  • Page 7: Chapter 1 Hardware Installation And Network Topology

    Network Topology Overview The Intel Express 100BASE-TX Switching Hub is a 5-port Fast Ethernet switch featuring five 100BASE-TX ports and two slots for optional 100BASE-TX or 100BASE-FX media adapters. Each 100 Mbps port supports a Fast Ethernet segment, up to a total of 1024 cached nodes for the switch.

  • Page 8: Features

    C H A P T E R Intel Express 100BASE-TX Switching Hub Security features include the creation of custom filters and virtual networks (VLANs). You can define any custom filter based on multicast/broadcast, source port, destination port, and destination address. VLAN features include the ability to set broadcast or multicast domains.

  • Page 9: Installation And Setup

    C H A P T E R Hardware Installation and Network Topology Installation and Setup Install the switch in a rack or on a shelf. For rack placement, connect the switch to a 19-inch rack using the enclosed rack mount brackets. For shelf placement, attach the enclosed rubber feet to each corner of the bottom of the switch and place it on a flat, level surface.

    Different switch and repeater manufacturers implement their port configurations differently. The following guidelines are based on the Intel Express 100BASE-TX Switching Hub (switch), the Intel Express 100BASE-TX Stackable Hub (repeater) and the EtherExpress™ family of adapters (server or workstation). These apply to the majority...

  • Page 14: Typical Configurations

    In the 100 Mbps environment, workgroup clients should be connected to a 100 Mbps hub such as the Intel Express 100BASE-TX Stackable Hub. All hub stacks should be connected to the Express Switching Hub. By connecting the hubs to a switching environment, you can extend Fast Ethernet distance limitations.
