4. Insert the canister with the drive back into the chassis and close the latch to secure it in
place.
5. Repeat steps 1-4 for each drive you are installing. The disk array will automatically detect
which slots are populated once it is powered on.
2.2.2 Terminating the Host Bus
All SCSI buses must be terminated at each end. Termination absorbs electrical signals and
prevents those signals from bouncing back along the bus and causing interference. If you are
not chaining other devices onto the disk array, be sure to connect the terminators included with
the unit to the open SCSI ports.
2.2.3 Computer Connection
The freeStor Xpand 1500C requires an available SCSI port on your computer. If a SCSI host
bus adapter is required for your computer, it must be installed prior to connecting the computer
to the disk array. For optimal performance, the SCSI port should support a 64-bit Ultra320 SCSI
interface. Once the port has been installed, connect the included SCSI cable from the disk
array to the SCSI port on the computer.
2.2.4 Connecting the Power Cord
Before connecting the power cords to the power supplies, make sure the power supplies are
connected firmly to the chassis. To prevent data loss or corruption during a power outage, it is
advised that you connect the disk array to an external uninterruptible power supply (UPS).
2.2.5 Host Bus SCSI ID Assignment
Before using the disk array, you should assign a SCSI ID to the device. The range of SCSI IDs
on a Wide SCSI bus is from 0 to 15. You can do this by using the web interface or a serial
connection (see the next section for details). Be sure to assign an ID that does not conflict with
any other devices on the host bus or the host adapter.
