2. INSTALLATION
This section describes the functionalities of the Gigabit 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
The PLANET GSD-503/GSD-504 and GSD-803/GSD-804 are 10/100/1000Mbps
Gigabit Ethernet Switches in a compact housing for easily desktop placement.
With 5/8 ports respectively, non-blocking wire-speed performance and 10/16Gbps
internal switching fabric, the Switches can handle extremely large amounts of data
in a secure topology linking to a backbone or high capacity servers. The Switches
has 8K MAC Address table. The Switches offers wire-speed packets transfer
performance without risk of packet loss. The high data throughput of Switches
makes it ideal for most Gigabit environments, especially while network upgrades to
a Gigabit environment.
All RJ-45 copper interfaces support 10/100/1000Mbps Auto-Negotiation for optimal
speed detection through RJ-45 Category 6, 5 or 5e cables. Support is standard
for Auto-MDI/MDI-X that can detect the type of connection to any Ethernet device
without requiring special straight or crossover cables.
The Flow Control function allows your Gigabit Switch supported routers and servers
to directly connect to this Switch for fast, reliable data transfer.
2.1.1 Product Overview
The PLANET GSD-503/GSD-504 and GSD-803/GSD-804 are Gigabit Ethernet
Switches with 5/8 RJ-45 10/100/1000Mbps 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. The Gigabit ports with jumbo frame feature supported, can handle extremely
large amounts of data transmission in a secure topology linking to a backbone or
high-power servers.
The GSD-503/GSD-504 and GSD-803/GSD-804 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 8K

9
different MAC address and enables ltering and forwarding at full wire speed.

Power Notice:
1. The device is a power-required device, it means, it will not work till it is pow-
ered. If your networks should active all the time, please consider using UPS (Un-
interrupted 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 Gigabit 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.

12
2.2.1 Desktop Installation
To install the Switch on desktop, simply follow the next steps:
Step 1: Attach the rubber feet to the recessed areas on the bottom of the Switch.
Step 2: Place the Switch on desktop near an AC power source.
Step 3: 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 Specifications.
Step 4: Connect your Switch to network devices.
A. Connect one end of a standard network cable to the 10/100/1000 RJ-45 ports
on the Back of the Switch.
B. Connect the other end of the cable to the network devices such as printer serv-
ers, 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.
Step 5: Supply power to the Switch.
A. Connect one end of the power cable to the Switch.
B. Connect the 12V DC power adapter 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 increasing 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.
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

14
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
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. 1000Base-T can be only connected in Full-duplex mode.

4. TROUBLESHOOTING
This chapter contains information to help you solve problems. If the Switch is not
functioning properly, make sure the Gigabit Ethernet Switch was set up according
to instructions in this manual.
The per port LED is not lit
Solution:
Check the cable connection of the GSD-503/GSD-504 and GSD-803/GSD-804.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The GSD-503/GSD-504 and
GSD-803/GSD-804 is run at Auto-negotiation mode and if the partner is set to half
duplex, then the performance will be poor.
Per port LED is lit, but the trafc is irregular
Solution:
Check that the attached device is not set to dedicate 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 the Switch doesn’t connect to the network
Solution:
Check per port 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.
