Ethernet Port LEDs
Each Gigabit Ethernet port has two built-in
corresponding LEDs. The top LED indi-
cates 10/100 Mbps link and activity status
for the port while the bottom LED indicates
1 Gigabit link and activity status for the
port. The appropriate LED displays green
when a valid Ethernet cable connection
exists. Flashes green as data is transmitted
or received on the port.
Ethernet Ports
The OS7-GNI-C12 module provides 12 10/100/
1000 Ethernet ports. These ports are twisted-pair
and are individually configurable as 10BaseT,
100BaseTX, or 1000BaseT. The ports use RJ-45
connectors.
