## Summary description

The NetAlly LinkRunner AT 4000 is an advanced PoE tester supporting RJ-45, SFP, and SFP+ connectors. It features built-in lithium-ion battery and complies with EMC and FCC standards. Ideal for network and cable testing.

## Long description

The NetAlly LinkRunner AT 4000 is a professional PoE tester designed for validation and troubleshooting of Ethernet-powered networks. SupportingRJ-45, SFP and SFP+ interfaces, the device verifies power delivery over Ethernet, link integrity and basic network services. The tester includes a built-in rechargeable lithium‑ion battery and meets common EMC and FCC requirements for electromagnetic compatibility and emissions. Its compact form factor is intended for field technicians who need quick verification of link status and PoE availability across copper and fiber connections.
Advantages
The tester supports multiple physical interfaces — RJ-45 for standard copper links and SFP/SFP+ for fiber and high‑speed connections — enabling a single instrument to cover diverse cabling environments. The integrated lithium‑ion battery provides portable operation for on-site diagnostics without dependence on external power. Compliance with EMC and FCC standards ensures the unit operates within regulated emission limits and is suitable for professional network environments. The device is focused on essential PoE testing functions and link verification, streamlining routine network validation tasks.
Suitable for
Field testing of Ethernet copper links with PoE delivery
Verification of fiber links using SFP or SFP+ transceivers
Rapid on-site troubleshooting and link integrity checks
Installation validation during network rollouts or upgrades
Key specifications
Supported interfaces: RJ-45, SFP, SFP+
Power source: built-in rechargeable lithium‑ion battery
Functionality: PoE presence and basic power negotiation checks, link status and basic network service validation
Form factor: handheld, portable tester for field use
Regulatory compliance: conforms to common EMC and FCC emission standards
How to use
Connect the appropriate interface of the LinkRunner AT 4000 to the network port under test — use the RJ-45 port for copper Ethernet or insert a compatible SFP/SFP+ transceiver for fiber or high‑speed links. Power on the tester and allow the unit to complete its self-check sequence. Initiate the PoE or link test function to detect presence of power, observe link speed/duplex indications and verify basic network service reachability as provided by the instrument. After testing, disconnect the unit and recharge the internal battery as needed to maintain readiness for subsequent field use.
Usage recommendations
Use certified SFP/SFP+ transceivers compatible with the tester when checking fiber or multi‑gigabit links. Ensure the internal battery is charged before deployment and follow local guidelines for electromagnetic compatibility when operating near sensitive equipment. For extended diagnostics beyond basic PoE and link verification, combine the tester with full-featured analyzers or protocol testers as required by the task.
