Q
What is a Ubiquiti PoE injector?
A
A Ubiquiti PoE injector is a network device that delivers both data and power over a single Ethernet cable to compatible PoE-enabled devices, eliminating the need for separate power supplies.
Q
How do Ubiquiti PoE injectors work?
A
Ubiquiti PoE injectors insert DC power onto the spare pairs or data pairs of an Ethernet cable, providing up to 24 watts or more to PoE-enabled devices while maintaining Gigabit data throughput.
Q
Which PoE standards do Ubiquiti injectors support?
A
Most Ubiquiti PoE injectors support Passive 24V, IEEE 802.3af (15.4W), and IEEE 802.3at (30W) standards, ensuring compatibility with a wide range of network devices.
Q
How do I choose the right Ubiquiti PoE injector for my device?
A
Select a Ubiquiti PoE injector based on your device’s power requirement, Ethernet speed (10/100/1000 Mbps), and PoE standard (Passive 24V, 802.3af/at) to ensure reliable operation.
Q
What is the maximum cable length for Ubiquiti PoE injectors?
A
Ubiquiti PoE injectors support Ethernet cable runs up to 100 meters (328 feet) at standard CAT5e or higher, delivering both data and power without significant voltage drop.
Q
Can I use a Ubiquiti PoE injector with non-Ubiquiti devices?
A
Yes, Ubiquiti PoE injectors are compatible with any IEEE 802.3af/at PoE-enabled device and many Passive 24V devices, provided the voltage and wattage requirements match.
Q
How do I install a Ubiquiti PoE injector?
A
Connect your network switch to the injector’s data-in port, attach your PoE device to the data-out port, then plug the injector into AC power; no configuration is required.
Q
What safety features do Ubiquiti PoE injectors include?
A
Ubiquiti PoE injectors feature overvoltage protection, short-circuit protection, and thermal shutdown to protect both the injector and connected devices from damage.
Q
How can I verify a Ubiquiti PoE injector is supplying power?
A
Check the injector’s LED status: a solid green light indicates proper power delivery and data link status to the connected device.
Q
Do Ubiquiti PoE injectors support Gigabit Ethernet?
A
Yes, all current Ubiquiti PoE injectors support Gigabit Ethernet speeds (10/100/1000 Mbps) for high-bandwidth applications such as cameras and access points.
Q
What is the power budget of Ubiquiti PoE injectors?
A
Power budgets vary by model: Passive 24V injectors deliver up to 24 watts, 802.3af injectors up to 15.4 watts, and 802.3at injectors up to 30 watts per port.
Q
Can I use multiple Ubiquiti PoE injectors on one switch?
A
Yes, you can connect multiple Ubiquiti PoE injectors to a non-PoE switch, but each injector requires its own AC power outlet and must not exceed its individual power rating.
Q
What troubleshooting steps should I take if my PoE device won’t power on?
A
Verify injector LEDs, ensure cable quality and length are within specifications, confirm device compatibility with PoE standard, and test with a known working injector.
Q
Are Ubiquiti PoE injectors weather-resistant?
A
Most Ubiquiti PoE injectors are designed for indoor use; for outdoor installations, use a weatherproof enclosure or an outdoor-rated PoE injector.
Q
What warranty coverage do Ubiquiti PoE injectors have?
A
Ubiquiti PoE injectors typically include a one-year limited warranty covering defects in materials and workmanship under normal use.
Q
How can I extend the range beyond 100 meters with Ubiquiti PoE injectors?
A
To exceed 100 meters, deploy Ubiquiti PoE-compatible extenders or powered Ethernet switches at intermediate points to regenerate data and power signals.
