Troubleshooting
This section describes common problems you may encounter with the Switch and
possible solutions.
Troubleshoot the Switch using the LEDs to detect problems.
The PWR LED on the front panel does not light up.
• Check the connections from your Switch to the power source. Make sure you
are using the supplied power cord and that you are using an appropriate power
source. Refer to the product specifications.
• Make sure the power source is turned on and that the Switch is receiving
sufficient power.
• If these steps fail to correct the problem, contact your local distributor for
assistance.
The LINK/ACT LED does not light up when a device is connected.
• Verify that the attached device(s) is turned on and properly connected to your
Switch.
• Make sure the network adapters are working on the attached devices.
• Verify that proper network cable type is used and its length does not exceed 100
meters. For more information on network cable types, see Section 3.1 on page
