Hub Port LEDs
Power and Fault LEDs
When the hub is powered on, it performs its diagnostic self test. The self
test occurs by all port LEDs illuminating and going off. The self-test takes
approximately three seconds to complete.
During the self test:
• Initially, all the hub and port LEDs are on.
• After three seconds, the port LEDs go off.
When the self test completes successfully:
• The large Power LED stays on.
• The large Fault LED goes off.
• The port LEDs go into their normal operational mode.
