Troubleshooting X330W-2USP
You can obtain statistical information regarding module performance, error rates, and DTE/DCE signal statuses using the show interfaces command.
•Cable connection fault - When there is a fault with the cable connections or when a DCE cable is connected. Check the cables and connections.
•Host communication fault - When the X330WAN can not establish a connection with the host P330 switch. In this case, verify that the appropriate software versions are installed in the host P330 switch.
If X330WAN (or the connected DCE) reports data errors (CRC, etc.), there might exist a phase shift between the data and the accompanying clock. In this case use the invert txclock command to invert the transmit clock signal (TxC) from the DCE.
