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.
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.
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.
DSS-24 10/100 Auto Negotiation Switch User’s Guide Side Panel There are two fans. The fans come on when the DSS-24 is powered on. The three holes on each side of the DSS-24 are used to attach the mounting brackets. There are heat vents located on the side opposite the fans. The fans and the heat vents help to cool the DSS-24.
The only way of changing the default settings is through a physical connection with an RS- 232 cable. The DSS-24 does not have an IP address. It can not be monitored using SNMP and RMON. Introduction...
Unpacking the DSS-24 Installation options and instructions Powering on the DSS-24 Unpacking the DSS-24 Open the box and carefully unpack the DSS-24. You should have all the items on the following checklist: DSS-24 10/100 Auto Negotiation Switch RS-232 DCE serial cable...
Crimpers to crimp cable as needed. RJ-45 connectors as needed. Desktop/Shelf Installation The dimensions of the DSS-24 are: 441 mm (17.44 inches) x 235 mm (9.25 inches) 63 mm (2.44 inches). The measurements include the 8 mm (.31 inch) rubber feet.

DSS-24 10/100 Auto Negotiation Switch User’s Guide Rack Installation The DSS-24 can be mounted in an EIA standard size 19 inch rack. The dimensions are: 441 mm (17.44 inches) x 235 mm (10.03 inches) x 55 mm (2.16 inches), 1.25 U. DSS-24 can be placed in a wiring closet along with other equipment.

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.
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 MDI-II Uplink port allows you to use a straight through cable when connecting another switch to the DSS-24. If the MDI-II Uplink port is in use, you must use a crossover cable when connecting another switch or other device that requires a crossover connection, to the DSS-24.
DSS-24 10/100 Auto Negotiation Switch User’s Guide The LED panel of the DSS-24, displayed in Figure 9, is designed to give you critical information at a glance. The LEDs indicate the following: Power Link Activity Collision Speed All LEDs are described in detail. See Table 2: Per Port LEDs, to determine the meaning of each LED.

The connection times out after five minutes. Press Enter to reestablish the connection. This setting cannot be changed or disabled. If you have not done anything on the DSS-24 for more than five minutes, it will time out. Press Enter one time to refresh the screen.
DSS-24 10/100 Auto Negotiation Switch User’s Guide Panel Conventions The following panel conventions are used on the DSS-24: The Arrow and Tab keys can be used to select items. The Spacebar is used to toggle to different settings. The Backspace key allows you to move backwards through the 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.
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.
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.
