Why do I Repeatedly Receive Error -56?

This error is caused by a TCP timeout during attempts to communicate with the ATCA-3671 over Ethernet.

Note The default IP for ATCA hardware is a private network address (192.168.0.75) that can be reconfigured through SSH per the IT policies of the end user. The ATCA should be cabled directly to a dedicated NIC on a host PC or PXI controller for initial setup.

To avoid this error, complete the following steps:

  • Verify that you have specified the correct IP address for the ATCA SOM.
  • Verify that the ATCA-3671 and the host PC are properly connected with an Ethernet cable.
  • Verify the Ethernet port configuration of the host PC is correct. A unique private network address on the same subnet is required for initial setup.
  • Attempt to ping the ATCA default IP from a command prompt on your host machine.
  • If you are unable to connect to the ATCA-3671, contact your IT administrator for general Ethernet troubleshooting assistance or NI support for ATCA-specific assistance.
