Drive Preparation
1. Remove the drive from its protective packaging.
2. Plastic Drive Bezel - If installing a hard drive which is equipped with a plastic front
bezel, remove the drive bezel.
3. SCSI Drive Termination - The last drive on any SCSI channel must have termination
enabled. In most instances, depending upon the cable configuration, termination will
be handled by an external terminator on the DS500 back panel. If using an external
terminator, disable onboard drive termination. In some RAID configurations, onboard
drive termination is mandatory. Refer to the manufacturer's instructions which
accompany the optional equipment for SCSI termination requirements (refer to section
"Connecting the DS500 to a Computer System" for additional SCSI connection
information).
4. SCSI ID Selection and Device Jumper Configuration - Determine the location that
each device will occupy within the DS500 chassis and label each device accordingly.
Locate the SCSI ID select jumper pins on each drive (refer to the device manufacturer's
documentation if necessary, for the location of the SCSI ID pins). Select a unique ID
for each device connected to a single host, and position the SCSI ID jumpers on the
pins according to the device manufacturer's instructions. Label each drive with the
SCSI ID number to facilitate installation.
Carefully select the appropriate SCSI ID number(s) for the installed device(s).
Selecting the same number on different devices may cause unpredictable results and
the computer system may not recognize the installed device(s). If the computer system
can not recognize the boot disk, the computer system may fail to properly start-up.
The SCSI ID is an address number (0 through 7 for 8-bit protocol and 0 through 15 for
16-bit protocol) that is assigned to each SCSI device. Each device in the chain must
have a unique SCSI ID number. SCSI ID 7 is usually reserved for the host controller.
If the computer system is already equipped with internal or external SCSI storage
devices, some ID numbers will already be reserved. For instance, if the computer
system came with an internal SCSI hard drive, it may be designated as SCSI device
0 (refer to the computer system documentation for additional information). If the drives
are to be attached to a RAID controller, refer to the RAID controller's documentation
for SCSI ID selection information.
5. If installing 3.5" devices into the DS500, attach the 3.5" adapter brackets (included)
to the drives (Figure 7). The adapter brackets can be attached to the drive with four
(4) #6-32 x 1/4" screws.
6. Connect the 4-pin DC power cable(s) to the power connector(s), located on the rear
of the device(s) (Figure 8).
