Installing and Removing Drives
17
Setting the Drive Sled Board Jumpers
Depending on the SCSIBox 2 type, the drive sled board jumpers should be
set for either single-ended or differential operation. See Figure 3-1 for the
jumper configurations.
Installing the Drives
Follow these directions to install the drive and drive sled assembly in the
drive box. The drive and drive sled assembly are one modular unit.
Caution: There are two types of SCSIBox 2s and two types of drives,
single-ended and differential. If you do know which type of SCSIBox 2 or
drive type you have, do not install drives into the drive box. Contact your
field support or sales office, as required, to help determine your SCSIBox 2
or drive type.
1. Orient the front-loading drive relative to the SCSIBox so that the drive
is facing toward the right. See Figure 3-2.
2. Carefully insert the device into the drive bay until it seats firmly into
the lever catch and the locking lever has moved all the way down.
3. After you have installed all of the drives, you can power on the drive
box and rack. See Figure 3-2 if you do not know where the power
switch is located.
Caution: Be sure to recheck the SCSI ID of the drives to make sure you do
not duplicate numbers.
