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.
