When connecting Switch to another Fast Ethernet switch, a straight or crossover
cable might necessary. Each port of the Switch supports auto-MDI/MDI-X detection.
That means you can directly connect the Switch to any Ethernet devices without
making a crossover cable. The following table and diagram show the standard RJ-
45 receptacle/ connector and their pin assignments:

There are 8 wires on a standard UTP/STP cable and each wire is color-coded. The
following shows the pin allocation and color of straight cable and crossover cable
connection:
