Description

The twisted-pair port on the switch can operated in either half- or full-duplex mode. You can set the duplex mode manually or allow the switch to set it automatically through Auto-Negotiation. With Auto-Negotiation, if the end- node is capable of full-duplex mode, the twisted-pair port is set automatically to full-duplex mode. If the end-node is capable of half-duplex mode, the port is set automatically to half-duplex mode.

Auto MDI/MDI-X

An RJ-45 twisted-pair port on a 10 Mbps or 100 Mbps Ethernet network device can have one of two possible wiring configurations: MDI or MDI-X. The RJ-45 port on a PC, router, or bridge is typically wired as MDI, while the twisted-pair port on a switch or hub is usually MDI-X.

To connect two 10 Mbps or 100 Mbps network devices together that have dissimilar port wiring configurations, such as MDI to MDI-X, use a straight- through twisted-pair cable. To connect two network devices that have the same wiring configuration, such as MDI to MDI, use a crossover cable.

The AT-FS20x switches feature automatic MDI/MDI-X. The RJ-45 port automatically determines the configuration of the port on the device to which it is connected and then configures itself appropriately. For example, if a port on a switch is connected to a port on a bridge, which is typically wired as MDI, the port on the switch automatically configures itself as MDI-X. This feature allows you to use either crossover cables or straight-through cables when connecting a device to the twisted-pair port.

Fiber Optic Port

The AT-FS20x switches have one 100Base-FX fiber optic port. The fiber optic port features either an SC or ST connector.

Port Speed

The fiber optic port is compliant with the 100Base-FX standard and has a fixed operating speed of 100 Mbps. The end-node connected to the fiber optic port on the switch must also be able to operate at 100 Mbps.

Duplex Mode

The fiber optic port on the switch can operate in half- or full-duplex mode. You must set the duplex mode manually using the DIP switches on the back of the unit.
