Power and Cooling Problems

If the Power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fan on back of the unit is unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact your Accton distributor for assistance.

Cabling and Adapters

If the Link indicator fails to light when you connect a device to the hub, check the following items:

•Be sure the twisted-pair cable is properly attached to the connected device and the hub. Verify that the media connector snaps into place when attached.

•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.

•Check the length of each twisted-pair cable to be sure it does not exceed 100 meters (328 feet). If you have cascaded two Fast Ethernet hubs together, be sure the interhub cabling is no longer than 5 meters (16 feet).

•Verify that the workstation's adapter card is functioning properly by trying it in another computer that has been successfully connected to the network.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
