CHAPTER 3 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 LNK/ACT, 1G or 10/100 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 20. The PoE LED is off and/or power is not being supplied to my PoE-enabled device. (For GS1100-8HP) • Check to see that the power adaptor is securely connected to the GS1100-8HP and an appropriate power source. Make sure the power source is on and functioning properly. • Check that the Ethernet cables are connected properly and that you are using the correct type of Ethernet cable. Contact your local distributor if the problem persists. GS1100 Series User's Guide 19
