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 fingertips, 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). 2 Dell PowerVault 2xxS Storage Systems SCSI Backplane Board Replacement Instructions
