Remove the SCSI Hard-Disk Drives
CAUTION: Note the location of the SCSI hard-disk drives as you
remove them from the drive bays. During the installation procedure
(found later in this document), you must return the SCSI hard-disk
drives to the same drive bays from which they were removed.
To remove the SCSI hard-disk drives from the drive bays, perform the following
steps.
NOTE: The storage system comes with either a silver, swing-out lock bar or a
black, removable lock bar, which secures the hard-disk drives in their drive bay
slots.
1. Using the key, unlock the keylock.
2. For a storage system with the silver, swing-out lock bar, using your finger-
tips, tap up on the lock bar. The lock bar easily swings out and down, just
below the level of the drive bays (see Figure 1).
