■Controls and manages the interface for the system administrator (such as a
terminal console)
■Administrators device information
■Controls remote messaging of various events
Both midrange servers have one XSCFU, which is serviced from the rear of the
server.To replace it, you must power off the server. For moreinformation, refer to the
SPARCEnterprise M4000/M5000 Servers Service Manual.
The XSCF firmware provides the system controland monitoring interfaces listed
below.
■Serial port through which the command-line interface (XSCF Shell) can be used
■TwoLAN ports:
■XSCF Shell
■XSCF Web(browser-based user interface)
The following additional interfaces for system control are also provided:
■The uninterruptible power supply unit (UPC) interface ports (2), which are used
to communicate to uninterruptible power supply units (UPS).
A UPS unit is used to provide a stable supply of power to the system in the event
of a power failureor an extensive power interruption. By connecting the UPC port
of the server and a UPS which has a UPC interface via signal cables, you can
execute emergency shutdown processing when the commercial AC power supply
failure detected.
■RCI port, which is used for power supply synchronization through a connected
remote cabinet interface (RCI) device.
■USB interface port for maintenance operator
This is dedicated for use by field engineers and cannot be connected to
general-purpose USB devices.
