Check Your Network Switch

  1. Check that all Ethernet cables are firmly connected at both the Symphony I/O and network switch ends.
  2. Make sure you're not using an "Energy Efficient Ethernet" (EEE) or "Green" switch. If your switch does include these features, consult the switch documentation to determine if they may be disabled.
