PURPOSE Provide instructions on how to properly terminate a network cable PROCESS Gather all materials Network cable Connector - RJ45 Crimping tool Wire cutters/strippers After all materials are gathered and cable has been run to the necessary location we can start terminating the cable ends. Strip the outside wire approximately 1/2 in from the end of the cable. NOTE: Do not cut the colored strands inside as this will prevent the cable from working. Next is to order the smaller internal wires in the proper order. Mister uses the T568B connection order. Orange/White Orange Green/White Blue Blue/White Green Brown/White Brown Next, insert the ordered cables into the connector. Make sure to insert the cables in as far as they can to verify proper connections Now crimp the connector using the crimp tool The cable is now ready for testing and use.

PURPOSE This document explains how to test a store’s internet connection via Netgear LM1200. PROCESS Go to the IT rack and find the Meraki and the Netgear NOTE: Both are usually located on the top shelf Make sure the Netgear is connected to Meraki Firewall on port Internet 2. On the Meraki Firewall find the Cat 5 cable (usually a yellow cable) connected to Port Internet 1. Unplug it. Go to the manager’s PC and open the Command Prompt Search “Command Prompt” in the search bar by the Windows icon. In the Command Prompt window, type “ping 8.8.8.8 -t” and press “Enter”. This will generate “Request timed out” error messages. After getting the error messages, let the command run for about 10 minutes. The Netgear should start up automatically and a message similar to the one below should show. This confirms the backup internet is operational and a solid white LED light should be on the front of the Meraki Firewall Go back to the computer rack and plug the Cat 5 cable back into the Port Internet 1 on the Meraki Firewall. (Yellow Cable) Return to the manager’s PC and make sure you are still getting a reply in the command prompt. If you are, perform a Google search to confirm the store has internet (e.g., Google “Mister Car Wash”). If the reply in the command prompt still shows “Request timed out”, make sure the Cat 5 cable is plugged into the Port Internet 1 on the Meraki Firewall. If this doesn’t fix the issue, contact Mister IT. Close the Command Prompt app.

PURPOSE Instruction guide for mounting the Meraki Cellular Gateway at a store. PROCESS What is the Meraki Cellular Gateway? It is NOT a WAP (Wireless Access Point); it will not provide any Wi-Fi coverage for phones or tablets. This is a cellular modem. This provides a backup internet connection. If primary internet isn’t installed, it is the lifeline for the store. Why does it need to be placed on the roof? Mainly to provide the best signal strength and quality. For best performance it needs a clear line of sight to the cell tower. This means the roof is the best location. Early attempts to place lower and less conspicuous placement locations have only resulted in internet speed issues. Before IT ARRIVES What needs to be up on the roof? 2 Network Cables 1 White shielded cat5e 1 Grey shielded cat5e How do we want it up there? Using the conduit in the tower, run it up through there and out the tower and to one of the 2 weatherheads. The other end will join all the other network cables in the IT closet. How much cable needs to be up on the roof? As much as needed to reach the optimal weatherhead locations. Which weatherhead does it need to run to? You can contact IT to help pre-determine which weatherhead has the best line of sight to the nearest cell tower. Weatherhead locations Red Lines = Network Cables After I.T. arrives An IT Technician will set up and install the SIM card in the gateway. After setup, the device will need to be mounted. Mounting Rules: No closer than 3’ from a section of metal siding or roof. The device will need to be above the side walls of the roof. MOUNTED Example (to show how high up the gateway needs to be above the roofline.)
