DSS-24 10/100 Auto Negotiation Switch User’s Guide

Network Connections

Ports

There are three types of ports on the DSS-24: RS-232, MDI-II Uplink, and MDI-

RS-232 Port

The RS-232 port, located at the rear, is used to configure the DSS-24.

Follow these steps to connect the DSS-24 and a workstation or laptop:

1. Plug one end of the cable provided into the port.

2. Plug the other end into the workstation or laptop.

3. Run HyperTerminal or a terminal emulation program using the

settings given for Local Console Management at the beginning of

Chapter 5, Managing the DSS-24.

MDI-II Uplink Port

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.

Follow these steps to connect a device to the MDI-II Uplink port:

1. Plug one end of a cable into the uplink port.

2. Plug the other end into any port except an uplink port on the other

device.

MDI-X Ports

The remaining ports are crossover ports. The pin arrangement is the same as the

arrangement in a crossover cable. The advantage of MDI-X ports is that you can

connect a device with an MDI-II port without using a crossover cable. The steps

for connecting the DSS-24 to 10 Mbps devices or 100 Mbps devices are the same.

All the ports will auto negotiate the proper speed and duplex mode.

Follow these steps to connect cables to the DSS-24:

1. Plug one end of the cable into any of the MDI-X ports.

2. Plug the other end into the appropriate port on the other device.

3. Verify that the LED indicates connection at the proper speed and

duplex mode.
