HARDWARE INSTALLATION

Chapter2 Hardware Installation This chapter provides installation procedures are generally outlined as follows:  Verify system configuration  Installing the ODU  Installing the POE  Mounting and alignment the antenna  Connecting external equipment You may need to use Web Browser to change or set the MTIBR5811(E1) system’s operating parameters. Refer to chapter 3, Bridging network attachment and configuration, for more information. 2-1 Unpacking the Equipment The tools required for unpacking the system equipment are:  Utility knife  Clean, flat working surface Open the shipping containers, carefully remove the equipment and place it on a clean, flat working surface. Save the shipping and packing material in case the equipment has to be returned. Check the equipment and installation kits against the packing list to ensure that the equipment part numbers, parts, and ancillary equipment included in the shipment match what is specified on the packing list. Shipments consist of an ODU and an installation kit in one container. Verify the configuration as described in verifying the System Configuration. If there are discrepancies between the packing list and the equipment received, contact your sales representative. Inspect the equipment for any type of shipping damage. If any part of the shipment is damaged, contact your sales representative for repair or replacement instructions. 2-2 Verifying the System Configuration The MTIBR5811(E1) system consists of an Outdoor Unit (ODU), POE and an installation kit.
2-3 Installation Kit Most of the materials needed for installation are supplied with the system. Some tools and equipment must be supplied by the user. Table lists materials in a typical installation kit. Refer to the packing list for a description of the exact contents.

Grounding of all equipment at a radio site is required. Without proper grounding, voltage potentials between components of the system can cause electrical damage when interconnecting cables are installed. It is recommended that the ODU be installed with lightning rod protection. Also, to avoid surge current caused by lightning circulating to the equipment earth system, connect the equipment earth system (true ground) to the lightning rod ground. Please connect the ground node to the existing ground. Note: Ground wires and hardware are not provided in the installation kit. 2-5 ESD Protection ESD (electrostatic discharge) can damage electronic components. Even if components remain functional, ESD can cause latent damage that results in premature failure. Personnel and equipment must be properly grounded. Always wear proper ESD grounding straps during equipment installation, maintenance and repairs. Connect your ESD grounding strap to the ESD connector.

If the null has changed, repeat the procedure until the null is maintained after tightening the fasteners. 9. Disconnect the voltmeter and replace the RSSI protective cap. Note: The signal level over the link is not optimal until both antennas are correctly aligned. 2-10 External Antenna For BR5811(E) If you use the external antenna option, you can follow the antenna installation guide to fixed the antenna and use the RF cable in the installation kit to connect the Bridge and antenna.
