  Michaela BartonAug 17, 2025
  If the Rx level of your Ceragon Antenna is out of range, it typically means the RSL is very low, often below -80 dBm, indicating the link is down. First, ensure the issue isn't due to rain, multipath fading, or a lack of line of sight. Next, check your link settings, including TX power and frequency. Then, verify the antenna alignment. If problems persist, consider replacing the local or remote ODU.

  If Power Input #1 is down on your Ceragon Antenna, it indicates a subrack redundant power feed failure. First, verify that the power input is correctly connected to the -48 VDC supply. Next, check the -48 VDC supply to the subrack. If you're not using a redundant power feed, disable Power Input #1.

  If Power Input #2 is down on your Ceragon Antenna, it suggests a subrack redundant power feed failure. Initiate troubleshooting by confirming that the power input is connected to the -48 VDC supply. Proceed by inspecting the -48 VDC supply to the subrack. If a redundant power feed isn't utilized, consider disabling Power Input #2.

  Marcus AlvarezAug 28, 2025
  If you encounter an open cable error with your Ceragon Antenna, where the IDM-ODU cable is open, start by checking the IF cable and its connectors. Verify that the ODU N-type connector inner pin is not spliced, and if it is, replace the ODU. If the issue persists, try replacing the IDM or the ODU.

What to do if Ceragon FibeAir 1500P Antenna has No Signal from ODU?
- J
  Joshua WallsAug 31, 2025
  If there is no signal from ODU in your Ceragon Antenna, meaning no Rx (140 MHz) signal, begin by inspecting the IF cable and connectors. Then, verify that the ODU N-type connector inner pin is not spliced. If it is, replace the ODU. If the issue continues, replace the IDM or ODU. For 1500HP, check the BMA connector center pin on both the RFU and OCB to ensure it is not spliced.
