(“D-Link”) provides this limited warranty for its product only to the person or entity who originally purchased the product from D-Link or its authorized reseller or distributor. Limited Hardware Warranty: D-Link warrants that the hardware portion of the D-Link products described below (“Hardware”) will be free from material defects in workmanship and materials from the date of original retail purchase of the Hardware, for the period set forth below applicable to the product type (“Warranty Period”) if the Hardware is used and serviced in accordance with applicable documentation; provided that a completed Registration Card is returned to an Authorized D-Link Service Office within ninety (90) days after the date of original retail purchase of the Hardware. [. . . ] Among them, 100BASE-T (Fast Ethernet) provides a nondisruptive, smooth evolution from the current 10BASE-T technology. The non-disruptive and smooth evolution nature, and the dominating potential market base, virtually guarantee cost effective and high performance Fast Ethernet solutions in the years to come. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade path and takes advantage of the existing investment in hardware, software, and personnel training. 1 Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol. it transmits packets among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network bandwidth available to users on a local area network. A switch divides a local area network into multiple, separate segments. Each segment has it’s own full Ethernet or Fast Ethernet bandwidth that doesn’t compete with the other segments for network transmission. The switch acts as a high-speed selective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another and blocks traffic that does not need to be transmitted. By doing this the total network bandwidth is multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet networks, a switch is an effective way of eliminating the problem of chaining hubs beyond the “tworepeater limit. € A switch can be used to split parts of the network into different collision domains, making it possible to expand a Fast Ethernet network beyond the 205-meter network diameter limit. This allows for auto-sensing of speed (10/100Mbps) thereby providing you with automatic and flexible solutions in your network connections. This minimizes dropped packets by sending out collision signals when the port’s receiving buffer is full. Unpacking Open the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items: One DSS-5+ 5-port 10/100Mbps Dual Speed Ethernet Switch One external power adapter This User’s Guide If any item is found missing or damaged, please contact your local reseller for replacement. Setup The setup of DSS-5+ can be performed using the following steps: The surface must support at least 1. Visually inspect the DC power jack and make sure that it is fully secured to the power adapter. Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. [. . . ] ) via a two-pair Category 3 , 4 , 5 UTP/STP straight or crossover cable. Using straight cable When using straight cable, this is done from the uplink (MDI-II) port of the Switch (Switch A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other switch (switch B) or other devices. Using crossover cable When using crossover cable, this is done from any (MDI-X) port of the Switch (Switch A) to any of the 10Mbps, 100Mbps (MDI-X) port of the other switch (switch B) or other devices. The “100LINK/ACT, 10LINK/ACT” LED indicator light green for hookup to 100Mbps speed or light amber for hookup to 10Mbps speed. [. . . ]
