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
trafc 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 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 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.
Note
This Switch does not need software configuration.
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 front of the Switch.

11
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.
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
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.
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

13
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 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 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 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.
