Installation Guidelines

Because the Cisco Wireless Gateway for LoRaWAN is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:

  • Perform a site survey before beginning the installation.

  • Install the device in an area where structures, trees, or hills do not obstruct radio signals to and from the device.

  • The Console-Reset port and the Reset button are under a hex-shaped sealed plug. Inspect the seal of the plug and properly tighten it at the time of installation, and also every time the plug is removed and replaced. Tighten the plug to 15 lbf-in. If you do not tighten the plug properly, it will not meet IP67 criteria, and may lead to water leaking into the unit.

Figure 1. Connecting Console Port and USB Port
  • If the DC power port, LAN port, or the PoE-In port is not in use, the port’s covering plug must be tightened to 12.5 in-lbs (1.41 N-m) torque. Otherwise, it may lead to water leaking into the Cisco Wireless Gateway for LoRaWAN.

Statement 280


  1. Before you install an antenna, contact your Cisco account representative to explain which mounting method to use for the size and type of antenna that you are about to install.

  2. Select your installation site with safety, and performance, in mind. Remember that electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

  3. Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.

  4. Plan your installation carefully and completely before you begin. Each person who is involved in an installation must be assigned to a specific task and know what to do and when to do it. One person must be in charge of the operation to issue instructions and watch for signs of trouble.

  5. When installing your antenna, follow these guidelines:

    • Do not use a metal ladder.

    • Do not work on a wet or windy day.

    • Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.

  6. If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer.

  7. If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company to have it removed safely.

Installing a Lightning Arrestor

Overvoltage transients can be created through lightning static discharges, switch processes, direct contact with power lines, or through earth currents. The Cisco lightning arrestor limits the amplitude and duration of disturbing interference voltages and improves the over voltage resistance of in-line equipment, systems, and components. A lightning arrestor that is installed according to these mounting instructions balances the voltage potential, thus preventing inductive interference to parallel signal lines within the protected system.

Installation Considerations

Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed through on the wall of the protected space.

The importance of obtaining a good ground and bonding connection cannot be overstressed. Consider these points when grounding the lightning arrestor:

  • Connect the lightning arrestor components directly to the grounding point.

  • The contact points of the ground connection must be clean and free of dust and moisture.

  • Tighten threaded contacts to the torque specified by the manufacturer.

Cable for the Lightning Arrestor

Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable must be kept as short as possible because the cable length also determines the amount of signal loss. The longer the run, the greater the loss.

Cisco recommends a high-quality, low-loss cable for use with the lightning arrestor.
