Hi
I noticed problem with connection of a computer.
Same connection had worked without a problem before.
DHCP failed due to no connection resulting in windows7 assigning a IP address, no network
When inserting RJ45 the Green link led turned on for a brief moment.
Only got a 100Mbit FD connection after some jugglinng with rj45 in both ends.
In case of oxid building over nigth
The cable is more than 10 meters.
A fluke network tester had problem connecting to ports with a 1 m cable.
This usually means autoneg problem or low voltage.
When I turned off green ethernet/short reach for the switch(sg300-20) and I got a 1000Mbit FD without a problem.
I have previously noted that the voltage on the transmitter from the switch is on the low side using a Fluke network tester.
I got around 0.5 V and I prefer much higher.
I guess turning green features on and trying to use a longer cable is to stretch the luck a tad to much.
