PoE sieťový a káblový tester Fluke Networks NetAlly LinkRunner AT 3000 – RJ-45, SFP/SFP+, Li-Ion 9750 mAh

The Fluke Networks NetAlly LinkRunner AT 3000 is a handheld PoE network and cable tester designed for field verification of Ethernet and fiber links. It verifies link connectivity, link speed and duplex, network services such as DHCP and DNS, switch discovery and PoE delivery. The unit supports both copper RJ‑45 and SFP/SFP+ interfaces and includes a built‑in Li‑Ion battery (9750 mAh / 36.39 Wh) in a compact housing (196 × 102 × 42 mm). The tester is EMC and FCC compliant and integrates with the Link‑Live reporting platform for result storage and analysis.

Advantages

The LinkRunner AT 3000 provides a fast AutoTest that evaluates key network functions and link parameters up to 10 Gbps, detects multigigabit rates (2.5G, 5G, 10G) and performs detailed cable diagnostics for copper and fiber. TruePower™ PoE testing measures real power available under load to confirm up to 90 W delivery. Switch discovery through CDP/LLDP/EDP gives immediate visibility of connected ports and VLAN information. Built‑in battery capacity supports extended field use, and integration with Link‑Live enables easy documentation and sharing of test results.

Suitable for

• Network engineers performing onsite link verification and troubleshooting
• Technicians testing Power over Ethernet installations and PoE-enabled devices
• IT staff validating copper and fiber uplinks, including multigigabit links
• Field teams requiring portable testers with integrated reporting

How to use

Power on the LinkRunner AT 3000 and connect the device to the network via the RJ‑45 port or an SFP/SFP+ module. Run the AutoTest to automatically check link status, speed/duplex, DHCP and DNS reachability, and PoE delivery. For PoE checks, enable TruePower™ mode to apply a controlled load and measure available power at the port. Use cable diagnostic functions to perform wiremap, length measurement and locate faults on copper runs, or to verify fiber link signal and SFP status. Test results can be reviewed on the device display and uploaded to Link‑Live for reporting and analysis.

Recommendations

For reliable field operation, ensure the Li‑Ion battery is fully charged before extended use and use appropriate SFP/SFP+ modules for fiber tests. When testing PoE, connect known loads or PoE devices to validate real‑world power delivery. Keep firmware updated and upload test results to the Link‑Live platform for centralized documentation and trend analysis.
