Q
What is an HPE PoE injector?
A
An HPE PoE injector is a compact device that delivers power and data over a single Ethernet cable to PoE-enabled devices without requiring a PoE switch.
Q
How does an HPE PoE injector work?
A
An HPE PoE injector sits between your switch and device, injecting up to 30 W of DC power onto Ethernet pairs while passing network data transparently.
Q
What are the benefits of using HPE PoE injectors?
A
HPE PoE injectors simplify installation, eliminate separate power outlets, centralize power management, and enable remote reboot of VoIP phones, cameras, and access points.
Q
Which HPE PoE injector models are available?
A
HPE offers models such as the 54V 30 W injector (JH330A) and 30 W midspan injector (JH270A), each supporting IEEE 802.3af/at standards and various mounting options.
Q
Are HPE PoE injectors compatible with non-HPE switches?
A
Yes. HPE PoE injectors comply with IEEE 802.3af/at, ensuring compatibility with any switch or device that meets the same PoE standards.
Q
How do I install an HPE PoE injector?
A
Connect the injector’s Data In port to your switch, the Data + Power Out to your PoE device, then plug the injector into AC power and verify the LED status.
Q
Can HPE PoE injectors supply enough power for high-performance cameras?
A
Yes. HPE PoE injectors deliver up to 30 W per port, sufficient for most IP cameras, including PTZ and infrared models, when paired with Cat5e or higher cables.
Q
How do I verify HPE PoE injector output?
A
Check the status LEDs: green indicates valid power and data delivery, amber signals power negotiation, and off means no PoE output or faulty connection.
Q
What cable category is required for HPE PoE injectors?
A
Use Cat5e or higher shielded/unshielded twisted-pair cable to ensure reliable PoE power delivery and Gigabit Ethernet performance.
Q
Can I mix IEEE 802.3af and 802.3at devices on the same HPE injector?
A
Yes. HPE PoE injectors auto-negotiate power levels, supporting both 15 W (802.3af) and 30 W (802.3at) devices simultaneously.
Q
Do HPE PoE injectors support remote reboot?
A
Indirectly. While injectors themselves do not provide management, pairing them with an HPE management switch or controller enables remote cycle power on ports.
Q
What safety certifications do HPE PoE injectors have?
A
HPE PoE injectors carry UL, CE, FCC and RoHS certifications, ensuring compliance with international safety, electromagnetic and environmental standards.
Q
How do I troubleshoot an HPE PoE injector?
A
Verify AC power, cable integrity, and LED indicators. Test with a known-good PoE device and replace cables or injector if LEDs remain off or amber.
Q
Can HPE PoE injectors affect network performance?
A
No. HPE PoE injectors pass Gigabit Ethernet traffic unchanged, so data throughput and latency remain consistent with direct switch connections.
Q
What is the warranty on HPE PoE injectors?
A
HPE PoE injectors come with a one-year limited warranty covering defects in materials and workmanship, extendable through HPE Care Pack services.
