Observing LED Behavior During a Diagnostic Test

Whether you run a diagnostic test on an I/O module or MSM/MM, 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/MM, and switch LEDs, see the hardware documentation listed in

Publications on page 24.

I/O Module LED Behavior

Table 23 describes the NETGEAR 8800 series 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

This section describes the MSM behavior during a diagnostic test.
