Chapter 1 XSCF Overview 1-9
ACTIVE LED
The ACTIVE LED lights up in green. If the XSCF Unit is in a redundant
configuration, the ACTIVE LED indicates the active XSCF Unit.
Connector That Connects the XSCF Unit for the Base Cabinet With the
XSCF Unit for the Expansion Cabinet
The connector for connecting between XSCF Units is used to connect the Base
cabinet to an Expansion cabinet on the M9000 server. Field engineers should connect
this connector.
1.2 XSCF Functions
This section describes XSCF functions.
Monitoring the Server Status and RAS Function (Fault Management)
XSCF constantly monitors the server status, so the system can operate with stability.
If XSCF detects a system abnormality, it collects a hardware log immediately and
analyzes it to locate the fault and determine the failure status by using the Fault
Management Architecture (FMA). XSCF displays the status and, if necessary,
degrades the faulty parts, degrades the faulty domains, or resets the system to
prevent another problem from occurring. XSCF thereby maintains high system
reliability, availability, and serviceability (RAS).
XSCF Shell and XSCF Web
XSCF provides the XSCF Shell and XSCF Web that enable the user to display the
server status, operate the system, operate domains, and display the console.
XSCF Unit Diagnosis
When the input power is turned on or the XSCF is reset, XSCF performs initial
diagnostics for the XSCF itself, checks for abnormalities, displays any detected
abnormality, and reports it to the user. While the system is operating, the error
detection facility of the XSCF continues to monitor itself, and if any errors are
detected, it will report them.
