Section 3 Engineering Guidelines TRACER 4106/4206 System Manual26 © 2004 ADTRAN, Inc. 612804206L2-1A1. EQUIPMENT DIMENSIONSThe TRACER 4106/4206 unit is 17.12” W, 9.34” D, and 1.72” H and can be used in 19 or 23-inch rack-mountconfigurations.2. POWER REQUIREMENTSThe TRACER 4106/4206 system has a maximum power consumption of 20 Watts and a maximum current draw of0.95 Amp (at 21 VDC).3. REVIEWING THE FRONT PANEL DESIGNThe front panel contains an RSSI test point, a GND reference for use with the RSSI test point, and status LEDs toprovide visual information about the TRACER 4106/4206 system. Figure 1 identifies the various test points and theLEDs on a TRACER 4206 front panel. The TRACER 4106 front panel layout is identical to the TRACER 4206front panel.Figure 1. TRACER 4206 Front Panel LayoutRSSI Monitoring InterfaceThe RSSI voltage is a function of the signal strength at the receiver and is used to measure the received signalstrength. RSSI varies from approximately 0 to 5 Volts DC (VDC). An RSSI Calibration sheet is shipped with thesystem to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI voltage.This sheet is useful for verifying link budget calculations and ensuring proper equipment installation.Front Panel LEDsWith the TRACER 4106/4206 powered-on, the front panel LEDs provide visual information about the status of theTRACER 4106/4206 system. Table 1 provides a brief description of the front panel features, and Table 2 providesdetailed information about the LEDs.Table 1.
