2.1.3 Connecting the DAS-208SA
DAS-208SA can be connected to the host computer via 2 Ultra320 SCSI ports.
2.1.4 Host Bus SCSI ID Assignment
You may assign any SCSI ID to the host channel. The range of SCSI IDs on a
Wide SCSI bus starts from 0 to 15. You can use the LCD panel or a terminal to
set the host channel ID. (Refer to
Section 3.1 Configuration Methods
for more
information.) Be sure to assign an ID that does not conflict with any other
devices on the host bus as well as the host adapter.
2.1.5 Host Bus Termination
The disk array is shipped with host channel buses terminated. If the disk array
is not the last device on the host bus, you must turn off termination from the
LCD panel or a terminal.
2.1.6 Back Plane
The back plane of the DAS-208SA is specifically designed to furnish the
stability of voltage and provide the reliability for disk array.
2.1.7 Connecting the Power Cord
Before you connect the power cords to the power supplies, make sure the
power supplies have been firmly seated inside the DAS-208SA Disk Array.
2.1.8 Uninterruptible Power Supplies
To insure the integrity of the data stored on a RAID array, we strongly
recommend connecting the DAS-208SA Disk Array to an external UPS.
