Link Configuration
The four Ethernet links are configured the following way:
• The first two MAC interfaces are always configured as SMII (Serial Media Independent
Interface). The media interfaces are always configured in the 10/100-TX mode
• The third and fourth MAC interfaces are always configured as RGMII (Reduced Gigabit Media
Independent Interface). The media interfaces are configured in the 10/100/1000 Base T mode of
operation when connected to a copper connector and in the 1000-SX mode when connected to a
fiber connector. The types of connectors used on the I/O spacer is determined by the type of I/O
spacer.
Status LEDs for first EMAC (EMAC0)
Three led pins are physically connected to LEDs. The LEDs are labeled Duplex, Link and 10/100.
Table 3-1 shows their status values.
Status LEDs for EMAC1, EMAC2 and EMAC3
The LED signal lines for any second or third 10/100 TX port are routed to the I/O spacer (MDC).
There are two LEDs above each RJ45 connector. Figure 3-2 shows a I/O spacer with the maximum
of three RJ45 connectors. This number is dependent on model purchased.

See “Front Panel Connectors” on page 21 for more information on the front panel connectors and
configuration options. Table 3-2 and Table 3-3 show the LED status values.
