Diagnostic Tests
After power on, the hub automatically performs a diagnostic self-test. During
this test, port status LEDs indicate the success or failure of each test.
The system tests each component one at a time. At the completion of the test, if
no diagnostic LEDs are lit, then all components passed the test. If a component
fails the test, the corresponding LED will continue blinking. The following
table identifies the component that corresponds to each diagnostic test LED.
