Replacing Hard Disk Drives
There are two hard drive bays in the server (1 and 2 in Figure 11-3). Each hard drive bay supports a tray-
mounted Ultra-320 SCSI disk drive with single connector attach (SCA) interconnect. The drive tray is
installed into the front of the chassis in the hard drive bay, and then secured in place using the horizontal
handle on the drive tray. A small lever on the front of the server is then rotated into the horizontal position
to connect the SCA connector on the server flex circuit SCSI cable to the SCA connector on the drive. Ultra-
320 SCSI technology (SCA interconnect) or slower hard disk drives can be installed in this hard drive tray.
