PLANET GSD-805 is a Gigabit Ethernet Switch with non-blocking wirespeed performance and its metal housing is suitable for desktop
deployment for SOHO application.
The device is a power-required device which means
it will not work till it is powered. If your networks
should be active all the time, please consider using
UPS (uninterrupted power supply) for your device. It
will prevent you from network data loss or network
2.In some areas, 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.
All RJ45 copper interfaces support 10/100/1000Mbps auto-negotiation
for optimal speed detection through RJ45 Category 5, 5e or 6 cables.
It supports an auto-MDI/MDI-X feature which can detect the type of
connection to any Ethernet device without requiring special straightthrough or crossover cables.
2.2 Installing the Switch
The flow control function allows the Gigabit Ethernet Switch supported
routers and servers to directly connect to this device for a fast, reliable
data transfer.
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.
When the Gigabit Ethernet Switch receives power, the Power LED should
remain solid Green.

PLANET Gigabit Ethernet Switch can also automatically identify and
determine the correct transmission speed of half/full duplex mode. The
Gigabit Ethernet Switch 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.

2.1 Product Description
With 16Gbps internal switching fabric and 9K jumbo frame, the Gigabit
Ethernet Switch can handle extremely large amounts of data in a secure
topology linking to a backbone or high capacity servers. The high data
throughput of the device makes it ideal for most Gigabit environments,
especially network upgrades to a Gigabit environment.
Connection to the Gigabit Ethernet Switch requires UTP
Category 5 network cabling with RJ45 tips. For more
information, please see the Cabling Specification in
Appendix A.

Switch Specifications
Check the contents of your package for the following parts:
Switch could recognize up to 8K different MAC addresses and enables
filtering and forwarding at full wire speed.
This Gigabit Ethernet Switch does not need software
The Gigabit Ethernet Switch is implemented with an address table. This
address table consists of many entries. Each entry is used to store
the address information of some nodes in the network, including MAC
address, port no, etc. This information comes from the learning process
of the Gigabit Ethernet Switch.
3.2 Learning
When one packet comes in from any port, the Gigabit Ethernet
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 and Filtering
When one packet comes from some port of the Gigabit Ethernet Switch,
it will also check the destination address besides the source address
learning. The Gigabit Ethernet Switch will look up 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 Gigabit Ethernet Switch 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 coming in, then this packet will be
filtered, thereby increasing the network throughput and availability.
2.2.1 Desktop Installation
To install the Gigabit Ethernet Switch on desktop, simply follow the
steps below:
3.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A
Store-and-Forward Gigabit Ethernet Switch stores the incoming frame
in an internal buffer and does the complete error checking before
transmission. Therefore, packets transmitted to the destination are
without errors. It is the best choice when a network needs efficiency
and stability.
The Gigabit 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
the overall performance. An Ethernet Switching can be easily configured
in any Ethernet network environment to significantly boost bandwidth
using conventional cabling and adapters.
Owing to the learning function of the Gigabit Ethernet Switch, 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 Gigabit Ethernet Switch performs “Store and Forward”;
therefore, no error will occur for packets. More reliably, it reduces the
re-transmission rate and thus, no packet loss will occur.

3.5 Auto-Negotiation
Tx + (transmit)
Rx + (receive)
The STP ports on the Gigabit Ethernet Switch have built-in “AutoNegotiation”. 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 detecting the modes and
speeds of both devices connected, and both 10BASE-T and 100BASE-TX
devices can be connected with the port in either half- or full-duplex
mode. 1000BASE-T can be only connected in full-duplex mode.

EC Declaration of Conformity
This chapter contains information to help you solve issues. If the Gigabit
Ethernet Switch is not functioning properly, make sure the Gigabit
Ethernet Switch was set up according to instructions in this manual.
Thank you for purchase PLANET products. You can browse our online
FAQ resource at the PLANET Web site first to check if it could solve you
issue. If you need more support information, please contact PLANET
Media Converter support team.
The per port LED is not lit
Check the cable connection of the Gigabit Ethernet Switch.
Performance is bad
Check the speed duplex mode of the partner device. The Gigabit
Ethernet Switch is run in 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
The standard RJ45 receptacle/connector
There are 8 wires on a standard UTP/STP cable and each wire is colorcoded. The following shows the pin allocation and color of straightthrough cable and crossover cable connection:
Straight Cable
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8
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 Gigabit Ethernet Switch isn’t connected to the network
Check per port LED on the Gigabit Ethernet Switch. Try another port on
the Gigabit Ethernet 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 the power again.
