2 Product Description As shown in Figure 2-1, MRU is a compact platform with the natural heat convection. As unified form factor, MRU services multiple technologies on a single platform with 4 band operating frequencies. It can be mounted on the wall. Variety of the service antenna can be used from small form factor antenna to indoor multi-band ceiling Omni antenna (or panel antenna).
2.1 External interface ports and Status Indicators MRU has main interface connections at topside of the enclosure, which includes optic, antennas and dc power input. The status LEDs and USB port for maintenance are located on left side. Figure 2-2 shows the top and bottom side of MRU.
2.2 Block Diagram Figure 2-3 shows block diagram of the MRU which supports Quad-band Cellular carriers.

If anything is missing, please contact Intelibs.
3.3 Unit Mounting MRU should be installed vertically such as wall mounting because of heat dissipation. If MRU want to be installed on the rack horizontally, proper cooling devices like fan are required. The following diagrams illustrate the methods for mounting MRU in a typical wall. The brackets for wall mount are provided with MRU system. Figure 3-1 Wall mounting 3.4 Antenna MRU uses various antennas depends on its application and environment.
3.5 Power cable MRU uses +48V DC power by DIN-F passive injector. For DC power source, AC/DC converter with DIN-F connector can be used. Connect DIN connector power cable to the “DC” port. AC/DC Adaptor Figure 3-3 Power cable connection 3.6 Optic cable MRU provides one optic port for upward direction, “Optic” port, and optic connector type is LC/UPC .
Figure 3-5 and 3-6 shows various optic connection of RHU-FHU-MRU equipment.
4 Configuration and Maintenance SRU can be configured in three ways via remote internet connection or local serial port connection. • • • Local management interface through the internet or serial connection Web interface through the internet SNMP interface through the internet Master Unit is a remote management system that provides SNMP and Web interface, and maintains all functions of optical DAS system including configurations, monitoring, and real time alarm reporting.
Configuration guide below shows how to configure and manage MRU system. Figure 2-15 is an example DAS network for the configuration. Figure 4-2 RHU/FHU/MRU network 4.1 GUI connection The on-site local connection between LMT and RHU system can be established via USB interface.
[Laptop connection to MRU] Figure 4-3 USB connection If the USB connection has been established, LMT is ready to start. Click the short cut icon on your laptop and follows the steps below. Step 1 • Run the IDAS GUI.
o Serial Port: The port number established via USB Step 3 • • Connection is established you can see MLU, FHU and MRU connection diagram Select the “MLU” on the above window. Step 4 • • If you want to add the unit to manage, please right click of mouse and you can see the subscreen below. You can open the installation screen as below when you select “Add” button. • For setting ‘Install Remote’, Input proper type and ID in “New Install Device” part.
- Install : Add the Unit under Uplink Device Step 5 • Check the installed device as below browser Step 6 • Double click “MRU” from above browser, then MRU status screen is opened as below. If connection is established successfully, then all parameters of MRU can be set on the GUI, and all status information can be displayed on the GUI. MRU’s status and parameters that can be controlled by GUI are described in Table 4-1, 4-2, and 4-3.

Step 2 • Enter desired TMPUPR value by entering number and enter. Then press “Yes” button when this “AID Request” screen is displayed. The small color box on the left side of “TMPUPR” represents current status of upper limit of MRU chassis’ temperature. If the box is GREEN, operating status is in normal condition. If the box is RED, “TMPUPR” alarm occurred and remains.

6 Human RF Exposure – Maximum Permissible Exposure Evaluation The recent FCC developed guideline for evaluation of the human exposure to the RF emissions. The maximum permission Exposure (MPE) for power density of the transmitter operating RF ranges between 300 KHz and 100 GHz. As the Intelibs RHU belongs to the fixed equipment, Analysis has been conducted to evaluate the MPE from the distance greater than 20 Cm as the fixed equipment required. Antenna gain is restricted to 1.5W ERP (2.
