Status LED
The USB 100BASE-T1 MediaConverter has one status LED on the frontside of the case
for the 100BASE-T1 Port.
It is lit when there is linkup. It is toggling when there is communication.
Note
: There is a bug in the used BroadR-Reach PHY. When the 100BASE-T1 Plus and
Minus lines are swapped, and the 100BASE-T1 port is set to Slave, then the Link LED
is lit, but there is no data transmission possible. So please ensure that the 100BASE-
T1 lines (positive/positive and negative/negative) are connected correctly.
