Installation
This section describes the functions of the Industrial Fast Ethernet Switch's
components and guides you how to install it on the desktop. Basic knowledge of
networking is assumed. Please read this chapter completely before continuing.
Product Description
The IFS MC-4TX1FXMM-2km,/MC-4TX2FX series are 4-Port 10/100Mbps + 1/2
100FX Fiber Port Industrial Fast Ethernet Switches with non-blocking wire-speed
performance and a new slim type chassis with an IP 30 metal shape for easy
deployment in Heavy Industrial demanding environments.
With a 1/1.2Gbps internal switching fabric, the Industrial Fast Ethernet Switch
can handle extremely large amounts of data in a secure topology linking to a
backbone or high capacity servers.
The Industrial Fast Ethernet Switch has 2K MAC address table and offers wirespeed packet 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 Auto-negotiation for optimal
speed detection through RJ-45 Category 5, 4 or 3 cables. Support is standard for
Auto-MDI/MDI-X that can detect the type of connection to any 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.

Switch Operation
Address Table
The Industrial Fast Ethernet Switch is implemented with an address table. This
address table is composed of many entries. Each entry is used to store the
address information of some node in the network, including MAC address, port
number, etc. This information comes from the learning process of Industrial Fast
Ethernet Switch.
Learning
When one packet comes in from any port the Industrial Fast Ethernet Switch will
record the source address, port number, and the other related information in the
address table. This information will be used to decide either forwarding or filtering
for future packets.
Forwarding & Filtering
When one packet comes from some port of the Industrial Fast Ethernet Switch, it
will also check the destination address besides the source address learning. The
Industrial Fast Ethernet Switch will lookup the address-table for the destination
address. If not found, this packet will be forwarded to all the other ports except
the port, which this packet comes in. And these ports will transmit this packet to
the network it connected. If found, and the destination address is located at
different port from this packet comes in, the Industrial Fast Ethernet Switch will
MC-4TX Se
ries Industrial Ethernet Switch User Manual 21
Chapter 4: Switch Operation
forward this packet to the port where this destination address is located
according to the information from address table. But, if the destination address is
located at the same port with this packet comes in, then this packet will be
filtered. Thereby increasing the network throughput and availability.
Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-andForward Industrial Switch stores the incoming frame in an internal buffer, do the
complete error checking before transmission. Therefore, no error packets
occurrence, it is the best choice when a network needs efficiency and stability.
The Industrial Fast Ethernet Switch scans the destination address from the
packet-header, searches the routing table provided for the incoming port and
forwards the packet, only if required. The fast forwarding makes the switch
attractive for connecting servers directly to the network, thereby increasing
throughput and availability. However, the switch is most commonly used to
segment existing hubs, which nearly always improves overall performance. An
Ethernet Switching can be easily configured in any Ethernet network environment
to significantly boost bandwidth using conventional cabling and adapters.
Due to the learning function of the Industrial Fast Ethernet Switch, the source
address and corresponding port number of each incoming and outgoing packet
are stored in a routing table. This information is subsequently used to filter
packets whose destination address is on the same segment as the source
address. This confines network traffic to its respective domain, reducing the
overall load on the network.
The Industrial Fast Ethernet Switch performs "Store-and-Forward" therefore, no
error packets occur. More reliably, it reduces the re-transmission rate. No
packet loss will occur.
Auto-negotiation
The STP ports on the Industrial Fast Ethernet Switch have built-in "Autonegotiation". This technology automatically sets the best possible bandwidth
when a connection is established with another network device (usually at Power
On or Reset). This is done by detect the modes and speeds at the second of
both device is connected and capable of, both 10Base-T and 100Base-TX
devices can connect with the port in either Half- or Full-Duplex mode.

Troubleshooting
This chapter contains information to help you solve issues. If the Industrial Fast
Ethernet Switch is not functioning properly, make sure the Industrial Fast
Ethernet Switch was set up according to instructions in this manual.
The per port LED is not lit
Solution:
Check the cable connection of the Industrial Fast Ethernet Switch.
Performance is poor
Solution:
Check the speed duplex mode of the partner device. The Industrial Fast Ethernet
Switch is run at Auto-negotiation mode and if the partner is set to half duplex,
then the performance will be poor.
Per port LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices
use a physical or software switch to change duplex modes. Auto-negotiation may
not recognize this type of full-duplex setting.
Why doesn’t the Industrial Fast Ethernet Switch connect to the network?
Solution:
Check per the port LED on the Industrial Fast Ethernet Switch. Try another port
on the Industrial Fast Ethernet Switch Make to sure the cable is installed
properly. Make sure the cable is the right type. Turn off the power. After a
while, turn the power back on.
