Installation Steps
Step 1: Unpack the Industrial Fast Ethernet Switch.
Step 2: Check the DIN-Rail is screwed on the Industrial Fast Ethernet
Switch. (Please refer to DIN-Rail Mounting section for DIN-
Rail installation. If the DIN-Rail is not screwed on the
Industrial Fast Ethernet Switch.). If you want to wall mount
the Industrial Fast Ethernet Switch, then please refer to
Wall Mount Plate Mounting section for wall mount plate
installation.
Step 3: To hang the Industrial Fast Ethernet Switch on the DIN-
Rail track or wall, please refer to the Mounting Installation
section.
Step 4: Power on the Industrial Fast Ethernet Switch. (Please refer
to the Wiring the Power Inputs section for power input) The
power LED on the Industrial Fast Ethernet Switch will light
up. Please refer to the LED Indicators section for meaning of
LED lights.
Step 5: Prepare the twisted-pair, straight through Category 5 cable
for Ethernet connection.
Step 6: Insert one side of Category 5 cables into the Industrial Fast
Ethernet Switch Ethernet port (RJ-45 port) and another side
of category 5 cables to the network devices’ Ethernet port
(RJ-45 port), ex: Switch, PC or Server. The UTP port (RJ-45)
LED on the Industrial Fast Ethernet Switch will light up when
the cable connected with the network device. Please refer to
the LED Indicators section for LED light meaning.
Be sure the connected network devices support MDI/
MDI-X. If it does not support then use the crossover
category 5 Cable.
Note
Step 7: Insert fiber cable from the ISW-511/621 series to the fiber
network. TX, RX must be paired at both ends. The optical
port LED on the Industrial Fast Ethernet Switch will light up
when the cable connected with the network device. Please
refer to the LED Indicators section for LED light meaning.
Step 8: When all connections are all set and LED lights all show in
normal, the installation is complete.

4. SwITCh OpeRATION
4.1 Address Table
The Industrial Fast Ethernet Switch is implemented with an address
table. This address table composed of many entries. Each entry is used
to store the address information of some node in network, including
MAC address, port no, etc. This information comes from the learning
process of Industrial Fast Ethernet Switch.
4.2 Learning
When one packet comes in from any port. The Industrial Fast Ethernet
Switch will record the source address, port no. And the other related
information in address table. This information will be used to decide
either forwarding or filtering for future packets.
4.3 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
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.
4.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A
Store-and-Forward Industrial Switch stores the incoming frame in an
internal buffer, do the complete error checking before transmission.
24
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
4.5 Auto-negotiation
The STP ports on the Industrial Fast Ethernet Switch have built-
in “Auto-negotiation”. 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.

5. 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 bad
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 the Industrial Fast Ethernet Switch doesn’t connect to the
network
Solution:
Check per port LED on the Industrial Fast Ethernet Switch. Try another
