10/100Base-TX Ethernet
Connectors
The connectors on La cards adhere to appropriate standards agreed upon by various
standards bodies and are widely available.
This section includes pin usage information for the RJ-45 twisted pair connector.
PCI-X 10/100Base-TX card Twisted-Pair Connector
The same connector on the card is used for either 10Base-T or 100Base-TX operation.
The operating mode is determined by the setting of the hub or switch to which the card is
connected.
Connector Pin Usage for 10- Mbit/s Twisted-Pair Connector
Use unshielded twisted-pair cables that comply with the IEEE 802.3 Type 10Base-T
standard. See Table B-2 for pin information, and Figure B-1 for the pin layout.
