2. INSTALLATION
This section describes the functionalities of the Desktop 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
With concepts of “Easy to Install and use”, “Compact-sized
design”, and “Simple troubleshooting”, PLANET SW-504/SW-804
provides cost-conscious business and home users with the foundation
of an integrated system of small-ofce / home-ofce networking. The
SW-504/SW-804 is the fancy-shape plastic models and just right for
your network of 10 to 50 users.
The SW-504/SW-804 Desktop Fast Ethernet Switch is a Simple
and cost-effective, highly reliable network Switch. And it is the ideal
device for bridging Ethernet to Fast Ethernet workgroups or networks.
Therefore, the Switches will be the fast being recognized as one of the
most important building blocks for today networking technology.
To segment the network, ease the network trafc, the 5/8-Port
10/100Mbps are useful for the SOHO switched networks as the friendly
network backbone. Provides array LED indicators, the network status
can be monitored at a glance.
2.1.1 Product Overview
PLANET SW-504/SW-804 are Desktop Fast Ethernet Switches with
5/8 RJ-45 10/100Mbps ports for high-speed network connectivity. The
Switches can also automatically identify and determine the correct
transmission speed and half/full duplex mode of the attached devices
with its 5/8 ports.
This Desktop Fast Ethernet Switch also supports store-and-forward
forwarding scheme to ensure low latency and high data integrity,
eliminates unnecessary trafc and relieves congestion on critical
network paths. With an intelligent address recognition algorithm, the
switches could recognize up to 1K different MAC address and enables
ltering and forwarding at full wire speed.

LNK/ACT Green
Lit: indicate the link through that port is
successfully established.
Blink: indicate that the Switch is actively
sending or receiving data over that port.
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 using 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 Switch from being damaged by unregulated surge or
current to the Switch or the power adapter.
2.2 Installing the Switch
This part describes how to install your Desktop Fast Ethernet Switch
and make connections to it. Please read the following topics and
perform the procedures in the order being presented.
Note
This Switch does not need software configuration.

11
2.2.1 Desktop Installation
To install the Switch on desktop, simply follow the next steps:
Step1: Attach the rubber feet to the recessed areas on the bottom
of the Switch.
Step2: Place the Switch on desktop near a DC power source.
Step3: Keep enough ventilation space between the Switch and the
surrounding objects.
Note
When choosing a location, please keep in mind the
environmental restrictions discussed in Chapter 1,
Section 1.4 Product Specification.
Step4: Connect your Switch to network devices.
A. Connect one end of a standard network cable to the 10/100
RJ-45 ports on the Back of the Switch.
B. Connect the other end of the cable to the network devices
such as printer servers, workstations or routers…etc.
Note
Connection to the Switch requires UTP Category 5
network cabling with RJ-45 tips. For more information,
please see the Cabling Specification in Appendix A.
Step5: Supply power to the Switch.
A. Connect one end of the power cable to the Switch.
B. Connect the power plug of the power cable to a standard wall
outlet.
When the Switch receives power, the Power LED should remain solid
Green.

3. SWITCH OPERATION
3.1 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. This information comes from the learning process of Ethernet
Switch.
3.2 Learning
When one packet comes in from any port, the 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.
3.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching,
it will also check the destination address besides the source address
learning. The Ethernet Switching 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 Switching 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 increase the network throughput and availability.
3.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A
Store-and-Forward Ethernet Switching 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 efciency and stability.

13
The 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 Ethernet switching, 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 the network trafc 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.
3.5 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 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)

4. TROUBLESHOOTING
This chapter contains information to help you solve issues. If Desktop
Fast Ethernet Switch is not functioning properly, make sure the Desktop
Fast Ethernet Switch was set up according to instructions in this
manual.
Some stations cannot 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
information.
Performance is bad Solution:
Check the speed duplex mode of the partner device. If the partner is
set to half duplex, then the performance will be poor.
Why the Switch doesn’t connect to the network Solution:
Check the LNK/ACT LED on the Switch
Try another port on the 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

A.1 Switch’s RJ-45 Pin Assignments
When connecting your Desktop Fast Ethernet Switch to another switch,
a bridge or a hub, a straight or crossover cable is necessary. Each port
of the Switch supports auto-MDI/MDI-X detection. That means you can
directly connect the Switch to any Ethernet devices without making a
crossover cable. The following table and diagram show the standard RJ-
45 receptacle/ connector and their pin assignments:
