Removable Media Drive Bays
The slim-line LS-240 and DVD/CD-ROM drives and their adapter boards are installed in plastic carriers
(see Figure 6) and are inserted from the front of the removable media drive bay. You must switch off
system power and remove the peripheral bay to remove or install these drives. If the LS-240 is not
included with the server, then a ller panel must be used (see D in Figure 6).

SCSI Backplane Board
The SCSI backplane board mates with the midplane board connector. It contains three 80-pin Single
Connector Attachment (SCA)-2 connectors for hot-swap hard disk drives. The SCSI backplane board
performs the tasks associated with hot-swapping the hard disk drives and enclosure monitoring and
management. The features supported by the SCSI backplane board include the following:
• Monitoring the SCSI bus for enclosure services messages, and acting on them appropriately.
Examples of such messages include: activate a drive fault indicator; power down a drive that
has failed; and report SCSI backplane temperature.
• SAF-TE intelligent agent, which acts as proxy for “dumb” I2C devices (that have no bus
mastering capability) during intrachassis communications.
