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.
