Introduction
The FSD-8080/1600, 8/16-port 10/100Mbsp Ethernet Switch is
designed to allow simultaneous transmission of multiple packets

SOHOConnect Series2
via an internal high-speed data channel. This means that it can
partition a network more efficiently than bridges or routers
in most environments.
In the following sections, the term “Switch”will represent
Planet’s FSD switch, 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-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.

FSD-8080/1600 User's Manual 3
With 8-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 that need it most.

Power
(PWR) Green This indicator lights green when the hub is receiving power, otherwise, it is off.
Link/ Act Green This indicator green when the port is
connected to a either 10Mbps Ethernet or
100Mbs Fast Ethernet station , If the station
to which the hub is connected is powered
off, or if there is a problem with the link, the
LED will remain off.
And the indicator blinking green when the
data will be received to all other connected
ports.

connected is powered off, a 10Mbps
Ethernet station, or if there is a problem with
the link, the LED will remain off.
FDX/COL Amber Lit: Full duplex operation

Blink: indicates data collisions on the
respective Ethernet segment of this port.
Whenever a collision is detected, the
respective COL indicator will briefly blink
Rear Panel
The rear panel of the Switch indicates a DC-jack power socket,
which accepts exactly DC 12V, 1A power from the output of the
AC adapter connected to your local AC power outlet. And one

Hardware Installation
1. Place the Switch on a smooth surface
2. Connect the output cord of power supply to the DC-jack.
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.
Notice:
Cable distance for FSD-8080/1600
The cable distance between the Switch and hub/PC should
not exceed 100 meter.
Make sure the wiring is correct
It can be used Category 3/4/5 cable in 10Mbps operation.

FSD-8080/1600 User's Manual 9
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.
All kinds of hub/PC can connect to switch by using straight-
through wires. The hub provides one additional RJ45 connector
which is converted from port 1, labeled “Uplink”port. Either port
1 or Uplink port can be used at one time.
Configuration
100Mbps Server to 10Mbps Hub
Plug one end of the Category 5 UTP Cable into any one port of
the Switch, and the other end of this cable into the RJ-45 of Fast
Ethernet Adapter in the server. The cable length between these 2
connecting points should not exceed 100 meters.
Plug one end of the Category 3 UTP Cable into “Uplink”port of
the Switch, and the other end of this cable into any port of the
10Mbps Ethernet hub. The cable length between these 2
connecting points should not exceed 100 meters.

SOHOConnect Series10

Plug one end of the Category 5 UTP Cable into one port of the
Switch, and the other end of this cable into “Uplink”port of the
100Mbps Fast Ethernet Hub. The cable length between these 2
connecting points should not exceed 100 meters.
Plug one end of the Category 3 UTP Cable into one port of the
Switch, and the other end of this cable into “Uplink”port of the
10Mbps Ethernet Hub. The cable length between these 2
connecting points should not exceed 100 meters.

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

SOHOConnect Series12
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. 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 availablity
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.

FSD-8080/1600 User's Manual 13
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 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.

SOHOConnect Series14
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)
•100Mbps, no auto-negotiation 100Mbps
•100Mbps, with auto-negotiation 100/200Mbps
(100Base-TX/Full-Duplex)
