Automated Test Results Documentation to Link-Live Cloud Service

Link–Live allows test results from LinkSprinter, LinkRunner AT, LinkRunner G2, AirCheck G2, and OneTouch AT hand-held network testers to be automatically uploaded providing users with a unified dashboard of both wired and Wi-Fi network connectivity results.

Test results are automatically sent to your secure Link-Live results management dashboard providing organizations with a newfound ability to quickly and easily document the network. This provides organizations with the ability to provide proof of performance and better manage jobs and staff efficiency.

Link-Live provides a single database for test results across media types be it copper/fiber/Wi-Fi:

  • Reduces results management overhead across media types
  • Broadens collaboration perspective and capability
  • Simplifies single report across media types
  • Direct remote control of OneTouch
  • Attach photos to each result
  • Asset tags
  • Serial numbers of installed devices
  • Green light proof AP was working when job was completed

Cable Length, Wiremap and Location

Locate cable runs with toning, switch port advertisement, switch port link light blinking, and remote cable identifiers. Toning supports both analog and digital IntelliTone modes.
Validate patch cord and installed wiring for length, reversed and crossed pairs, as well as distance to fault for opens, shorts, and split pair with integrated Time Domain Reflectomery (TDR).
Easily conduct cable test in three different ways: on a non-terminated cable, with a WireView Cable Identifier, or with the built-in wiremap port on the side of the LinkRunner AT

Cable Location

Cable Location, such as Cable toning, flash port and numbered WireView adapters, is also supported. Perform a patch cable test with the integrated loopback test. Just plug in each end of the RJ-45 into the two RJ-45 ports on LinkRunner G2 to see pin to pin connectivity.

Discover Nearest Switch and VLAN

The LinkRunner G2 uses the IEEE Link Layer Discovery Protocol (LLDP) plus the Cisco and Extreme Discovery Protocols (CDP and EDP) to display the VLAN and nearest switch model, slot, and port.

  • The LinkRunner G2 displays critical nearest switch information including:
  • Switch name and model
  • Switch Chassis, slot and port#
  • Switch IP Address
  • VLAN's supported
  • Duplex and speed (actual and advertised)
  • Signal Strength
  • Connection (MDI or MDI/X)
  • PoE voltage and power (actual and test limit)

Packet Reflector

The LinkRunner G2 packet reflector mode allows it to be used as a remote device during end-to-end network path performance tests to validate LAN and WAN throughput capabilities up to 1Gbps. The reflector mode can be configured to swap MAC and/or IP addresses. LinkRunner G2 supports packet reflection for:

Smart Tester that runs Android APP's

The LinkRunner G2 is the first Smart Tester that includes Smart Phone like features, 5" touch screen with built-in Camera and flash light, and running the Android OS.  Many job related Android apps can be download to the unit, eliminating the need to use a separate personal tablet or smartphone for the task.  With it optional Wi-Fi and Bluetooth, and dedicated copper and fiber Ethernet interfaces, LinkRunner G2 can communicate directly with many end-devices for configuration.  Because the apps that can be pre-loaded onto the LinkRunner G2 can be controlled, it poses less of a security risk than a personal smart phone.  Besides, the typical mobile device has no ability to validate wired Ethernet infrastructure – it cannot test PoE, cabling, link negotiation or network services.

Example of workflow Eefficiency gains: imagine how much time it would save to have a single device that could:

  1. Receive a trouble ticket
  2. View supporting .pdf or other documents that describe the job
  3. Verify PoE and network connectivity via AutoTest
  4. Automatically document test results on unit or to the Link-Live Cloud service
  5. On-board camera to document installed devices, scan QR/barcodes, etc.
  6. Configure any IoT device that supports an Android app or the Chrome browser
    1. Configure an IoT device (security camera, AP, digital lighting controller, HVAC)
    2. Telnet into a switch
    3. Run a Speedtest to the Internet

TruePower™ PoE loaded test for up to 90W 802.3bt Type 4 PSEs

LinkRunner G2 is the first field tester able to validate loaded PoE performance by drawing actual power up to 802.3bt 90-100W across all four pairs. Load the circuit to stress switches, cabling and patch panels, all while measuring the voltage and pairs being used. Using the TruePowerTM test to validate the power delivery before installing IoT connected devices ensures a smooth deployment and helps to alleviate finger pointing.
