Appendix A Switch's Rj45 Pin Assignments; 1000Mbps, 1000Base-T; 10/100Mbps, 10/100Base-Tx - Planet Networking & Communication igs-801m User Manual

A.1 1000Mbps, 1000BASE-T
Implicit implementation of the crossover function within a twisted-pair cable, or at a wiring panel, while not expressly forbidden,
is beyond the scope of this standard.
A.2 10/100Mbps, 10/100BASE-TX
When connecting your 10/100Mbps Ethernet Switch to another switch, a bridge or a hub, a straight-through or crossover cable
is 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 RJ45 receptacle/
connector and their pin assignments:
