• Local-Remote Mode
Local-Remote Mode loops data received on the Extension Port Rx through the User side
PHY to the Extension Port Tx. Data is not sent out the remote User Port Tx and
incoming data on the remote User Port Rx is ignored. See Figure 21. To set this mode,
set the Loopback State for the Local Module to Remote.

• Remote-Local Mode
Remote-Local Mode loops data received on the User Port Rx through the FPGA to the
User Port Tx. Data is not sent out the remote Extension Port Tx and incoming data on
the remote Extension Port Rx is ignored. See Figure 22. To set this mode, set the
Loopback State for the Remote module to Local.

• Remote-Remote Mode
Remote-Remote Mode loops data received on the Extension Port Rx through the Local
User PHY to the Extension Port Tx. Data is not sent out the local User Port Tx and
incoming data on the local User Port Rx is ignored. See Figure 23. To set this mode,
set the Loopback State for the Remote module to Remote.

For loopbacks, the 9145 uses a unique MAC address, the Loop Test MAC Address, which is
displayed on the Loopback Setup Screen. For details about using the software and
