    DSS-24 on a network. Refer to other sources for information about networking in general. All the information you need to install the DSS-24 is contained in this user guide. Organization Chapter 1, Introduction, gives and physical a functional overview of the DSS-24.

  • Page 8: Introduction

    The chapter is divided into several sections. Each section describes the features of the DSS-24. Many of the topics covered will be dealt with in more detail later in the manual.

  • Page 9: Front Panel

    The DSS-24 is designed for management at a glance. The LEDs on the front panel of the DSS-24 allow you to monitor performance at a glance. It is not necessary to connect to the DSS-24 in order to check performance or verify that a port is working.

    24 may be plugged in without having any or with all LAN segment cables connected. The power plug is located at the rear of the DSS-24. Plug the cable into the wall socket and plug the other end into the DSS-24. There is no on/off switch. The DSS-24 powers on when you plug the power cord into the three pronged power connector.

  • Page 18: Network Connections

    Crossover cable has a different pin arrangement at each end. Fast Ethernet does not tolerate incorrect pin arrangements. You must use the correct pin arrangement in order for the DSS-24 to work properly. See Figure 8 for an example of straight through and crossover cable.

The Spacebar is used to toggle to different settings. The Backspace key allows you to move backwards through the panels.

  • Page 26: Panels

    DSS-24 10/100 Auto Negotiation Switch User’s Guide Panels Each panel of the DSS-24 covers eight ports. You will have either two or three panels. There are no other menus or panels available. Each panel has four columns: Port, Physical, Flow Control and Link Status.

  • Page 27: Configuration Examples

    Configuration Examples The following figures give examples of possible configurations. The figures are examples. They are intended to illustrate the functions of the DSS-24. The settings displayed on your switch may be different. Remember that the DSS-24 is an unmanaged switch. The DSS-24 can be connected to the network with no configuration and it will automatically negotiate all speed and duplex settings.
  • Page 28 DSS-24 10/100 Auto Negotiation Switch User’s Guide Ports 1 and 2 have been connected to the network. The DSS-24 has auto negotiated the proper speed and duplex mode, displayed in Figure 11. No further configuration is necessary. Figure 11: Auto Negotiation The speed and duplex mode on port 1 has been manually set.

  • Page 29: Troubleshooting

    Check the LEDs on the DSS-24 to verify settings. The port settings on the DSS-24 and the port settings on the device you are connecting to must be the same in order for them to communicate. Check the speed and duplex setting on both the port and the device you are connecting to.
  • Page 30 DSS-24 10/100 Auto Negotiation Switch User’s Guide default value is that all ports auto negotiate the proper speed and duplex mode. If the port has been manually configured for a particular speed and duplex mode, verify that the speed and duplex mode of the port match the speed and duplex mode of the device you are connecting to.
