LAN Ethernet port
Front panel 10/100-Mbps Ethernet LAN port labeled
ENET (ETH0)
is presented on a RJ-45 connector with
an auto-sensing/full-duplex 10Base-T or 100Base-T interface. Also included are:
•
100Base-TX half-/full-duplex operation (100 + 100)
•
10Base-T half-/full-duplex operation (10 + 10)
•
Auto negotiation and fallback
•
10/100 Mbps link and status indicators on the RJ-45 connector
•
Two LEDs per port (see
): link/traffic LED (solid green when link is established; flashing green
when the port has traffic) and 10/100 Mbps LED (solid yellow at 100 Mbps; off at 10 Mbps)
