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.
ODU Configuration
You can refer the photo here for installation.
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. AC power is
applied to the bridge system by connect it to POE AC adapter.
2-9 Align the Antenna (TBD)
Notices
The RSSI BNC connector is still not function well now. Please
use the RSSI reading from the statistics window in WEB -base
browser.
Antenna alignment is performed with both the near-end and the far-end
terminals operating. The antenna position is adjusted while monitoring the RSSI
for antenna alignment voltage. The higher the RSSI voltage reading is, the
stronger the signal. The range of the RSSI voltage reading is from 0 to 3.28VDC,
and the resolution is 256 divisions.
Caution: To ensure optimum system performance, the main lobe of the antenna must be aligned
with the center of the far end antenna. Rotate the antenna through the range of radiated power
so the main lobe can be positively identified. Each side lobe is approximately 20 dB lower than
the preceding lobe as you move away from the main lobe.
This antenna alignment procedure is applicable to both protected and
non-protected system configurations. Align the antenna as follows:
Note: Repeat this procedure if the initial alignment does not produce the correct
RSSI reading.
1. Consult your path calculation and adjust the radio’s attenuation level, so do
not exceed the maximum receiving signal level.
2. Verify that the Bridge at the far end is operational.
3. At the near-end Bridge, remove the protective cap from the RSSI BNC
connector.
4. Connect a voltmeter to the RSSI connector and set the voltmeter to
measure VDC.
5. Pivot the antenna slowly in the azimuth direction. Monitor the voltmeter and
locate the position where the voltage is minimum (null) and record the
reading.
6. Monitor the voltmeter and pivot the antenna in the elevation direction. Pivot
the antenna to the position where the voltage is minimum on the voltmeter
and record the reading.
7. Repeat these steps as necessary to get an accurate reading.
8. Tighten all fasteners and check that the null has not changed. 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.
