7.2 Indicators for electrical Ethernet ports

The status of the electrical Ethernet ports is indicated with 6 Light Emitting Diodes (LEDs), 3
for each electrical port. The LEDs are located in the upper left corner of the ETH100 board,
so you have to remove the front cover of the sub rack to inspect them.
The LEDs are labelled E1 and E2 for electrical port #1 and electrical port #2.
