Ethernet 10Base-T Crossover Cable
Where used: To directly connect an Ethernet access card on an LS2020 switch to another device on the Ethernet, such as a workstation.Note Some MAUs (medium access units) have a built-in crossover function and, therefore, use straight-through cables instead of crossover cables. Ports on such MAUs are marked with the letter X.
Cisco Systems does not provide this cable; it is widely available from other sources.
Figure 3-27 shows a physical representation of the Ethernet 10Base-T (twisted pair) crossover cable and provides a schematic diagram of its pinout assignments.
