Installation
This section describes the functionalities of the Industrial Fast
Ethernet components and guides how to install it on the
desktop. Basic knowledge of networking is assumed. Please
read this chapter completely before installation.
In the following section, the term “Industrial Fast Ethernet
Switch” means the MC251-4P/1S and the NS2051-4P/1T
Product Description
The IFS MC251-4P/1S and the NS2051-4P/1T are 5-Port
10/100Mbps with 4-Port PoE unmanaged Industrial Fast
Ethernet Switches and provide non-blocking wire-speed
performance in an IP-30 aluminum metal enclosure for easy
deployment in harsh Industrial demanding environments.
The PoE in-line power follow the standard IEEE 802.3af and
allows to power 4 PoE compliant devices at distance of up to
100 meters through the 4-pair Cat 5 / 5e UTP wire. With Data
and Power over Ethernet from one unit, the MC251-4P/1S
and the NS2051-4P/1T reduces cable deployment and
eliminates the need for dedicated electrical outlets on the wall,
ceiling or any hard to reach locations.
With 1Gbps internal switching fabric, the Industrial Fast
Ethernet Switch can handle large amounts of data in a secure
topology linking to a backbone or high capacity servers.
The Industrial Fast Ethernet Switch has a 2K MAC address
table and offers wire-speed packets transfer performance
without risk of packet loss. The stable throughput of the device
makes it ideal for most Ethernet environments.
All RJ-45 copper interfaces support 10/100Mbps Autonegotiation for optimal speed detection through RJ-45
Category 3, 4, 5, 5e or 6 cables. Support standard for AutoMDI/MDI-X that can detect the type of connection to any
4 IFS MC251-4P/1S and NS2051-4P/1T User Manual
Ethernet device without requiring special straight or crossover
cables.
The Flow Control function allows Industrial Fast Ethernet
Switch supported routers and servers to directly connect to
this device for fast, reliable data transfer.
