NetComm NP3005 manual RJ-45 Network ports, Twisted pair cables

RJ-45 Network ports

All of the ports on the NP3005 are 10/100/1000 Mbps capable auto-sensing Ethernet ports. Each port supports only unshielded twisted pair (UTP) cable using an 8-pin RJ-45 plug. The Auto-uplink feature senses the connection of uplink (MDI-II) wiring using a straight-through twisted pair cable to any of the 5 ports on the NP3005 switch to allow for connection to any port of an addition switch or hub.
