Rear panel

The rear panel of the NP2008 switch has eight auto-sensing 10/100 Mbps
Ethernet ports and a power jack for connection of the supplied plug-pack.

RJ-45 Network ports

All of the ports on the NP2008 are 10/100 Mbps capable auto-sensing
Ethernet ports. Each port supports only unshielded twisted pair (UTP) cable
using an 8-pin RJ-45 plug. The NP2008 provides an UP-Link feature for cas-
cading multiple switches. Port 8 can been configured as a normal switch port
or as an UP-Link port utilising the UP-Link selection switch .
