Using the Tester to troubleshoot PoE related issues
- After connecting a PD to the PSE, the PD does not power up and the PSE’s PoE port LED is not on.
1. Check and make sure the PD is compatible with the PSE and the PSE is powered up.
2. Check the network cables are at least Cat 5, in good working order, less than 100 meters long, and
connected to the ports properly.
3. When applicable, check PSE’s settings and make sure the PoE port is enabled.
4. Use the tester to verify that the PSE’s PoE port status and if it is compatible with the PD.
5. If the above are all verified and in good working condition, then the PD could be defective.
