Introduction Congratulations on your purchase of the DES-1026G 24-Port 10/100Mbps + 2-Port 10/100/1000Mbps Gigabit Ethernet Switch.
extension of the 10BaseT Ethernet standard, designed to raise the data transmission capacity of 10BaseT from 10Mbits/sec to 100Mbits/sec. An important technology incorporated by 100BaseT is its use of the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol which is the same protocol that 10BaseT uses - because of its ability to work with several different types of cable, including basic twisted-pair wiring.
For Fast Ethernet networks, a switch is an effective way of eliminating the problem of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, 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.
LEDs LED stands for Light-Emitting Diode. The front panel LEDs provides instant status feedback and simplifies monitoring and troubleshooting tasks. LED indicators of the Switch POWER On When the Power LED light is on, the Switch is receiving power. Off When the Power LED light is off , the power cord is improperly connected. Ports 1-24 Status LEDs LINK/ACT On When the LED light is on, the respective port is connected to the 10/100Mbps Ethernet network.
transferring or receiving data on a 10/100/1000Mbps Ethernet network. Off No link. 1000Mbps On When the LED lights on, the respective port is connected to a Gigabit Ethernet network. Off The respective port is connected to a 10/100Mbps Ethernet network, or no link. 100Mbps On When the LED lights on, the respective port is connected to a 100Mbps Fast Ethernet network. Off When the LED light is off, the respective port is connected to a 10Mbps or Gigabit Ethernet network or there is no link.
1000BASE-T Twisted Pair Ports (Port 25~26) The DES-1026G is equipped with two Gigabit twisted pair ports that are auto negotiable 10/100/1000Mbps and also support auto MDI/MDIX crossover detection. These two ports can operate in half- and full- duplex modes. Rear Panel Power Switch Power Connector AC Power Connector This is a three-pronged connector that supports the power cord. Plug in the female connector of the provided power cord into this connector, and the male into a power outlet.
Leave at least 10cm (about 4 inches) of space at the front and rear of the hub for ventilation. Install the DES-1026G on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protects the hub case from scratching.
Mount the Switch in the rack Connecting Network Cable The DES-1026G supports 10/100/1000Mbps Gigabit Ethernet. It runs full/half duplex transfer mode for 10/100Mbps and full duplex transfer mode for 1000Mbps. Each port on the DES-1026G supports AutoMDI/MDI-X. Auto-MDI/MDI-X is a feature that eliminates the need for worrying about using either a standard or crossover cable—you can use either one—and allows any port to be an uplink port.
