3.2.1.3 Verifying the Ethernet Connection
Once you have connected the unit to an Ethernet outlet, verify that the Ethernet
Integrity Indicator, which is the yellow LED embedded in the DATA port
connector, is on. This indicates that the unit is connected to an Ethernet
segment. The Ethernet Activity Indicator, which is the green embedded LED,
should blink whenever the unit receives or transmits traffic on the DATA port.
