NETSCOUT’s Next-Gen LinkRunner Tester Is Ready For The Changing Network Landscape

Just when you thought that maybe all of the cool testing innovation was reserved for Wi-Fi and the likes of the AirCheck G2, NETSCOUT brings out an equally impressive wired networking tester. The new LinkRunner G2  (shown on left below) sports the same color scheme and physical profile as the AirCheck G2:

But a closer look topside reveals some tell-tale features:

What isn’t obvious from these images is that NETSCOUT made the LinkRunner G2 with a whole new user-customizable philosophy in mind that applies to both hardware and software. See the fiber SFP on the left and the USB WLAN adapter on the right side in the second image? You don’t HAVE TO get those from NETSCOUT if you find a better price on similar interfaces elsewhere. Unlike some vendors, NETSCOUT opted to be very accommodating of 3rd party adapters. And the LinkRunner G2 is actually a hardened Android computing platform that you can tweak in a number of ways- but let’s come back to that in a bit.

Recognizing the LAN-Scape For What It’s Becoming

In talking with LinkRunner’s product management, I was able to hear the inside scoop on where the company sees the product fitting into the connected world. It’s no secret that the number and type of network-connected devices “out there” is skyrocketing, but investment in support staff and their capabilities isn’t for many organizations. That being said, the LinkRunner G2 is viewed by NETSCOUT as the “smart network tester for the connected world”. Now, I’m as buzzphrase-adverse as anyone, but the deeper you dig into the LRG2, the more you realize that NETSCOUT is not over-hyping the new tester’s capabilities. With strong physical layer support capabilities, LRG2 is handy before the network even goes live. On active networks, Ethenet and core services are tested and characterized nicely. Then there are the true differentiators- and Power over Ethernet (PoE) functionality is a prime example.

Robust PoE Measurement and Charging

NETSCOUT points out that today’s LAN environment is no longer just a client-access domain, it’s also a power-distribution system for a growing number of devices. Beyond VoIP phones, CCTV cameras and wireless access points, we now have lighting systems, locks, and Bluetooth sensors among the many devices using PoE for operating power.

Netscout describes the LRG2 as the only current tester fully able to support all versions of PoE including Universal PoE (UPOE) that sources 60 watts at the switchport and up to 51 watts at the field jack. And this LinkSprinter also charges off of PoE!

Link-Live

Depending what other NETSCOUT (or Fluke Networks) tools you use, you may already be a Link-Live user.

 

Link-Live makes the storing, sharing, and reporting of test results and absolute cakewalk. When you have a number of staff with varying skillsets, NETSCOUT’s Link-Live-capable tools can bring a uniformity of testing that reduces errors and faulty troubleshooting, and makes the results available for reference and escalation. It’s a free service, and LinkSprinter G2’s tests are as well formatted as the likes of the AirCheck G2’s. I’m a fan.

The Multi-Function Tester That You Can Customize

This tester is still a LinkSprinter, so you’d expect to see views like this on the crystal-clear touchscreen as you test copper and fiber links:

 

But there is sooooo much more. Remember, I said that this is a full-blown Android device. It also happens to have many “phone-like” features including a built-in flashlight, camera (attach pictures to Link-Live reports or email them from the LRG2), web browser, screen shot capabilities, Micro SD slot for file storage and portability, and even access to other apps that can be installed on the tester.

This is so handy, and almost too good to be true. The caveat to the starting app paradigm? You don’t have access to the full Play Store. This is a hardened Android device after all, and you do not log in to the Play Store with your own account. But you do have access to a wide range of vetted network/documentation/productivity apps via NETSCOUT’s partnership with Google. If you find an app that you’d like, NETSCOUT provides an easy path to request it.

Within five minutes after discovering this capability, I had my test unit nicely loaded with some of the same Wi-Fi and network apps I use on my own Android phone and tablets, and the ability to run them all off of a robust network tester feels incredibly empowering.

There is just a lot here to appreciate in the LinkRunner G2. It’s clear that NETSCOUT was shooting for versatility and expandibility with this network tester, and they hit both targets nicely.
