Description
The NSM-208G has 8 Ethernet Switching ports that support 10/100/1000 Base-T, with a 10/100/1000M auto-negotiation feature and auto MDI/MDIX function.
It can connect 8 workstations and automatically switches the transmission speed (10 Mbps or 100 Mbps or 1Gbps) for corresponding connections. The flow control mechanism is also negotiated. There is link/data rate LEDs for each port to aid trouble-shooting. Port connectors are shielded RJ-45.
This unit is supplied in an IP20 rugged, high-strength steel case capable of either DIN-Rail or Wall Mounting.
