BCCs Two Backplane Controller Cards, BCCs, control the disks on one or two buses according to the setting of the Full Bus switch. When the Full Bus switch is set to on, BCC A, in the top slot, accesses the disks in all ten slots. When the Full Bus switch is off, BCC A accesses disks in the even-numbered slots and BCC B accesses disks in the odd-numbered slots. Note In full bus mode, all ten disks can be accessed through either BCC. However, internally each BCC still manages five disks. This means that if the BCC that is not connected to the SCSI channel fails, access to its five disks will be lost. Failure of the BCC that is connected to the SCSI channel will render all ten disks inaccessible.
