completely before continuing.
2.1 Product Description
With concepts of "Easy to Install and use", "Compact-sized design",
and "Simple troubleshooting", PLANET SW-502/SW-802 provides
cost-conscious business and home users with the foundation of an
integrated system of small-office / home-office networking. The SW
502/SW-802 is the fancy-shape plastic models and just right for your
network of 10 to 50 users.
The SW-502/SW-802 Fast Ethernet Switch is a Simple and
cost-effective, highly reliable network switch. And 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 traffic, 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-502/SW-802 are Fast Ethernet switches with 5/8 RJ-45
10/100 Mbps 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 product also supports store-and-forward forwarding scheme to
ensure low latency and high data integrity, eliminates unnecessary
traffic 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 filtering and forwarding at
full wire speed.

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
filtering 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 filtered.
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 efficiency and stability.
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 configured in any Ethernet network environment to significantly
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 filter packets whose destination address is on
the same segment as the source address. This confines the 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.
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. 1000Base-T can be only connected in
Full-duplex mode.

4. TROUBLESHOOTING
This chapter contains information to help you solve problems. If Giga
Switch is not functioning properly, make sure the 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 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.
Why the Switch doesn't connect to the network
Solution:
Check the LNK/ACT LED on the Switch
Try another port on the Switch I
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.2 10/100Mbps, 10/100Base-TX
When connecting your 10/100Mbps 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::
