Screen-Based Reference Host DisplaysElement Management System (EMS) 4.0 User Manual714.4.2 Host RF WindowThe host RF (Radio Frequency) window, shown in Figure 62, displays two alarm indicators for the forward path RF composite signal. The window shows operating mode, also, because a mode other than normal may cause the indicators to report falsely. Table 12 describes the RF alarms. Figure 62. Host RF Window Table 12: Host RF Alarms When FaultedALARM NAME DESCRIPTIONOper Mode The operating mode is not “Norml.” (“StandBy” mode will cause a green RF Underdrive indicator to falsely read as red; a red RF Overdrive indicator will falsely read as green. “Test” mode will have no effect on the RF indicators. If mode is “PrgLd,” wait for the load to complete.) For more information on operating mode, refer to Topic 4.1.4, Tools Menu, on page 60.RF Overdrive The forward path composite signal level of all channels from the server is too high. The overdrive threshold is −3 dBFSrms. See also Oper Mode above.RF Underdrive The forward path composite signal level of all channels from the server is too low. The overdrive threshold is −25 dBFSrms. See also Oper Mode above.
Host Displays Section 7Element Management System (EMS) 4.0 User Manual724.4.3 Host WindowThe Host window identifies the bandwidth that the host is set to and contains two subsets of alarms, one for the host unit optics functions and one for the host unit synthesizer functions. The names for these alarms refer in a number of places to “primary” and “secondary” fibers and “forward” and “reverse” paths. For clarification (see Figure 63):NOTE: The “host unit” in the Digivance SDR system is the Host PCIx Card within the BTS server shown in Figure 63.Figure 63. Forward and Reverse Paths(in Product Model With Secondary Fiber)• The host unit (Host PCIx Card) will usually have two primary fibers (connected to host Port 1 and Port 2). These fibers carry the primary forward path (Port 1) and primary reverse path (Port 2) optical signals. If Wave Division Multiplexers (WDMs) are used, both signals may be transported on one fiber between multiplexers on either end. A free space optics link may also be used.REMOTE UNIT19487-AFORWARD PATHPRIMARYREVERSE PATHFIBER OPTICLINKSECONDARYREVERSE PATH(OPTIONAL)LINUXSERVERAPISBSCNETWORK
Screen-Based Reference Host DisplaysElement Management System (EMS) 4.0 User Manual73• Depending on the product model, the host unit (Host PCIx Card) may, in addition, have a secondary fiber (connected to host Port 3) to provide a diversity gain option. In this case, the secondary fiber will carry a secondary reverse path from a secondary antenna.Synthesizer alarms also refer to the primary forward path, primary reverse path, and secondary reverse path because the host unit has a separate synthesizer for each of these paths. The synthesizers are monitored independently; an error condition in one synthesizer will not affect the others. Figure 64 shows the Host window. Table 13 describes the optics alarms when failed. Table 14 describes the synthesizer alarms and band alarm when failed. Table 16 describes the band indicator.Figure 64.

Remote Displays Section 7Element Management System (EMS) 4.0 User Manual804.5 Remote DisplaysThe EMS “remote displays” include seven windows with information available for any operational remote unit currently known to EMS.4.5.1 Remote Alarms WindowThe remote Alarms window reports all major and minor alarm indicators for the remote unit. The indicators are refreshed about once every three seconds. In general, GREEN indicates okay, RED indicates that a major alarm exists, and YELLOW indicates that a minor alarm exists. A major alarm causes RF functions to be halted; a minor alarm allows RF functions to proceed as normal. Figure 71 shows the remote Alarms window. Table 21 describes the major alarms when faulted. Table 22 describes the minor alarms when faulted.Figure 71.

In addition, this window has dashboard displays for RF and Voltage Standing Wave Ratio (VSWR) readings received from the LPA. NOTE: When the LPA has been automatically disabled due to an internal LPA alarm, it may be manually restored. For instructions, position the mouse cursor on the LPA Disable indicator and read the instructions in the pop-up window that appears as shown in Figure 73. In this situation, the remote Alarms window will also display a message indicating to “Reset PA,” as shown in Figure 74.Hardware Mismatch Host unit and remote unit are on different bands.Host Lost Remote unit cannot communicate with host unit.EMS Link Status EMS has not heard from the remote unit for the number of minutes specified by the current value of the EMS Link Timeout parameter (see Topic Topic 3.6, Setting EMS Link Timeout, Cataloging Time, Demo Mode, on page 34).Table 22: Remote Minor Alarms When FaultedALARM NAME DESCRIPTIONTemperature STM temperature is too hot.
