2.3.3 RX7i Embedded Ethernet Interface

Ethernet Ports
The RX7i embedded Ethernet Interface provides two RJ45 Ethernet ports. Either or both of these ports
may be connected to other Ethernet devices. Each port automatically senses the data rate (10 Mbps or
100 Mbps), communication mode (half-duplex or full-duplex), and cabling arrangement (straight-through
or crossover) of the attached link. For Ethernet port pin assignments, refer to Chapter 5. See also
Establishing Initial Ethernet Communications, Section 3.4.1.
For details on Ethernet communications, refer to the following manuals:

Ethernet Interface Indicators
The Ethernet Interface indicators consist of seven light emitting diodes (LEDs). All are single-color green
LEDs controlled by the Ethernet interface.
▪
Ethernet Interface OK (EOK)
▪
LAN online (LAN)
▪
Status (STAT)
▪
Two activity LEDS (LINK)
▪
Two speed LEDS (100)
The EOK, LAN, and STAT LEDs are grouped together and indicate the status of the Ethernet interface.
Each Ethernet port has two green LED indicators, LINK and 100.
•
The LINK LED indicates the network link status and activity. This LED is illuminated when the
link is physically connected and blinks when traffic is detected at the port. Note that traffic at
the port does not necessarily mean that traffic is present at the Ethernet interface, since the
traffic may be going between ports of the switch.
•
The 100 LED indicates the network data speed (10 or 100 Mbps). This LED is illuminated if the
network connection is 100 Mbps.
LED operation is described in the following tables.
GFK-2222AD
& RX3i TCP/IP Ethernet
The two ports on the Ethernet Interface must not be
connected, directly or indirectly to the same device. The hub or
switch connections in an Ethernet network must form a tree;
otherwise duplication of packets may result.
