Introducing LinkSprinter

Common Use Cases

  • Network Drop Verification

    Network Drop Verification

    1. A trouble ticket comes into the help desk that a user is complaining that they can’t login.

    2. Front-line support receives the trouble ticket, grabs the LinkSprinter and heads to the users desk. Once there, just unplug the network cable from the back of the users PC and plug it into LinkSprinter. In less than 10 seconds, they’ll know if the problem is in the network or the PC.

      All lights are green, problem is in the PC!

      If there is a network problem, the integrated color coded LED will indicate where in the connection path the failure occurred.

    3. In this case, we can see that the issue is that the DHCP server is not serving up an IP address.

      Since there is no network connection, LinkSprinter will hold this bad result in memory.

      Once LinkSprinter is plugged into a good connection, the bad result is automatically uploaded into Link-Live and received in the technicians e-mail, which they can then forward for escalation showing problem domain and any additional information such as trouble ticket number or wall jack location or other important details.

    4. When network engineering can receive escalations with actionable visibility, they are able to solve problems faster and it improves the overall collaboration between teams.

  • Verify Power over Ethernet (PoE)

    Verify Power over Ethernet (PoE)

    1. Your team is getting ready to install several new Wireless AP’s and security cameras.

      You need to ensure good network connectivity at every wall jack and that PoE has been provision properly where each powered device will be deployed. The front line support team is called in to do the pre-deployment validation including documentation of each wall jack and its associated switch slot/port/VLAN.

    2. Plug LinkSprinter into the RJ-45 jack and the autotest automatically begins. In less than 10 seconds you can verify network connectivity is good and the PoE voltage level at the wall jack.

      LinkSprinter can run off the PoE power on the network, so for a long project, you can rest assured you will have no down time with battery charging or replacement issues.

    3. At the completion of each test, you can enter wall jack information either on your mobile phone or through the automated e-mail. Either way, that information appends to the test results providing wall jack to switch slot/port/VLAN path documentation.

  • Validate 1000 Mbps/1 Gigabit Links

    Validate 1000 Mbps/1 Gigabit Links

    1. You are getting complaints from users that the network is slow, yet you recently upgraded to 1000 BASE-T / 1 Gigabit links to improve performance.

      You want to do some spot checking to ensure you are getting the performance you were expecting as the first step in troubleshooting the issue.

    2. Set LinkSprinter to test for 1 Gig links through the mobile UI or Link-Live. Once that’s done, plug in and see the results within seconds.

    3. You can see immediately via the Yellow LEDs on the front of LinkSprinter that there is a warning for your Link speed/duplex. Upon a closer looking on the mobile UI, which is also giving you a warning indication, you see that you are actually getting only 100 Mbps!

      You know that 1 Gig requires four pair termination, so that’s the next step to troubleshoot the problem. With the LinkSprinter, you do a quick check on the cable to verify it was correctly wired.

    4. You found the issue! Looks like this cable was only punched down for two pairs not four. Punch down the open pairs and retest to confirm you found and resolved the problem!

  • Document Test Results

    Document Test Results

    1. As part of a moves adds and changes project across multiple buildings, you would like to document the following and provided a printed report:
      » Network connectivity test results
      » Wall jack to switch slot/port/VLAN path
      »Serial number of connected devices at each wall jack

    2. You’re armed with LinkSprinter and Link-Live Cloud Service and confident you can get this job done quickly.

      Step one is to think about how you want the data organized and you decide to organize results by building so you create folders within Link-Live for each of the three buildings.

    3. You’re ready to begin at building 1, so you set the “sticky comment” in LinkSprinter to the folder name you created for building 1. This will ensure that as results are automatically uploaded into Link-Live, they are filed into the building 1 folder, saving you time when you’re ready to print the results, everything is already filed and filtered for you.

      This also makes it easy should you need to troubleshoot in the future to compare what the connection path looked like when things were working.

    4. During this project, you opt to use the automated e-mail reply feature so you can attach photos rather than the mobile UI.

      At the completion of each test, you receive an email where you reply with the wall jack number and snap and attach a photo of each device. That information gets automatically appended to your test result providing all your documentation requirements.

    5. At the end of the project when you’re ready to provided printed reports, you simply just open each building, select print, and include photos.

Product Details

  • Front

    • Internal Wi-Fi server

      Tap the power button to enable the internal Wi-Fi server. This low power Wi-Fi access point will not allow others to connect to the device and access the internet. Simply connect your smart phone to the “LinkSprinter” SSID and point your internet browser to to see detailed results on your phone.

    • Power Button

      Tap the Power button to turn the LinkSprinter on. Tap again to enable the internal Wi-Fi. Hold 1 to 2 seconds to turn the unit off. The LinkSprinter runs off PoE or 2 AA batteries.
