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.

2-4 Grounding
Proper grounding of equipment and structures is essential to prevent electrical
damage to the MTIBR5811(E1) system.
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.

2-7 Installing the ODU
The MTIBR5811(E1) can be mount on a 2” Steel or Stainless Steel Tube. You can
reference the Figure.

2-8 Connecting the cable
An
Ethernet cable connects the ODU to the POE output port. The cable connects
power to the ODU and allows Ethernet data to flow between Stations with Bridge
system. Another Ethernet cable connects the station to POE input port. A
C power is
applied to the bridge system by connect it to POE AC adapter.
2-9 Align the Antenna (TBD)

Note: The signal level over the link is not optimal until both antennas are
correctly aligned.
