Making Twisted-Pair
Attachments
You can make twisted-pair attachments to the Switch by first installing DES-108TX modules. The system can be configured to have a maximum of eight switched twisted-pair ports. Each of these ports support N-Way or 100Mbps full-duplex force mode.
Depending on the node you are connecting to a twisted-pair port, you will need either a straight or crossover twisted-pair cable. For connection to a hub, you will need a crossover twisted-pair cable; for connection to other network devices such as servers and switches, you will need a crossover cable. A crossover cable is almost the same as an ordinary twisted-pair cable only that the pin configuration of a crossover cable is crossed over. Maximum cable length is 100 meters.
For information on cable pin configuration, see Appendix B, Cables and Connectors.
NOTE: You do not need to turn off the Switch when making network connections; just plug in the cables into the ports.
To make twisted-pair attachments to the Switch, follow these steps:
1.Depending on the number of twisted-pair attachments you want to create, install the appropriate number of DES-108TX modules into the Switch. Take note that each module provides two switched twisted-pair ports. For information on the installation procedure, see the Port Module Installation section of Chapter 3, Installation.
2.Obtain the cable needed in the connection; that is, straight cable for connection to a server, crossover twisted-pair for other devices. Ensure that this cable does not exceed 100 meters.
