DSS-24 10/100 Auto Negotiation Switch User's Guide Ports There are three types of ports on the DSS-24: RS-232, MDI-II Uplink, and MDIX. 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. Network Connections 15
