2. Introduction
2.1 Description
The Two-Port 10/100 Ethernet Switches are standalone, dual-port Ethernet-
to-Fast-Ethernet switches. In addition to enabling 10/100-Mbps and 100/100-
Mbps switching, the Switches can also extend the diameter of Fast Ethernet
networks up to 100 km.
The Two-Port 10/100 Ethernet Switch is available in both a UTP and a
fiberoptic version. Each copper port on the Two-Port 10/100 Ethernet Switch
offers IEEE standard NWay auto-negotiation and is configurable for either
half-duplex (for a 100-Mbps shared connection) or full-duplex (for a 200-
Mbps point-to-point collision-free connection). Each fiber port is
configurable for only a 100-Mbps half-/full-duplex connection.
The Two-Port 10/100 Ethernet Switch uses self-learning of network addresses,
and filters local traffic, collisions and error packets.
2.2 Features
• Complies with IEEE 802.3 and IEEE 802.3u standards.
• Uses UTP, multimode, or single-mode DSC connectors.
• Up to 110 km over single-mode fiber.
• Full-/half-duplex operation on all ports and speeds.
• NWay auto-negotiation for automatic speed and duplex configuration
(UTP only).
• Plug-and-play installation and support for all network operating systems
and protocols.
• Status LEDs indicate switch operations for easy maintenance.
