User manual D-LINK DES-1024D

[. . . ] Describes the front panel, rear panel and LED indicators of the Switch. Lists the technical (general, physical and environmental, and performance) specifications of the Switch. 1 I NTRODUCTION This chapter describes the features of the DES-1024D and some background information about Ethernet/Fast Ethernet switching technology. [. . . ] If segmented correctly, most network traffic will remain within a single segment, enjoying the full-line speed bandwidth of that segment. Switches provide full-line speed, dedicated to bandwidth for all connections. This is in contrast to the hubs, which use the traditional shared networking topology, where the connected nodes contend for the same network bandwidth. When two switching nodes are communicating, they are connected with a dedicated channel between them, so there is no contention for network bandwidth with other nodes. As a result, the switch reduces considerably the likelihood of traffic congestion. 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 the existing 10Mbps networks and the new 100Mbps networks. Switching LAN technology is a marked improvement over the previous 3 generation of network hubs and 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. Features The DES-1024D is a high-performance switch designed specifically for environments where traffic on the network and the number of users increase continuously. 24-port 10/100BASE Ethernet Switch with RJ-45 connectors Supports Auto-negotiation of speed and duplex modes for each port Supports Auto-MDI/MDI-X on each port, eliminating the need for cross over cables or uplink ports Wire-speed reception and transmission Store-and-Forward switching method Integrated address Look-Up Engine, supports 8K MAC addresses Supports 2. 5Mbits RAM for data buffering Front-panel diagnostic LEDs Broadcast storm protection IEEE 802. 3x flow control for full-duplex Back pressure flow control for half-duplex 4 U NPACKI NG AND S ETUP Unpacking Open the shipping cartons of the DES-1024D and carefully unpack its contents.

[. . . ] Link / Activity This green LED indicator illuminates when the port is connected to a Fast Ethernet or Ethernet station; the indicator blinks when transmitting or receiving data. 8 100Mbps (green) This green LED indicator illuminates when the port is connected to a 100Mbps Fast Ethernet station. The LED does not illuminate when the port is connected to 10Mbps Ethernet station. [. . . ]
