## Summary description

Handheld PoE and network cable tester Fluke Networks NetAlly LinkRunner AT 4000 for verifying power over Ethernet and link/transmission parameters. Supports RJ-45, SFP and SFP+ connectors and performs PoE testing and transmission testing. Built-in 3.63 V Li‑Ion battery. Useful for field technicians to validate switch ports, cabling and PoE power delivery.

## Long description

The Fluke Networks NetAlly LinkRunner AT 4000 is a handheld PoE and network cable tester designed for field technicians who need to verify power over Ethernet, link integrity and transmission parameters across copper and fiber interfaces. It supports RJ-45, SFP and SFP+ modules and provides multilayer visibility including Layer 2 and 3 path analysis, switch identification and discovery features. The unit includes a rechargeable Li‑Ion battery and an integrated display for on-site diagnostics and logging via the Link-Live cloud platform.
Advantages
The LinkRunner AT 4000 combines cable validation, PoE measurement and network diagnostics in one portable instrument, enabling faster verification of switch ports and connected devices. Discovery and AutoTest capabilities simplify troubleshooting across multiple VLANs and the device produces topology and test reports through Link-Live for documentation. Built-in path analysis, switch test and packet capture up to 1 Gbps allow technicians to isolate faults and confirm end-to-end connectivity without carrying multiple tools.
Suitable for
Validating switch ports and PoE delivery to IP phones, cameras and wireless access points
Testing copper and fiber links with RJ-45, SFP and SFP+ connections
Field verification of network connectivity, VLAN discovery and path analysis
Quick troubleshooting and documentation of cabling faults, miswires and distance-to-fault measurements
Key specifications
Interface support: RJ-45, SFP and SFP+ for copper and fiber testing
PoE testing: Measures and validates Power over Ethernet delivery and classes
Network tests: Layer 2 and Layer 3 path analysis, switch identification and discovery across VLANs
Performance tools: iPerf3 support and packet capture up to 1 Gbps
Cable diagnostics: Length measurement, common miswire detection and distance-to-fault indication
Connectivity: Ping and TCP port tests to verify reachability
Battery: Built-in rechargeable Lithium‑Ion battery for field operation
Display: Integrated LCD for in-device results and status information
Cloud integration: Link-Live platform for result logging, topology maps and reporting
How to use
Connect the LinkRunner AT 4000 to the port under test using the appropriate RJ-45 cable or an SFP/SFP+ module for fiber links. Run the AutoTest or select specific tests such as PoE measurement, cable diagnostics or switch test from the device menu. Use discovery and path analysis to identify the nearest switch and view Layer 2/3 paths. For deeper analysis, capture packets up to 1 Gbps or run iPerf3 tests to a configured endpoint. Save and upload test results to Link-Live for documentation and further analysis.
Usage recommendations
Use the LinkRunner AT 4000 with up-to-date SFP/SFP+ modules that match the fiber type in use, and ensure the device firmware is current before performing critical validation. Charge the Li‑Ion battery before extended field use and upload results to Link-Live to keep a centralized record of tests and topology maps for future troubleshooting.
