Appendix A
Connector Wiring
A.1 10/100/1000BaseT Connector
The RICi-622GE Gigabit Ethernet ports use either a fiber optic SFP interface or
electrical interface. If the Gigabit Ethernet ports use electrical interfaces, they
terminate in an RJ-45, 8-pin connector. The ports support MDI and MDIX modes.
Table A-1 lists the pin assignments if the port is operating in 10BaseT or
100BaseT mode.
Table
A-2 lists the pin assignments if the port is operating in 1000BaseT mode. If
autonegotiation is disabled (forced mode), you must swap the receive and
transmit pins.
