Explanation

No PoE On Only One Port Follow these steps when the trouble is on only one switch port. Confirm that PoE and Non-PoE devices do not work on this port but work on other ports. Step 1 Verify that the powered device works on other ports and that the problem is only on one Step 2 Use the show run and show interface status privileged EXEC commands to verify that the port is not shut down. (Most Cisco switches turn off port power when the port shuts down.) Step 3 Use the show interface status privileged EXEC command to verify that the switch port is not error disabled. Step 4 Use the show run and show power inline interface-id privileged EXEC command to verify that the power inline never interface configuration command is not configured Step 5 Verify that the Ethernet cable from the phone to the switch port is good. Connect a known good non-PoE Ethernet device to the Ethernet cable, and make sure that it establishes a link and exchanges traffic with another host. Step 6 Verify that the total cable length from the switch front panel to the connected device (powered device) is not more than 100 meters. For more information, see the cable diagnostics section in the switch software configuration guide. Step 7 Disconnect the Ethernet cable from the switch port. Use a short Ethernet cable to connect a known good Ethernet device to this switch port (not at a patch panel). Verify that the device establishes an Ethernet link and exchanges traffic with another host, or ping the port VLAN SVI. Next, connect a powered device to this port, and verify that it powers on. If it does not power on, go to Step 8. Step 8 Use the show inline power and show inline power detail privileged EXEC commands to compare the number of connected powered devices against the switch power budget (available PoE). Verify that switch power budget can power the device. r_over_ethernet.html
