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.

2.1 Product Description

PLANET ISW-511 / ISW-621 series and ISW-511T / ISW-621T series
are 4-Port 10/100Mbps + 1/2 100FX Fiber Port Industrial Fast Ethernet
Switch with non-blocking wire-speed performance and new slim
type with IP30 metal case for easy deployment in Heavy Industrial
demanding environments.

With 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 RJ45 copper interfaces support 10/100Mbps auto-negotiation for
optimal speed detection through RJ45 Category 5, 4 or 3 cables. With
auto-MDI/MDI-X, it can detect the type of connection to any Ethernet
device without requiring special straight-through 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.

2.1.3 Switch Upper Panel

The upper panel of the Industrial Fast Ethernet Switch consists of one
terminal block connector within two DC power inputs. Figure 2-6 shows
the upper panel of the Industrial Fast Ethernet Switch.

Figure 2-6 Industrial Fast Ethernet Switch Upper Panel.

2.1.4 Wiring the Power Inputs

The 6-contact terminal block connector on the top panel of Industrial
Fast Ethernet Switch is used for two DC redundant powers input.
Please follow the steps below to insert the power wire.

1. Insert positive / negative DC power wires into contacts 1 and 2 for

POWER 1, or 5 and 6 for POWER 2.

V1- V1 + V2 - V2 +

2. Tighten the wire-clamp screws for preventing the wires from

loosening.

The wire gauge for the terminal block should be in the

Note

range between 12 and 24 AWG.

2.1.5 Wiring the Fault Alarm Contact

The fault alarm contacts are in the middle of the terminal block
connector as the picture shows below. Inserting the wires, the
Industrial Fast Ethernet Switch will detect the fault status of the power
failure, or port link failure (available for managed model) and then
forms an open circuit. The following illustration shows an application
example for wiring the fault alarm contacts.

Insert the wires into the fault alarm contacts

1. The wire gauge for the terminal block should be in
the range between 12 and 24 AWG.

Note

2. Alarm relay circuit accepts up to 30V, max. 3A
currents.

the Wiring of 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 LED status.

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 (RJ45 port) and the other to
the network devices' Ethernet port (RJ45 port), e.g., Switch,
PC or Server. The UTP port (RJ45) LED on the Industrial Fast
Ethernet Switch will light up when the cable is connected with
the network device. Please refer to the LED Indicators section
for LED status.

Make sure the connected network devices support MDI/
MDI-X. If the network devices do not support MDI/

Note

MDI-X, please use the crossover Category 5 cable to
connect.

Step 7: Insert ber cable from the ISW-511 / 621 series or

ISW-511T / ISW-621T 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
is connected with network device. Please refer to the LED
Indicators section for LED status.

Step 8: When all connections are set and all LEDs are lit without any

issue, 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 is composed of many entries. Each entry is
used to store the address information of some node in the 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 from any port of Industrial Fast Ethernet
switch, 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 look up the
address table for the destination address. If not found, this packet will
be forwarded to all the other ports except the port where this packet
comes in. And these ports will transmit this packet to the network if
connected. If found and the destination address is located at a 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 where this packet

comes in, then this packet will be ltered.

27

4.4 Store-and-Forward

Store-and-Forward is one type of packet-forwarding techniques. A
Store-and-Forward Industrial Switch stores the incoming frames
in an internal buffer and checks any error from the frames before
transmission. No error packets occurrence, it is the best choice when

a network needs efciency 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 congured in any Ethernet network environment to signicantly

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 connes network trafc 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
detecting the modes and speeds at the second of both devices that are
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 Link LED is not lit

Solution:

Check the cable connection of the Industrial Fast Ethernet Switch.

Link LED is lit, but the trafc is irregular

Solution:

Check whether the attached device is not set to dedicated 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:

1. Check every port LED on the Industrial Fast Ethernet Switch.

2.Try another port on the Industrial Fast Ethernet Switch to make sure
the cable is installed properly while making sure the cable is the
right type.

3. Turn off the power and turn on the power again after a while.
