IDAN-LAN35Mx08HR-RJ Connectors
The IDAN-LAN35MH08HR-RJ and IDAN-LAN35ME08HR-RJ both feature an RJ-45 connector for each of the onboard Ethernet ports. Four are
on the front panel and four are on the rear panel. The connectors are standard RJ-45 female connectors and follow the 10/100/1000 Base-T
Ethernet pinout. They are designed to be used with Cat5e UTP (Unshielded Twisted Pair) or similar cables. The pinout of all eight connectors
is the same. The figure below shows the pin numbering when
looking into the connector
