10/100 Fast Ethernet Switch User’s Guide

10 (& 100Mbps) Mode Operations: Port 1

This port requires Category 3, 4, or 5 unshielded twisted-pair or shielded twisted-pair (UTP/STP) cable, a thin Ethernet coaxial cable with a T- connector, or an AUI adapter module for a thick Ethernet or Fiber optic connection. Port 1 can be used to connect to any 10BASE-T hub or other device using any of the listed media, or to any 100BASE-TX device via the twisted-pair port. The attached device must be within 100 meters of the 10/100 Fast Ethernet Switch. A crossover-type cable must be used for the connection unless connecting to an uplink capable switch or hub.

10/100Mbps Mode Operations: Port 2

This port requires a Category 3, 4, or 5 unshielded twisted-pair or shielded twisted-pair (UTP/STP) cable. The attached device must be within 100 meters of the 10/100 Fast Ethernet Switch. A crossover-type cable must be used for the connection unless connecting to an uplink capable switch or hub.

Setting the Duplex Mode

Both twisted-pair ports of the device can be set for half-duplex or full-duplex operation (the BNC and AUI ports are half-duplex only). At half-duplex operation, packet transmission and reception do not occur simultaneously, thus communication speed is limited to 10 or 100Mbps using either port. During full-duplex operation, packet transmission and reception occur simultaneously, thus communication speed is doubled to 20 or 200Mbps using either port. Full-duplex operation can be used on links between the 10/100 Fast Ethernet Switch and any hub, switch, or other device that supports full-duplex operation.

DES-802 specifications

The D-Link DES-802 is a versatile and efficient networking switch designed for small to medium-sized businesses. With its user-friendly features and robust design, it provides an ideal solution for enhancing network performance and reliability. The key highlight of the DES-802 is its 8-port configuration, making it suitable for connecting multiple devices such as computers, printers, and servers within a local area network (LAN).

One of the main features of the D-Link DES-802 is its support for auto-negotiation, allowing coherent communication between devices regardless of their speed and duplex configuration. This capability ensures seamless integration and minimizes compatibility issues, enabling businesses to expand their networks without the need for extensive reconfiguration.

Equipped with Ethernet ports, the DES-802 supports data rates of up to 1 Gbps, providing high-speed connections essential for modern applications that demand substantial bandwidth. Additionally, the switch employs link aggregation, allowing for increased throughput and redundancy by combining multiple links into a singular logical connection.

Power over Ethernet (PoE) capabilities is another significant characteristic of the D-Link DES-802. This feature enables the switch to deliver power directly to connected devices, such as VoIP phones and wireless access points, through the data cable, simplifying installations and reducing the need for additional wiring and outlets.

From a management perspective, the DES-802 features a web-based management interface, providing administrators with a straightforward approach to configure and monitor network settings. It facilitates network control through features such as VLAN support, which enhances security and performance by segmenting networks into distinct virtual LANs.

In terms of reliability, the DES-802 incorporates redundant power supply options, ensuring continuous network operation even in the event of power failure. The switch is built with durability in mind, featuring a metal chassis that withstands varying environmental conditions while maintaining performance.

Overall, the D-Link DES-802 stands out for its blend of advanced features, such as auto-negotiation, high-speed connectivity, PoE capability, and robust management options, making it a reliable choice for businesses looking to optimize their network infrastructure efficiently.
