  • Page 7: Introduction

    INTRODUCTION This chapter describes the features of the DGS-1248T Web Smart 48-Port 10/100/1000Mbps Gigabit Switch and some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same...

  • Page 8: Fast Ethernet Technology

    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 dividing a local area network into different segments, which do not compete with each other for network transmission capacity.

  • Page 9: Vlan (Virtual Local Area Network)

    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, the setup, and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems.

    Leave at least 10cm of space at the front and rear of the hub for ventilation. Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the...

  • Page 12: Rack Mounting

    The Switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the Switch’s front panel (one on each side), and secure them with the provided screws.

  • Page 13: Connecting Network Cable

    The Switch uses the AC power supply 100-240V AC, 50-60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The Switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.

  • Page 14: Identifying External Components

    (see the LED Indicators chapter below). 1000BASE-T Twisted Pair Ports (Port 1~48) The DGS-1248T is equipped with fourty-eight Gigabit twisted pair ports that are auto negotiable 10/100/1000Mbps and also support auto MDI/MDIX crossover detection. These ports can operate in half- and full-duplex modes.
