INTRODUCTION

This section describes the features of the Switch, as well as giving some background information about Fast Ethernet, Gigabit Ethernet, and switching technology.

Fast Ethernet Technology

The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve client/server response times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution from 10BASE-T technology.

100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment in hardware, software, and trained personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnetworks.

Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NICs are able to perform 10 times the number of operations in the same amount of time.

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow's rapidly improving switching and routing internetworking technologies.

Switching Technology

Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or fast Ethernet LAN segments.

Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by making it possible for a local area network to be divided into different segments which don't compete with each other for network transmission capacity, giving a decreased load on each.

The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the switch, without interfering with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks.

Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and maintenance required make routers relatively impractical. Today's switches are an ideal solution to most kinds of local area network congestion problems.

DGS-1024T Gigabit Ethernet Switch

General Description of Switch

The D-Link's new unmanaged the DGS-1024T provides 22 1000BASE-T copper ports and 2 Combo (1000BASE-T/Mini-GBIC) ports. Each all-gigabit-port switch is designed for backbone and server connection with department and enterprise networks. Powerful and versatile, they eliminate network bottlenecks while giving users the capability to fine-tune performance.

As Layer 2 switches, all ports of the DGS-1024T provide wire-speed switching by hardware-based ASIC. With a height of 1U and a standard rack-mount size, the switches are especially suitable for a departmental environment. Clear, at-a-glance per-device/per-port LED indicators make it easy for users to understand and control network status.

Each of the unmanaged stand-alone switches is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10/100/1000 Mbps bandwidth. DGS-1024T has 22 1000BASE-T copper ports and 2 Combo (1000BASE-T/Mini GBIC) ports. These ports can be used for connecting network backbones, PCs, and servers. The copper ports use standard twisted-pair cabling, while the two mini-GBIC ports use fiber optic cabling.

CONNECTING THE SWITCH

This chapter describes how to connect the Switch to your Gigabit Ethernet network.

Switch to End Node

End nodes include PCs outfitted with a 10, 100 or 10/100 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface Card (NIC) and most routers.

An end node can be connected to the Switch via a two-pair Category 3, 4, 5, or 5e UTP/STP cable—for optimal performance, Category 5e is recommended. The end node should be connected to any of the ports of the Switch.

Figure 4-1. Switch connected to an end node

The Link/Act LEDs on the bottom row of the front panel of the device light green when the link is valid. The LED on the top row indicates port speed. It will light solid green for 1000 Mbps connections, solid amber for 100 Mbps connections, and will remain off for 10 Mbps connections. A blinking green LED on the bottom row indicates packet activity on that port.

Switch to Network Backbone or Server

The two mini GBIC ports on the DGS-1024T are ideal for uplinking to a network backbone or network server. These ports operate at 1000 Mbps in full-duplex mode.

Connections to the mini GBIC ports are made using fiber optic cable, depending on the type of port. A valid connection is indicated when the Link LED is lit.
