Cables

GE0/0 and GE0/1 ports:
10/100/1000Base-T use the Category 5e UTP or STP with the maximum transmission distance of 100 meters.
Straight-through cable : All wire pairs are in the same order on each end of the RJ45 cable. The straight-through cable is
used to connect a terminal device such as a PC or router to a hub or LAN switch.
Crossover cable : Pin 1 and pin 2 at one end of the cable correspond to pin 3 and pin 6 at the other end, respectively. The
crossover cable is used to connect two terminal devices, such as connecting a PC to a PC, and connecting a router to a
router.
If the port supports Auto-MDI/MDIX, both straight-through and crossover cables can be used.
Considering that you may customize cables, the following section describes how to wire straight-through and crossover
cables.
As shown in the following figure, the pins of the RJ-45 connector are numbered 1 to 8, counting from left to right when the
connector is viewed from the side without the latching tab.

For a straight-through cable, use the same wiring.
