2. Check the LEDs on the hub’s front panel.

When the hub is powered on, it performs a self-diagnostic test.

During the test, all of the hub LEDs are lit for approximately 3

seconds.

When the self-test completes successfully, the following events occur:

• the Power LED stays on

• the twisted-pair Port LEDs enter their normal operating state

• If an HP Transceiver module is installed, the AUI/Xcvr LED will

display the state of that port

A Port LED stays on if link beat has been detected at the port. A Port

LED turns off if link beat is not detected. If you have an optional HP

AdvanceStack 8U/16U SNMP Module installed, the Port LEDs have

additional meanings. See the documentation accompanying the

module for more information. If all of the Port LEDs stay on after 3

seconds and you have not connected end nodes to these ports, the

hub has failed its self-test. See chapter 2, “Troubleshooting” for

information about diagnosing your hub.

3. After the hub has passed its self-test, you are ready to mount the hub.

Before mounting the hub, unplug it.
