Cabling

The HiSpeed switch models are similar in physical makeup of ports and LEDs. This section describes the following port types, LED configurations, and connections for all models.

10BASE-TX ports

10/100BASE-TX ports

100BASE-FX ports

Console connection

Reset button

Basic Connections

For communications to take place between two devices, the transmitter of one device must connect to the receiver of the other device. The connection must be achieved through a crossover function, which could be a crossover cable or a port that implements the crossover function internally. All the 10/100BASE-TX ports are wired for MDI-X (media-dependent interface-crossover). Use the proper cabling to connect to devices as follows:

To connect to a switch, hub, or bridge, use a crossover cable.

To connect to a workstation or file server, use a straight-thru cable.

Autonegotiation on the 10/100BASE-TX ports is set by polling the connected device. The two devices will negotiate the speed, 10 Mbps or 100 Mbps, and select whichever is most optimal.
