The SCSI device shelves are on one SCSI channel; the hot-swap cages are on another channel. SCSI A may not be connected to a DAC card. SCSI B can be connected to a DAC card.

To change the SCSI addresses, see the “Setting SCSI Addresses” section. For internal cable part numbers, see the “Cabling Diagram Legend.”

The switch settings shown in the example are not the only acceptable settings.
