Introduction SOHOware™ Super Flex Congratulations on choosing a SOHOware™ Super Flex 10/100Mbps Auto sensing Dual-Speed Hub. The hubs are designed especially for small offices, corporate branch offices, small businesses and work groups in large/medium enterprises that need to integrate 10Mbps Ethernet and 100Mbps Fast Ethernet networks and need dedicated connections to servers or other hubs/switches.
+ Store-and forward switching between 10Mbps and 100Mbps networks; protects against data-error and enhances effective network traffic + Front panel LED indicators; troubleshooting at a glance + Automatic MAC address leaning; maintains full data transfer performance within segments as well as to extended segments + Complies with IEEE 802.3 [0 Base-T and 802.3u base's-TX.

Super Flex hubs are designed to auto negotiate the speed and duplex capability of the connected device. For various reasons a connected network device may sometimes fail to respond to the auto negotiation mechanism, therefore a DIP (Dua Inline Package) switch is provided to allow users to manually adjust the Tx/Rx speed. The default setting is auto negotiation with four pins positioned as shown below: N OFF 12 3 4 Figure 3.

Getting Started Placing Considerations Super Flex hubs should be placed where they will not be subjected to extreme temperatures, humidity, or excessive electromagnetic interference. Do not block the ventilation holes on the side, or the exhaust port on the rear of the Super Flex. Installing Your Super Flex Hub Installation couldn’t be easier. Only three steps and you're in business: 1. Plug: Plug the cable of the connected device to the port of the Super Flex 2.
¥ When the switch port is set to the Normal position, it can be used to connect to a server, a hub, or another switch that has UP LINK selected NDS316 v' When a device is connected to a switch UP LINK port it is usually used to connect t0 a hub or to another switch that does not have UP LINK selected ¥ When a device is connected to a SWITCH port it can be used to connect 4 server, a hub, or another switch that has Up link selected = Note: One of the devices, either the connected hub/switch or Super Flex, mu
C. Connecting a Super Flex Hub to a Switch NDS108 Either the connected switch or the Super Flex must be set 10 the UP LINK position. When you connect a Super Flex hub to a Switch, for example a SOHOware™ Plug-n-Switch, set the Switch port of the NDS108 to the UP LINK position. If the connecting device supports full-duplex you will get guaranteed 200Mbps bandwidth for the Switch-to-Switch connection, The Switch port on the connecting device is left in the Normal position.
Application Scenarios This section gives some examples of how to locate the Super Flex hubs so 2s to achieve the maximum performance from your networking hardware. Scenario I: Integrating 10Mbps and 100Mbps When small offices are faced with network migration from 10Mbps Ethernet ta 100Mbps Fast Ethernet, SOHO ware™ Super Flex lets legacy 10Mbps Ethernet equipment coexist and communicate with new, faster 100Mbps Fast Theme devices.
Scenario lll: Multiple Mixed Networks Connect a combination of multiple Super Flex hubs along with regular hubs and tenseness switches to create a flexible “virtual non-blocking” switched work group LAN; at an implementation cost of only a small fraction of other competitive schemes. Regular client PCs connect to the Super Flex hubs, enjoying “virtual non-blocking” switch performance due to the very low probability of collisions.
LED Indicators The LED indicators will help you monitor the status of each port and the connected segments. The basic functions of the LED indicators are given below. More detailed explanations are on the following pages.
