Appendix B. Ethernet Connector, Cable Specifications<br />
The system board contains an Ethernet controller. The controller has an external<br />
RJ-45 connector on the rear of the computer that is used with a Category 3 or<br />
Category 5 twisted-pair cable. Through this connector, you can attach an Ethernet<br />
network cable to the internal transceiver in your computer.<br />
Attention<br />
The 10BASE-T Ethernet and the 100BASE-TX Fast Ethernet cabling in the<br />
network must be Category 5 or higher to meet various standards, including<br />
electromagnetic compatibility.<br />
