1. 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 A 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 and reduces the overall load on the network The Giga Switch performs Store and forward therefore no error packets occur More reliably it reduces the re transmission rate No packet loss will occur Auto Negotiation The STP ports on the GSD 1020 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 detecting the modes and speeds at the second of both device is connected and capable of Both 10Base T and 100Base TX devices can connec2. 10 100 1000Mbps Gigabit Fast Ethernet Switch GSD 1020 User s Manual Trademarks Copyright PLANET Technology Corp 2002 Contents subject to revision without prior notice PLANET is a registered trademark of PLANET Technology Corp All other trademarks belong to their respective owners Disclaimer PLANET Technology does not warrant that the hardware will work properly in all environments and applications and makes no warranty and representation either implied or expressed with respect to the quality performance merchantability or fitness for a particular purpose PLANET has made every effort to ensure that this User s Manual is accurate PLANET disclaims liability for any inaccuracies or omissions that may have occurred Information in this User s Manual is subject to change without notice and does not represent a commitment on the part of PLANET PLANET assumes no responsibility for any inaccuracies that may be contained in this User s Manual PLANET makes no commitment to update or keep current the information in this User s Manual and reserves the right to make improvements to this User s Manual and or to the products described in this User s Manual at any time without notice If you find information in this manual that is incorrect misleading or incomplete we would appreciate your comments and suggestions FCC Warning This equipment has been tested and found to comply with the limits for a Class A digital de
