  • Page 9: Overview Of This User's Guide

    Overview of this User’s Guide Chapter 1, Introduction. Describes the Switch and its features. Chapter 2, Unpacking and Setup. Helps you get started with the basic installation of the Switch. Chapter 3, Identifying External Components. Describes the front panel, rear panel and LED indicators of the Switch.

  • Page 10: Introduction

    NTRODUCTION This chapter describes the features of the Switch and some background information about Ethernet/Fast Ethernet switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times.

    other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training. Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the address level Ethernet...
  • Page 12 For Fast Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks.

  • Page 13: Features

    Features The Switches were designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. The Switches with their small, compact size were specifically designed for small to middle range workgroups.
  • Page 14 workgroups can connect to the Switches now, and change adapters and hubs anytime later without needing to change the Switches or reconfigure the network. The Switches combine dynamic memory allocation with store-and-forward switching to ensure that the buffer is effectively allocated for each port, while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss.

  • Page 15: Unpacking And Setup

    Flow control for any port. This minimizes dropped packets by sending out collision signals when the port’s receiving buffer is full. Note that flow control is only available in half duplex mode. Data forwarding rate per port is at wire-speed for 100Mbps speed.

  • Page 16: Unpacking

    Unpacking Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items: One 8-port 10/100M NWay Fast Ethernet Switch One external power adapter This User’s Guide If any item is found missing or damaged, please contact your dealer for replacement.
  • Page 17 Make sure that there is proper heat dissipation and adequate ventilation around the Switch. Do not place heavy objects on the Switch.

  • Page 18: Identifying External Components

    DENTIFYING XTERNAL OMPONENTS This section identifies major external components of the hub. Both the front and rear panels are shown, followed by a description of each panel feature. The indicator panel is described in detail in the next chapter. Front Panel The figure below shows the front panel of the switch.
  • Page 19 8-port Fast Ethernet 10/100M NWay Switch DC Power Jack: Power is supplied through an external AC power adapter. Check the technical specification section for information about the AC power input voltage. Since the switch does not include a power switch, plugging its power adapter into a power outlet will immediately power it on.
  • Page 20 Uplink Jack(s) (MDI-II): Use this jack to connect stations to the hub. This is MDI-II (Medium- dependent Interface, straight-wired) jack, which means you can connect the hub to a device with a MDI-X port using an ordinary straight-through cable, making a crossover cable unnecessary.
