What does the %OC_USD-SLOT18-2-RF_CRC: OC2 received packets with CRC error from MOD 6 through XBAR slot 5/inst 1 error message mean?

These errors indicate that the octopus engine received frames that failed the CRC error checks. This can be caused by multiple reasons. Por exemplo:

• Hardware problems:
  • Bad links
  • Backplane issues
  • Sync losses
  • Seating problems
• Software problems:
  • Old fpga
  • Frames forwarded to LC that it is unable to understand
