DS-3D2228P Hardware Installation Manual

To use the electrical port, you can connect the electrical port and other Ethernet
devices with the direct-through or cross cable through the UTP port. In this case, the
corresponding optical port cannot be used. The numbering order of the pins in the UTP
port is the same as the console port.

Because 4 10/100/1000Base-T ports of DS-3D2228P support the MDI/MDIX
auto-identification of the cable, DS-3D2228P can adopt five classes of
direct-through/cross network cables when it connects other Ethernet terminals.
