Note that once you have connected cables to the hub, 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. The AUI port stays on if it is enabled.
When the self test completes successfully, the LEDs go into their normal operational states. If a hub hardware fault exists, the hub will not complete self test. This will be indicated by an abnormal LED pattern.
If the self test time elapses and the Fault LED continues to stay on instead of turning off, the hub may have an error condition. If repeating the self test does not correct the problem and the Fault LED still stays continu- ously on, contact your reseller for replacement information. After the hub has passed its self test, you are ready to mount the hub.
