Removable-Media Configuration Rules
• Connectors J6 (upper left) and J7 (lower left) of the removable-media storage
compartment require either a storage device (half-height) or SCSI continuity
card. If a half-height device is installed, store the SCSI continuity card in
connectors J4 or J5.
The continuity card architecture in the SCSI section of the system enclosure
is used to minimize the SCSI bus stub length, which is critical to correct
operation.
