1000SX lan interfaces over cross-over fiber cable ?

[Q4you]

Thanks for your replies.

Here are all the facts :

2 1000SX lan interface cards were connected with standard SC to SC Fiber cable. The rx and tx on a standard fiber cables did not require special configuration. This was done due to very high file xfer requirement between 2 servers ( did not want to load primary IP lan)

The IP configuration is like any other ethernet lan configuration. The max xfer rate over this point to point was appx in the range of 30MB/sec to 80MB/sec.
