is possible to configure any number of disk enclosures, from one to six, using this method. However, full bus is typically used when four or more disk enclosures are installed in the array. Note For consistency and ease of managment, it is recommended that you observe the following rules: - Connect channel 1 on the controller enclosure to the disk enclosure mounted directly beneath the controller enclosure. Connect channel 2 to the next disk enclosure down, and so on down the rack. - Install cables along the left side of the disk enclosure connectors (as viewed from the back of the rack) and install terminators along the right side connectors. To configure the disk array for full-bus operation: 1. Connect one end of a SCSI cable to the controller enclosure SCSI channel 1 connector, J12 JVD ARRAY SCSI 1. See Figure 69. 2. Connect the other end of the SCSI cable to the disk enclosure BCC A, SCSI connector B. Note The lower BCC is inverted from the upper BCC. Make sure you take this into account when setting the switches. 3. Set the Enclosure (Tray) ID rotary switches on both BCCs to "0". See Figure 68. 4. Set the Enclosure DIP switches on both BCCs to the following settings: a. Set segment 1 to "1" b. Set the remaining four segments to "0". See Figure 68. 5. Connect a terminator to SCSI connector A on BCC A (see Figure 69, "T"). 6. Repeat the preceding steps for each disk enclosure, using the next sequential SCSI channel and incrementing the Disk Enclosure (Tray) ID setting for each enclosure. 188 Attaching SCSI Cables and Configuring the Disk Enclosure Switches
