AR/GE/FE/U 80/80X Installation Manual 3.3 3.0 NO ERRORS Correctable Errors Detected QUAL Voltage (VDC) 2.0 1.7 CORRECTED ERRORS Uncorrectable Errors Detected 0.3 0.0 UNCORRECTED ERRORS 0 0 Errors Deframer Unlocked (Link Down) Figure 3.10.32: Quality Voltage Graph · Quality Voltages between 3.0V and 3.3V indicate PRE and POST FEC errorfree wireless link. · Quality Voltages between 2.0V and 3.0V indicate a low rate of errors that the forward error correction will correct. The lower the voltage, the more errors are being corrected. · Quality Voltages between 0.3V and 1.7V indicate excessive PREFEC errors in the wireless link, some of which cannot be corrected by the FEC. To indicate this change in error performance, the quality voltage will drop from 2.0V to 1.7V in a single step. · Quality Voltages below 0.3V indicate an unlocked deframer condition. This will be recognized as a linkdown condition. 31 58000519 rev. D
AR/GE/FE/U 80/80X Installation Manual 4 Radio Link Status Indicators During normal operation, the following conditions should exist at the radio, as shown in Figure 41: · The Power LED should be lit—solid green; · The 1000BaseX (Fiber) LED should be lit—solid green; · The Radio Link Up LED should be lit—solid green; · The Link Quality BER voltage normally should be 3.03.3v when it is not raining. Figure 41: LED's indicating power, RF link is up and operational, and fiber connected to network equipment The 80GHz system does not require periodic maintenance. However, each end of the link should be periodically inspected for visible damage or excessive accumulation of dirt on the antenna’s radome. 32 58000519 rev. D
