Introduction

The FSD-401ST/FSD-401SC, 5-port 10/100Mbsp Ethernet Switch is
designed to allow simultaneous transmission of multiple packets via an
internal high-speed data channel including 100Base-FX fiber-optic.
This means that it can partition a network more efficiently than bridges
or routers in most environments.

FSD-401 User's Manual 3

In the following sections, the term “Switch” will represent Planet’s
FSD-401, the both model, and “switch” for third part Ethernet switches.
This Switch is a highly reliable network switch and is the ideal device
for bridging Ethernet to Fast Ethernet workgroups or networks. Simple
and cost-effective, the Switch complies to IEEE802.3u, IEEE802.3,
100Base-FX, 100Base-TX, and 10Base-T. Therefore, the Switch will
be the fast being recognized as one of the most important building
blocks for today networking technology.

Compact in size and designed for Plug and Play installation, the Switch
allows the network administrator to simply connect the network and
power cables and the switching/bridging functions begin automatically.
No hardware or software configurations are required.

The front panel of the Switch provides LED indicators for easy
recognition of the switch operation status and for troubleshooting.
These LED indicators display the power status for the system and link,
speed, full-duplex, and receive status for each port.

With 4-port Fast Ethernet Switching designed specifically for
connecting workgroup devices and desktops, companies no longer
have to invest in expensive and inflexible switches engineered
primarily for backbone implementations. Instead, companies can
deploy scaleable, affordable switches that increase the aggregate
bandwidth of the network by boosting throughput to the workgroups

Power Notice:

1. The device is a power-required device, it means, it will not work till

it is powered. If your networks should active all the time, please
consider use an UPS (Uninterrupted Power Supply) for your device.
It will prevent you from network data loss or network downtime.

2. In some area, installing a surge suppression device may also help to

protect your hub from being damaged by unregulated surge or
current to the Switch or the power adapter.

Hardware Installation

1. Place the Switch on a smooth surface

2. Connect the power cord to the switch and with the other end to the

power.

3. Connect hub or PC to one port of the Switch using Category 3/4/5

UTP/STP cabling.

4. Connect another hub or PC to the other port of Switch by following

the same process as described in Step 3.

5. Connect the multi-mode fiber cable (62.5/125ì m or 50/125ì m)

with correct connector (either ST or SC) from the Switch to your
100Bas-FX Ethernet device (with TX/RX crossed)

6. Set the duplex mode of the Switch and the fiber device. Power on

FSD-401 User's Manual 9

the Switch and all the devices connect to the Switch.

Notice:

1. Cable distance for the Switch

The UTP cable distance between the Switch and hub/PC should
not exceed 100 meters. The fiber-optic cable should not exceed
412 meters in Half-duplex mode and 2 kilometers for Full­duplex mode.

2. Make sure the wiring is correct

It can be used Category 3/4/5 cable in 10Mbps operation. To
reliably operate your network at 100Mbps, you must use an
Unshielded Twisted-Pair (UTP) Category 5 cable, or better Data
Grade cabling. While a Category-3 or -4 cable may initially
seem to work, it will soon cause data loss.
The fiber-optic cable should be a multi-mode fiber cable with

62.5/125ì m or 50/125ì m in specification. You can find the
information from the printing of the cable. If you are not familiar
with it, please consult your local dealer for the information.

All kinds of hub/PC can connect to Switch by using straight-through
wires. The Switch provides one additional RJ-45 connector that is
converted from port 1, labeled “Uplink” port. Either port 1 or Uplink
port can be used at one time.

Switch Operation

Address Table

The 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. The information comes from the learning process of Ethernet
Switch.

Learning

When one packet comes in from any port. The Ethernet Switch will
record the source address, port no. and the other related information in
address table. These information will be used to decide either
forwarding or filtering for future packets.

Forwarding & Filtering

When one packet comes from some port of the Ethernet Switch, it will
also check the destination address besides the source address learning.

SOHOConnect Series12

The 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 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, when 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-and-Forward Ethernet 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 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. A Ethernet Switch can be easily

FSD-401 User's Manual 13

cofigured in any Ethernet network environment to significantly boost
bandwidth using conventional cabling and adapters.

Due to the learning function of the 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 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 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 100Base-TX port in either
Half- or Full-Duplex mode.

If attached device is: 100Base-TX port will set to:

• 10Mbps, no auto-negotiation 10Mbps

• 10Mbps, with auto-negotiation 10/20Mbps (10Base-T/Full-Duplex)

SOHOConnect Series14

• 100Mbps, no auto-negotiation 100Mbps

• 100Mbps, with auto-negotiation 100/200Mbps

(100Base-TX/Full-Duplex)

Troubleshooting

This chapter contains information to help you solve problems. If the
Switch is not functioning properly, make sure the Switch was set up
according to instructions in this manual.

The Link LED is not Lit

Solution:
Make sure the switch configuration is consistent with the connecting
device
Check the cable connections.

Performance is bad

Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet
Switch is set to full duplex and the partner is set to half duplex, then
the performance will be poor.

Some stations can not talk to other stations located on the other
port

Solution:
The address table may contain older information than of the address
table of that node. Please power down to refresh the address
