Introduction

The NS-208A/NSM-208A has 8 Ethernet ports that
support 10/100 Base-TX, with a 10/100M auto
negotiation feature and auto MDI/MDI-X function.
All Ethernet ports have memory buffers that
support the store-and-forward mechanism, which
assures that data can be transmitted properly. The
NS-208A/NSM-208A supports advanced network
standards to optimize
reduce maintenance costs, and secure network
safety.
The flow control mechanism is also negotiated.
There is link/data rate LEDs for each port to aid
troubleshooting. Port connectors are shielded RJ-
45.
