Status and Activity LEDs

There are two types of LEDs for the network ports: port LEDs and Ethernet link LEDs. The LEDs for the
six physical ports indicate the link state of an ot interface. There are four LEDs in between each port pair
that indicate the link state of the associated et interfaces, see
state of the ot interface; see
