mBSC081921-12 System Operation Manual Issue 2 The Network Management System (NMS) is a software-based network management tool that provides control and monitoring function for Bravo Tech Inc. mBSC system. NMS is used to provision and configure new system for operation, set the system operating parameters, get system alarms and status messages and upgrade the system software. 3.1 Software Installation NMS software CD-ROM will be provided to the customer with product package.
mBSC081921-12 System Operation Manual Issue 2 Figure 3-3. Network Management System Main Window 3. Open the Config drop down menu and select Config Port. Or click the Config Port icon menu. Configure the server IP address and port. This IP address should be same with the server IP address and port. The New window will open for setting IP address as shown in Figure 3-4. Figure 3-4. Configuration of IP Address 4.
mBSC081921-12 System Operation Manual Issue 2 menu. The new window for the system configuration will open as shown in Figure 3-5. Figure 3-5. System Configruation Window 5. Define the District for highest level of system configuration as shown in Figure 3-6. User can define each section without rules. After typing the information, click the Add button right-bottom of the window.
mBSC081921-12 System Operation Manual Issue 2 Figure 3-7. Reult window after Defining District 6. After configuring the District, the equipment should be defined. Check the Equipment title and new information sections will be appeared as shown in Figure 3-8. Host Unit should be defined first before adding Remote unit. Check the MU title and type the information for Host Unit. After filling the information, click the Add button. Figure 3-9 shows the result for adding Host Unit in the system configuration.
mBSC081921-12 System Operation Manual Issue 2 Caution: When the system was shipped out, the IP address was pre-defined with default. The customer should changed HU IP address with user defined one. • Note: the IP address of Host Unit is pre-defined when the product is shipped to the customer. The customer can change the default IP address of HU to user defined IP address. Figure 3-9. Result Window after adding HU 7.
mBSC081921-12 System Operation Manual Issue 2 There is the rule to define the Equipment Code for Remote Unit. Warning: Equipment Code for RU should be followed the numbering rule for normal operation. The conflicted Cdoe may casue for the failure of configuration of the system. • The code will be defined with the combination of Slot ID and Port number for FIU module in Host Unit as shown in Table 3-1. Maximum 6 FIU modules can be installed in one HU.
mBSC081921-12 System Operation Manual Issue 2 3.3 Read and Edit the current system setting parameters The User can check the current setting values for the system parameter and edit or modify the parameters for Host Units and Remote Units. The Figure 3-12 and 3-13 shows how to read the current setting parameters and edit the parameters for Host Unit. Remote unit has the same procedure to read and modify the parameters Figure 3-12. Read the current setting for teh system Figure 3-13.
mBSC081921-12 System Operation Manual Issue 2 3.4 Read and Modify the System Gain Budget The User can read the current setting value for the system gain budget of downlink and uplink. The parameters can be read for each HU and RU. Also the User can modify the gain budget for downlink and uplink for whole HU and RU system or for individual Host Unit and Remote Unit. The Figure 3-14 shows the current parameter setting for the system gain budget and the procedure of modifying the parameter. Figure 3-14.
mBSC081921-12 System Operation Manual Issue 2 3.5 Check Alarm Status for the system The User can check the current alarm status for Host Unit and Remote Unit with NMS. The Figure 3-15 shows how to read the current alarm status. Also the User can make enable or disable for each alarms for required purpose as shown Figure in 3-16. Figure 3-15. Read the current Alarm Status Figure 3-16. Change the Alarm Setting © 2009, Bravo Tech Inc.
mBSC081921-12 System Operation Manual Issue 2 3.6 Check the Major performance for the system The User can check the current status of the HU and RU for major items that is related with main system performance like downlink output power, temperature of unit and so on. The Figure 3-17 shows the main performance of the system in one window. Figure 3-17. Check the system performance © 2009, Bravo Tech Inc.
mBSC081921-12 System Operation Manual Issue 2 4 ANTENNA MOUNT ENVIRONMENT The effective radiated power (ERP) limits and power & antenna height limits are related with the distance between operating area and international borders, average distance to the service area boundary, population densities, emission bandwidth, base stations location, different operation frequency band. The antenna for this system is provided and assembled by customer.
