Observing LED Behavior During a Diagnostic Test
Whether you run a diagnostic test on an I/O module, an MSM, or a Summit X450 switch, LED activity
occurs during and immediately following the test. The LED behavior described in this section relates
only to the behavior associated with a diagnostic test. For more detailed information about all of the
I/O module, MSM, and switch LEDs, see the Extreme Networks Consolidated XOS Hardware Installation
Guide.
I/O Module LED Behavior—BlackDiamond 10K Switch
Table 23 describes the BlackDiamond 10K switch I/O module LED behavior during a diagnostic test.
After the I/O module completes the diagnostic test, or the diagnostic test is terminated, the DIAG and
the Status LEDs are reset. During normal operation, the DIAG LED is off and the Status LED blinks
green.
MSM LED Behavior—BlackDiamond 10K Switch
Table 24 describes the BlackDiamond 10K switch MSM LED behavior during a diagnostic test.
After the MSM completes the diagnostic test, or the diagnostic test is terminated, the SYS LED is reset.
During normal operation, the status LED blinks green.
I/O Module LED Behavior—BlackDiamond 8800 Family of Switches
Table 25 describes the BlackDiamond 8800 family of switches I/O module LED behavior during a
diagnostic test.
