CrossFire 8730 Switch Installation Guide, DOC-7046 v. 1.2 Cable and Pin Information
Fast Ethernet Ports
The Fast Ethernet ports use standard or crossover UTP-5 copper cables. The
maximum cable length is 100 m (328 feet).
Twisted-Pair Cable Pin-Outs
The Fast Ethernet ports use standard RJ-45 connectors and Ethernet pin-outs
without internal crossovers. Figure 14 shows the pin-out. When connecting the Fast
Ethernet ports to compatible servers and workstations, ensure that you use a
crossover cable wired for 10BaseT and 100BaseTX. When connecting to other
switches or repeaters, ensure that you use a straight-through cable.
