4.6.2. Carrier/Off-Module Terminations
The following Carrier terminations are required, if the relevant interface is
used. If unused, the
SMARC
Module pins may be left un-connected.

rail
The open drain
GBE status
signals,
GBE_LINK100#,
GBE_LINK1000#
and
GBE_LINK_ACT#,
if used, need
Carrier based
current limiting
resistors and
LEDs. The LED
may be integrated
into a Carrier
RJ45 jack. A
resistor of 68
ohms, and a LED
with the anode
tied to Carrier
3.3V, is typical.
