C.7 eXtended System Control Facility Unit
The eXtended System Control facility unit (XSCFU or XSCF unit) contains the service
processor that operates and administrates the servers. It diagnoses and starts the
entire system, configures domains, offers dynamic reconfiguration, as well as detects
and notifies various failures.
The XSCF unit uses the eXtended System Control Facility (XSCF) software to provide
the following functions:
■
Controls and monitors the main unit hardware
■
Monitors the Oracle Solaris OS, power-on self-test (POST), and the OpenBoot
PROM
■
Controls and manages the interface for the system administrator (such as a
terminal console)
■
Administers device information
■
Messages various events remotely
■
Interlocks power due to remote cabinet interface (RCI)
Note – To use RCI, a SPARC Enterprise server or a device with an RCI port is
required.
Both midrange servers have one XSCF unit, which is serviced from the rear of the
system. To replace it, you must power off the server
.
Refer to Section 9.1, “XSCF Unit Replacement” on page 9-1 for replacement
