    Operational status : OFF <-- This shows POE is enabled but no power supplied. To flap: “set interface x/x/x disable / enable”. When a problem occurs with PoE, in most cases, the error symptom can be simply shown as the PoE switch not providing power, and the powered devices will stop working. The cause of failure may be attributed to many factors, including hardware device factors and software factors. How to precisely. This guide is for troubleshooting Power over Ethernet (PoE) in the Catalyst 3750-E, 3750, 3560-E, and 3560 switch product families. For precise CLI and message format, see the switch software configuration guides and command references for. The solution for troubleshooting a PoE issue includes trying the steps outlined below before concluding that the issue is due to configuration problems, interoperability issues, or physical defects that require the device to be RMA'ed. This guide provides a step-by-step troubleshooting. The lights on POE switches mainly include power indicator lights, system operation status lights, POE mode status lights, and business interface indicator lights.
