Functional Description B-3
B
There are few differences between board slots and each slot can accept any
board type. However, slot 1 connects directly to the internal SCSI tray through
the centerplane and related cables. The internal tape and/or CD-ROM or other
optional internal SCSI drives cannot be used unless an I/O board is present in
slot 1.
Although the remaining slots are equivalent, I/O boards should be located on
the back side of the centerplane for easy access to interface cables at the rear of
the cabinet.
