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.  
In the following section, the term “Switch” means the Switch, GSD-800;  
term of “switch” can be any third part switches.  
2.1 Product Description  
The PLANET GSD-800 is a 10/100/1000Mbps Gigabit Ethernet Switch  
in a compact housing for easily desktop placement. With 8 ports  
respectively, non-blocking wire-speed performance and 16Gbps internal  
switching fabric, the Switch can handle extremely large amounts of data  
in a secure topology linking to a backbone or high capacity servers.  
The Switch has 8K MAC Address table. The Switch offers wire-speed  
packets transfer performance without risk of packet loss. The high data  
throughput of Switch 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 Ethernet Switch supported  
routers and servers to directly connect to this Switch for fast, reliable  
data transfer.  
2.1.1 Product Overview  
The PLANET GSD-800 is a Gigabit Ethernet Switch with 8 RJ-45  
10/100/1000Mbps ports for high-speed network connectivity. The  
Switch can also automatically identify and determine the correct  
transmission speed and half / full duplex mode of the attached devices  
with its 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-800 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 Switch could recognize up  
to 8K different MAC address and enables filtering 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 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 Gigabit Ethernet Switch and  
make connections to it. Please read the following topics and perform  
the procedures in the order being presented.  
This Switch does not need software configuration.  
Note  
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.  
When choosing a location, please keep in mind the  
environmental restrictions discussed in Chapter 1,  
Section 1.4 Product Specifications.  
Note  
Step 4: Connect your Switch to network devices.  
A. Connect one end of standard network cable to the  
a
10/100/1000 RJ-45 ports on the front of the Switch.  
10  
 
B. Connect the other end of the cable to the network devices  
such as printer servers, workstations or routers…etc.  
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.  
Note  
Step 5: Supply power to the Switch.  
A. Connect one end of the power cable to the Switch.  
B. Connect the 100-240V AC power cord 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  
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.  
There by 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  
12  
 
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 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 issues. 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-800.  
Performance is bad  
Solution:  
Check the speed duplex mode of the partner device. The GSD-800 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 traffic 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.
