Table 2–1: Port States and Indicators (Continued)
The status indicator displays on the port in the Hardware View. It indicates that a corrective action
is required to return the port to a normal operating state.
Link Incident Alerts
A link incident is a problem detected on a fiber optic link, like the loss of light, invalid
sequences, and other problems. When a problem occurs, a LIN alert is sent to the Link
Incident Log in the switch Product Manager. LIN alerts warn you that there is a link
incident being detected through a port connection that may require operator
intervention to correct.
If LIN alerts are enabled for a port in the Configure Ports dialog box, a yellow triangle
(attention indicator) displays by the port connector in the Hardware View or in the
Alert column in the Port List View. A corresponding triangle displays for the card on
the Hardware View. Double-clicking the port with the yellow triangle displays the
Port Properties dialog box.
If LIN alerts have been enabled for a port in the Configure Ports dialog box, the Port
Properties dialog box contains a short description of the latest incident in the Link
Incident field. Or, if there are no active incidents, "None" displays. The system writes
all link incidents to the Link Incident Log.
If you enable LIN alerts for a port in the Configure Ports dialog box, configure e-mail
notification through the HAFM, and enable E-Mail Notification through the
Maintenance menu, you will receive e-mail notification of LIN alerts.
