10/100
The 10/100 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts with internal crossovers. These ports
have the send (TD) and receive (RD) signals internally crossed so that a twisted-pair straight-through cable and adapter
can be attached.

When connecting 10/100 ports to devices such as servers, workstations, and routers, you can use a two or four
twisted-pair straight-through cable wired for 10BASE-T and 100BASE-TX.

When connecting the ports to other devices, such as switches or repeaters, you can use a two or four twisted-pair
crossover cable. Figure 60 on page 77
