2. INSTALLATION
This section describes the functionalities of the Industrial Fast Ethernet
Switch’s components and guides how to install it on the desktop.
Basic knowledge of networking is assumed. Please read this chapter
completely before continuing.
In the following section, the term “Industrial Fast Ethernet Switch”
means the ISW-511 / ISW-621 series.
2.1 Product Description
The PLANET ISW-511 / ISW-621 series is 4-Port 10/100Mbps + 1/2
100FX Fiber Port Industrial Fast Ethernet Switch with non-blocking wirespeed performance and new slim type with IP 30 metal shape for easily
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 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 Auto-negotiation for
optimal speed detection through RJ-45 Category 5, 4 or 3 cables.
Support 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 ow control function allows Industrial Fast Ethernet Switch
supported routers and servers to directly connect to this device for fast,
reliable data transfer.

In this paragraph, we will describe how to install Industrial Fast
Ethernet Switch and the installation points for the attention.
Installation Steps
Note
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 DINRail 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.
Step 7: Insert ber cable from the ISW-511/621 series to the ber
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 ltering 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 ltered. 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.
Therefore, no error packets occurrence, it is the best choice when a
network needs efciency 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 congured in any Ethernet network environment to signicantly
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 lter packets whose destination address is on the
same segment as the source address. This connes network trafc 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 retransmission rate. No packet loss will occur.
4.5 Auto-negotiation
The STP ports on the Industrial Fast Ethernet Switch have builtin “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 trafc 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
port on the Industrial Fast Ethernet Switch Make sure the cable is
installed properly Make sure the cable is the right type Turn off the
power. After a while, turn on power again.
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
port on the Industrial Fast Ethernet Switch Make sure the cable is
installed properly Make sure the cable is the right type Turn off the
power. After a while, turn on power again.
