Issue Details

PXIe-8523 is supported 1000 Mb/s (1000BASE-T1) but when configure as 1000Mb/s, IPv4 addresses shown 0.0.0.0 and the Link Speed remain Link Down. However, there is no issue when configure as 100Mb/s.

Solution

As there is no issue when configure 100Mb/s, this issue most likely due to the use of untwisted pair cable. 

For Gigabit Ethernet (1000Mb/s), twisted pair cable is required.
