Applications
Flexible Configuration - This hub is not only designed to provide network access

for 10Mbps connections, but also to provide a wide range of options in setting up

network connections. It can be used as a simple stand-alone hub or stacked up to

10 high; or can be cascaded to any compatible hub or switch. A sample

configuration diagram is shown in the following figure.

Troubleshooting
Diagnosing Hub Indicators

The hub can be easily monitored through panel indicators to assist the network

manager in identifying problems. This section describes common problems you

may encounter and possible solutions.

Symptom: Power indicator does not light up (green) after power on.
Cause: Defective power outlet, power cord, or internal power supply.
Solution: Check the power outlet by plugging in another device that is functioning
properly. Check the power cord with another device. If these measures fail
to resolve the problem, have the unit's power supply replaced by a qualified
Accton distributor.
Symptom: Link indicator does not light up (green) after making a connection.
Cause: Network interface (e.g., a network adapter card on the attached device),
network cable, or hub port is defective.
Solution: Verify that the hub and attached device are powered on. Be sure the cable is
plugged into both the hub and attached device. Check the adapter on the
attached device and cable connections for possible defects. See if your
cable is functioning properly by using it for another port and attached device
that displays valid indications when connected to the network. Replace the
defective adapter or cable if necessary. Also verify that you have not
exceeded specified limits for any attached media as summarized in the
following table:
