File Name: fusion_r400q_no_drives_ug.pdf Document Version: UG-FUS-R4Q-0TB-E-G-041210 File Size: 1.5 MB User's guide for the Sonnet Fusion R400Q 4-bay Serial ATA rack mount drive enclosure with quad interface. These directions apply to storage systems without drives.
The Fusion D400Q and R400Q must have a hard drive in drive bay 1 when connected via USB, FireWire, or FireWire 800. This requirement is due to the Oxford bridge chip that controls USB and FireWire connectons. Drive bay 1 is the top bay in the Fusion D400Q and the left bay in the Fusion R400Q. As long as there is a drive in drive bay 1, bays 2-4 are unconstrained.
Note: This requirement does not apply to a direct SATA connection, which has no drive bay population requirements.
