Description of Hardware
10BASE-T/100BASE-TX Ports (SMC6724L2)
These ports are dual-speed RJ-45 ports. Ports 1 through 23 are labeled with an “x” to indicate that they have a built-in crossover (MDI-X). Workstations and servers can be connected to these ports with straight-through cable. Port 24 is switch-selectable (MDI-X or MDI). There is an associated switch that is used to enable and disable the crossover, so this port can always be connected to another hub or switch with straight-through cable. When connecting to another switch or a hub, you can also use straight-through cable to connect any port on the switch to a port on the attached device that does not have built-in wiring crossovers (MDI), or use crossover cabling. (See Appendix B for a pinout description of crossover cable.)
Each of these ports support auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually. Each port also supports auto-negotiation of IEEE 802.3x full-duplex flow control, so the switch can automatically prevent port buffers from becoming saturated.
