PoE Tester NetAlly LinkRunner AT 3000 RJ-45 SFP SFP+
The NetAlly LinkRunner AT 3000 RJ-45 SFP SFP+ is a compact PoE tester designed for network technicians who need portable, multi-interface verification of power over Ethernet and link connectivity. The unit supports RJ-45, SFP, and SFP+ connections, enabling testing of copper and fiber endpoints and delivering diagnostics for link status and PoE presence. A built-in Lithium‑Ion battery provides field mobility while the tester meets applicable EMC and FCC requirements for safe electronic operation. Its small footprint—102 mm wide, 42 mm deep and 196 mm high—makes it suitable for carrying in a tool bag or pocket for site visits.
The tester combines RJ-45, SFP and SFP+ interface support in a single handheld device, removing the need for multiple testers. Integrated PoE detection and measurement simplify verification of powered devices and power sourcing equipment. A rechargeable Lithium‑Ion battery reduces dependence on disposable cells and supports continuous on-site use. Compliance with EMC and FCC standards ensures the device operates within regulated electromagnetic limits, reducing the risk of interference in professional environments.
Connect the LinkRunner AT 3000 to the network endpoint using the appropriate interface—RJ-45 for copper or an SFP/SFP+ transceiver for fiber. Power the unit using the internal Lithium‑Ion battery and follow on-screen prompts to initiate link and PoE tests. The device will detect link status, negotiate speed and duplex where applicable, and indicate the presence and class of PoE. Use the tester to confirm power sourcing equipment output and to isolate cable or endpoint issues before performing repairs or replacements.
For reliable measurements, ensure SFP/SFP+ transceivers are compatible with the tested fiber type and that connectors are clean before insertion. Recharge the internal battery between extended field sessions and store the tester in a dry, temperature-controlled environment to preserve battery life and device accuracy.
