The D-Link DGE-528T is a high-performance 10/100/1000Mbps copper Gigabit PCI card for desktop PC. Capable of running at full-duplex Gigabit speed, this card gives your PC 2000Mbps data transmission on your existing Cat. 5 twisted-pair network cable. As an inexpensive alternative solution to fiber-optic, the card allows you to instantly upgrade to Gigabit without requiring you to install new, expensive fiber cables. The card supports 10/100/1000Mbps network speed auto-sensing and full/half duplex auto-negotiation. The card provides on-board screening of VLANs Tagged Ethernet frames, allowing your PC to be configured with VLAN-supported switch. Your PC can be part of a VLAN network, where domains are segmented up to enhance performance and security. Wake-On-LAN (WOL) is an Advanced Configuration Power Interface (ACPI) function allowing a powered OFF computer to be powered ON from a remote station. This function allows the administrator to send wake-up signals to a computer. The WOL function provides a great utility for power management of the PC and allows users to initiate action at irregular times and from distant locations. The card\'s embedded flow control and independent FIFO provide a means to protect against possible data loss during transmission on the network. When connected to a Gigabit switch supporting flow control, the card receives signals from the switch regarding buffer overrun during peak usage periods. The card then delays transmission until the switch is ready again to accept new data. Using a single chip solution, this card is very small in size and consumes very little power of your computer system.
