Key Features

Discover Nearest Switch and VLAN

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

The LinkRunner G2 displayes 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 Strenght
  • Connection (MDI or MDI/X)
  • PoE voltage and power (actual and test limit)
  • Graphical representation of power on pairs

True Power PoE loaded Test for up to 90W

LinkRunner G2 is the first field tester able to validate loaded PoE performance by drawing actual power up to 802.3bt 90W across all four pairs. The device loads the circuit to stress switches, cabling and patch panels, all while measuring the voltage and pairs being used. LinkRunner G2 uses the TruePower test to validate the power delivery before installing IoT connected devices to ensure a smooth deployment.

Get Answeres Fast without AutoTest

The LinkRunner G2 Li-ION battery can be charged via PoE and can power up in just seconds from its standby mode. The enhanced AutoTest performs a set of complex connectivity tests in seconds. LinkRunner G2 quickly and accurately validates various network health variables:

  • PoE loaded test up to 90W
  • Link speed and duplex (actual and advertised)
  • RX pair, polarity and signal level
  • 802.1x authentication
  • Discover the nearest switch/slot/port and data/Voice VLAN
  • List all VLANs seen from the switch port
  • DHCP discovery with vendor classification ID and shows Option 60 and Option 150 response, commonly used in VoIP and WiFi deployment and show subnet and DHCP server addresses
  • Gateway and DNS server availability and responsiveness
  • Ping or TCP port connectivity tests to an unlimited number of user-defined targets

Packet Reflector

The LinkRunner G2 features a packet reflector mode that allows the device to be used as a remote endpoint during end-to-end network path performance tests to validate LAN and WAN throughput capabilities up to 1Gbps. LinkRunner G2 supports reflection for: 

  • OptiView XG Network Analysis Tablet
  • OneTouch AT Network Assistant

Comparing to LinkRunner AT

The LinkRunner G2 has 6 key values over that of LinkRunner AT:

  • Complete PoE validation: functionally test voltage, draw power, up to 90W from PSE´s and measure voltage from PoE injectors
  • Verify complex network readiness for WiFi access point and VoIP phone deployment: automatic VLAN visibility in AutoTest and support for DHCP options 43, 60 and 150
  • AutoTest for testing the network at different sizes or stages of completion: versatile "Stop After" setting, unlimited number IP Targets of connectivity test, "Continuous" testing function to verify connectivity consistency to IP Target and large internal and external storage for test results and site data
  • Do more while connected to the switch to reduce trips back and forth to MDF/IDF: detects link speed issues due to cable faults, utilize 90W PoE power, and add pictures or comments to test results directly from LinkRunner G2
  • Run Android apps to consolidate workflows: configure devices, interact with corporate systems or the internet with a web browser and run a functional test
  • Advanced troubleshooting functions: Protocol capture and VLAN monitor

Smart Tester that runs Android Apps

The LinkRunner G2 is the first network tester that features smartphone like qualities, such as a 5" touch screen with built-in camera, flashlight, and running the Android OS. Many job-related Android apps can be downloaded to the unit, eliminating the need to use a separate personal tablet or smartphone for the task. With the optional WiFi and Bluetooth function, 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.

Example of a typical workflow with LinkRunner G2:

  • Receive a trouble ticket
  • View PDFs or other documents that are needed for the job
  • Verify PoE and network connectivity via AutoTest
  • Automatically document test results on unit or to the Link-Live cloud service
  • On-board camera to document installed devices, scan QR/barcodes, etc.
  • Configure any device that supports an Android app or the Chrome browser
    A) Configure an IoT device (security camera, access point, digital lighting controller, HVAC)
    B) Telnet into a switch
    C) Run a speed test to the internet

Programmable AutoTest Profile for IoT Projects

Some IoT systems installations require conducting network services tests at various stages of deployment. The necessary AutoTest Profiles can be created, such that the LinkRunner G2´s will test for the specific configuration needed at each installation stage, providng clear Pass/Fail documentation of the deployment.

Additional information can be appended to the test results, such as images of the location where the device is deployed (using LinkRunner G2´s onboard camera), the serial number of the IoT devices as scanned by a barcode app and technician comments.

Key Service and Device Connectivity

LinkRunner G2 can run ping, TCP port open, or HTTP connection tests. The test conducted will reveal connection and response time to the default Gateway, preferred DNS server and alternate DNS server. The LinkRunner G2 connection test supports unlimited user-defined target devices, servers or services, based on IP address or URL. Continuous testing can be executed on a specific target to verify intermittent behavior, based on response time.

Cable Length, Wiremap and Location

Easily find opens, shorts, miswires and split pairs three different ways:

  • On non-terminated cable
  • With a WireView Cable Identifier
  • With the built-in wiremap port on the side of the LinkRunner AT

LinkRunner G2 has the unique capability to detect and test distance to open even when the cable is connected to a switch

Cable 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.
