ADTRAN 4106 Plan A Equipment Dimensions, Power Requirements, Reviewing the Front Panel Design

Section 3 Engineering Guidelines TRACER 4106/4206 System Manual

1.EQUIPMENT DIMENSIONS

The 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-mount configurations.

2.POWER REQUIREMENTS

The TRACER 4106/4206 system has a maximum power consumption of 20 Watts and a maximum current draw of 0.95 Amp (at 21 VDC).

3.REVIEWING THE FRONT PANEL DESIGN

The front panel contains an RSSI test point, a GND reference for use with the RSSI test point, and status LEDs to provide visual information about the TRACER 4106/4206 system. Figure 1 identifies the various test points and the LEDs on a TRACER 4206 front panel. The TRACER 4106 front panel layout is identical to the TRACER 4206 front panel.

RSSI Monitoring Interface

The RSSI voltage is a function of the signal strength at the receiver and is used to measure the received signal strength. RSSI varies from approximately 0 to 5 Volts DC (VDC). An RSSI Calibration sheet is shipped with the system 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 LEDs

With the TRACER 4106/4206 powered-on, the front panel LEDs provide visual information about the status of the TRACER 4106/4206 system. Table 1 provides a brief description of the front panel features, and Table 2 provides detailed information about the LEDs.
