## Questions & Answers

**Q: Is there any danger of using these to check ports in a power-over-ethernet (poe) switch?**
A: Only if you have done some crazy hardware alterations or a homicidal arch nemesis.

**Q: Will this work for 10Gbase-T connections over cat6a?**

**Q: Will this test if the eithernet port on my camera is working?**
A: It will be able to test Ethernet connection if your device  has a network card that transmit the signal.

**Q: Does this work on non-gigabit connections as well?**
A: Yes, this adapter is backwards compatible with non-gigabit connections.
