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. The user
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 filler 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.
NOTE
Because all hard disk drives have different cooling, power and vibration
characteristics, Intel validates specific hard disk drive types in the
SR870BN4 system. Refer to the SR870BN4 Server System Validation
Summary on the Intel Business Link for a list of these drives available.
