Fault monitoring and diagnostics
Fault monitoring, diagnostic tests, and system status indicators simplify switch
management and ensure the availability of the 2109 Model M12.
Diagnostic tests
Diagnostic testing occurs in three areas: power-on self test (POST), switch level
testing, and manufacturing tests.
v
The POST tests are blade oriented and ensure that the switch is ready for use.
Testing is performed on physical ports.
v
Switch level tests are done at the user port level. The tests rely on the standard
Fabric OS support to provide routing and port setup.
v
Manufacturing support includes long duration testing.
System status indicators
LEDs on the noncable side of the switch summarize the system status of each
switch blade assembly, each CP blade assembly, and each power supply module.
The blowers, which are accessible on the noncable side, also have LEDs that
indicate their status.
Cable-side LEDs
Table 4 describes the appearance of the LEDs on the cable side of the system:
