The EMS local GUI is a web-based application supported by standard web-browsers. Microsoft Internet Explorer® is recommended. System configuration and monitoring can also be performed from a remote EMS Server. The EMS Server is a multi-user platform that includes enhanced management capabilities for configuration, monitoring and alarming. The EMS Server is required to generate SNMP alarms. Note:It may take up to 3 minutes for the mBSC system to initialize, therefore it is recommended to only attempt to login to the GUI after the mBSC system has completely started, otherwise the GUI may incorrectly display a message indicating that the username and/or password are wrong (when in fact they may be correct). 5.1.1 Using Ethernet Port Access to the EMS Local GUI through an RJ-45 Ethernet connection is provided on the RCU card in the Host Unit shelf. The Ethernet port is the primary point of connection for the remote EMS Server. The EMS Local GUI accessed through the Ethernet port is assigned the IP address 172.18.60.60 at the factory. However, this IP address can be modified to suit the networking requirements of the installation (e.g. to allow access across a Local Area Network). Steps: 1. Obtain a CAT5 cable and connect it to the RJ45 port on the host unit RCU card, and connect the other end into the RJ45 port on the laptop/computer. Depending on the model year of your computer, a crossover cable may be required. 2. Start an Internet Explorer browser session on the laptop/computer, and enter the following URL to connect to the Local GUI–“http://172.18.60.60”. Note: The mBSC system does not provide DHCP service. To access the GUI you will need to configure the local computer with a static IP address the same subnet as the local GUI. Note: The EMS Local GUI is a single-user interface, and supports only a single user at a time. If the Ethernet interface is connected to a Local Area Network, and more than one user is accessing the EMS Local GUI at the same time, inconsistent operation may occur. Please use the EMS Server for multi-user applications.](https://usermanual.wiki/BTI-Wireless/MBSC0700040RU.Revised-users-manual-same-as-1-10-14/User-Guide-2183431-Page-52.png)

For more information about support for SNMP please refer to UM-MBSC-C-EMS. 5.4 System Tuning 5.4.1 BTS Signal Conditioning The interface from the operator BTS equipment to the MBSC0700-040-RU is via simplex RF connections to the BIU. The nominal downlink input to the BIU (TXin) is 0 dBm±1dB (range: -10dBm to +10dBm). If the BTS signal downlink exceeds +10 dBm, or the signal is a composite duplex RF signal, then RF signal conditioning will be required. BTI provides a high-power Point of Interface to perform RF signal conditioning (mBSC-C-POI) The use and operation of this component is outside the scope of this document. 5.4.2 Set Downlink Gain It may be necessary to adjust the Downlink gain of the mBSC-C system in order to achieve a balanced forward and reverse link, or to adjust for other conditions (input levels from the BTS, propagation characteristics at different bands, specific RF design). The MBSC0700-040-RU provides two points of adjustment for downlink gain: 1. Software controlled attenuator for each band in the BIU 2.

By injecting an RF CW signal at each TXin port of the BIU the end-to-end downlink system gain can be verified without additional test equipment required at the Remote Node. Verify the end-to-end Downlink Gain for each frequency band as follows: 1. Using an RF Signal generator inject a CW RF signal to the TXin port of the BIU a. Set the frequency to the center of the spectrum to be used in the system (if the operator licensed bands are not known set the frequency to center of the band – e.g. 2132.5 MHz for AWS band) b. Set the input RF power level to be 3 – 5 dB below the expected RF level to product maximum output power at the RU to avoid accidental overdrive (e.g. if the gain is set so that 0dBm input will produce +43 dBm at the output then start with -5dBm) 2. The resultant Downlink output power of the RU can be observed in two ways: a. In the topology window the Downlink Output power is displayed next to the specific RU (e.g. 30.7 dBm indicated in the topology diagram by the 800MHz RU in Figure 52 – Up/Down Link Verification) b. Downlink Output Power: In the component window 3. Variations in filtering, amplifiers, and optical loss may cause the actual system gain to vary +/- 6 dB. All paths can be normalized by adjusting downlink attenuation settings in the BIU. 4.

Breaking the seals on equipment under warranty will void the warranty. Do not return equipment for warranty or repair until proper shipping instructions are received from the factory. 6.1 Electrostatic Discharge Precautions The mBSC-C system modules contain assemblies and components which are sensitive to electrostatic discharge (ESD). Carefully observe the precautions and recommended procedures to verify that system reliability is not compromised due to component damage from static electricity. The following precautions will significantly reduce the risk of system failure or malfunction due to ESD: 1. Always wear a grounded wrist strap while working around the system 2. Consider all assemblies, components and connections to be ESD sensitive 3. When unpacking circuit boards, interfaces and modules that are packaged separately from the system, keep them in their conductive wrapping until they are ready to be installed. 4. Before removing or replacing any components, select a work area where potential static sources are minimized 5. Handle circuit packs and boards by the grounded housings, avoiding contact with the connectors 6.2 Preventative Maintenance The mBSC-C system requires minimal regular maintenance to ensure continuous and satisfactory operation. Maintenance includes diagnosing and correcting the service problems as they occur. When an alarm is reported, it is necessary to follow a troubleshooting procedure to identify the source of the problem. The following are recommended routine maintenance procedures: Check the indicator status LEDs (normal or alarm). Prevent dust or grime from accumulating on the surface of heat sinks. Check power output. 6.3 Fault Detection and Alarm Reporting The mBSC-C on-board embedded firmware detects unit and system faults and reports them as system alarms. The following methods may be used to report alarms: Dry-contact alarm points Status LEDs on system components NMS (Local GUI, remote NMS, and SNMP Alarms)](https://usermanual.wiki/BTI-Wireless/MBSC0700040RU.Revised-users-manual-same-as-1-10-14/User-Guide-2183431-Page-76.png)
