2.1 Product Description

PLANET’s GSD-801 and GSD-501 is 8/5 ports 10/100/1000Mbps Ethernet switches in a compact housing for easily desktop placement or wall-mounting.

GSD-801 provides 16Gbps non-blocking switch fabric, 8k MAC Address table and GSD501 provides 10Gbps non-blocking switch fabric, 4k MAC Address table.

Both the GSD-801 and the GSD-501 are support 802.3x full duplex ow control and also offers wire-speed packet transfer performance without risk of packet loss.

All eight/ve RJ-45 copper interfaces support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ-45 Category 3, 4, 5 or above cables. MDI/MDI-X auto detection is provided for direct wire connection to any Ethernet device without requiring cross-over cables.

2.1.1 Product Overview

PLANET GSD-801/501 is a gigabit Ethernet switch with 8/5 RJ-45 10/100/1000 Mbps ports for high-speed network connectivity. GSD-801/501 can also automatically identify and determine the correct transmission speed and half/full duplex mode of the attached devices with its 8/5 ports. The Gigabit port can handle large amounts of data transmission in a secure topology linking to a backbone or high-power servers.

This product 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, GSD-801/501 could recognize up to 8K/4K 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 a GSD-801/501

This part describes how to install your GSD-801/501 Gigabit Ethernet Switch and make connections to the switch. Please read the following topics and perform the procedures in the order being presented.

PLANET GSD-801/501 Gigabit Ethernet Switch do not need software conguration. To install your GSD-801/501 on a desktop or shelf, simply complete the following steps.

2.2.1 Desktop Installation

To install a GSD-801/501 on a desktop or shelf, simply complete the following steps:

Step1: Attach the rubber feet to the recessed areas on the bottom of the switch.

Step2: Place the GSD-801/501 on a desktop or shelf near an DC power source.

Step3: Keep enough ventilation space between the switch and the surrounding objects

Note: When choosing a location, please keep in mind the environmental re-

strictions discussed in Chapter 1, Section 4, Specification.

Step4: Connect your GSD-801/501 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 GSD-801/501.

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 Section 4, Specification.

Step5: Supply power to the Switch.

A. Connect one end of the power cable to the GSD-801/501

B. Connect the power plug of the power cable to a standard wall outlet.

When the GSD-801/501 receives power, the Power LED should remain solid Green.

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 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.

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.

The Link LED is not lit

Solution:

Check the cable connection and remove duplex mode of the Giga Switch

Some stations can not 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.
