The DGE-560SX Fiber Gigabit PCI Express x 4 Adapter is a high-performance network card that lets businesses take advantage of the PCI Express (PCIe) slots of their servers to enhance network performance with fiber-optic connectivity. The PCIe architecture ensures dedicated input/output (I/O) bandwidth for the adapter, ensuring high performance without bus sharing for Gigabit Ethernet connectivity in fiber-optic networks. With fiber optic cable, distance can reach up to 550m & network speed 2000 Mbps (full-duplex). The DGE-560SX supports 2 Gbps transfer rate between the adapters board & the server host. As a successor to the PCI & PCI-X interfaces, the PCI Express serial bus eliminates many of the inefficiencies of parallel PCI & PCI-X architectures. With lower pin counts & lower power consumption requirements, the DGE-560SX adapter also reduces system power requirements. PCI Express is backward compatible with PCI & PCI-X addressing, which allows all existing applications & Operating Systems to function unchanged. The DGE-560SX adapter provides on-board screening of VLAN tagged Ethernet frames compliant with IEEE 802.1Q. This allows the server to operate in a flexible & secure network configuration in a standards-based environment. The adapter supports 802.1p Priority Queues for enhanced delivery of delay-sensitive data such as voice & video. The DGE-560SX supports other advanced features such as Jumbo frames of up to 9KB & Promiscuous mode. It supports ACPI (Advanced Configuration & Power Interface) specifications to enable OS-directed configuration & Power Management (OSPM) to enumerate & configure server motherboards. The adapter supports SNMP agent for management under an SNMP-based platform. It is often difficult or impossible to schedule downtime on a server to replace or install peripheral cards. As a PCI Express card, the DGE-560SX provides native support for hot plugging & hot swapping, which makes it absolutely ideal for installation in a server. This hot swap capability makes it easy for network administrators to add, change or remove I/O peripherals while minimizing the server downtime.
