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.
