Setting Up the Alert LED

The Alert LED can warn you of potential problems with your network. Quick Config Manager allows you to:

■Test the Alert LED.

■Configure the conditions that cause the Alert LED to light.

■View what conditions have caused the Alert LED to light.

You can configure the Alert LED to light for:

■Incorrect configurations — If there is a network loop due to an incorrect configuration in your network, a port partitions. The coaxial port automatically partitions if it is not used.

■Security Violations — If an unsuccessful login attempt occurs, or a device that is not known to your hub tries to communicate with it, a violation occurs. This may be due to someone trying to gain unauthorized access to your network.

■Poll Failures — If your hub has been configured to monitor a device, it periodically polls it for information. If the device fails to respond, the failure is seen by the hub.

■Network Errors — If the network has high volumes of communication, or there is a high amount of errors with the communication, it could be due to too many devices on your network or an incorrectly configure device.

By default, the Alert LED is configured to light if a 10BASE-T port is partitioned or if there is high network utilization (over 80%).

To configure the Alert LED:

1Do one of the following:

■Double-click on the graphical representation of the hub (but not on a port).

■From the Configure menu, select General Info...

2In the General Info dialog box, choose the Alerts category.

Quick Config Manager displays the Alerts panel, as shown in Figure 4-6.
