What to do if I am unable to communicate with Symmetricom Power Supply system?
- J
  John RiveraAug 17, 2025
  If you're having trouble communicating with the system, start by checking that all cabling is securely fastened. Then, verify that the communication device is properly configured. If you're still facing issues, try re-seating the Comms module and pressing the RST button on its front panel. Also, ensure that your software emulator's COM port setting matches the physical cable connection (either COM1 or COM2) and that the baud rate is set to 19,200. Lastly, try connecting to another serial port.

How to troubleshoot Symmetricom SSU-2000e with no LEDs lit on any module?
- D
  Dawn BeasleyAug 20, 2025
  If no LEDs are lit on any module, it indicates a power issue. First, check that the UPS, if used, is working correctly. Then, inspect the A and B fuses and replace them if they are blown. Ensure the ground wires are securely attached and that the power cables are firmly connected to the unit. If these steps don't resolve the issue, it might indicate a faulty main shelf.
