Appendix B FRU List B-5
The XSCF units provides the following functions by means of the XSCF firmware:
■ Control and monitoring of the server
■ Monitoring of Oracle Solaris OS, power-on self-test (POST), and OpenBoot PROM
■ Control and management of system administrator interfaces such as the
maintenance terminal
■ Control of device information
■ Remote message output for various events
Because the XSCF unit is mounted on the motherboard unit, it cannot be replaced
singly. For information on how to replace the motherboard unit, see Chapter 6.
B.3 Drive
The M3000 server consists of up to four hard disk drives and one CD-RW/DVD-RW
drive unit.
B.3.1 Hard Disk Drive
TABLE B-5 shows hard disk drive specifications.
An SAS device has two data ports. Because each data port resides in a different SAS
domain, this enables complete failover redundancy. If one path fails, communication
is performed through the other independent path.
For the replacement procedure, see Chapter 9.
