10/100 Fast Ethernet Signals on the WMIC
There is one set of fixed 10/100 Fast Ethernet signals on the WMIC. The 10/100 Fast Ethernet port
signals are in compliance with IEEE 802.3. They are provided through the Ethernet headers, which
support the following:
• Auto-negotiation for 10/100BASE-TX connection
• Full-duplex and half-duplex modes
• Low-power sleep mode
• 10BASE-T and 100BASE-TX using a single Ethernet connection
• Robust baseline wander correction performance
• Standard carrier signal multiple access collision detect (CSMA/CD) or full-duplex operation
• Integrated LED drivers
Figure 4-2 shows the 10-pin 10/100 Fast Ethernet header pin locations.
Figure 4-2 WMIC Ethernet Header Pin Locations
Table 4-1 describes the pin assignments shown in Figure 4-2.
Note If Auto-MDIX is disabled, when connecting to Ethernet switches or repeaters a straight-through cable
can be used. When connecting to compatible workstations, servers, and routers, a crossover cable should
be used. If Auto-MDIX is enabled, either a straight-through or crossover cable can be used can be used
to make the connection, as the router automatically changes the signals on the pins to compensate.
