D-Link DGE-550T REV-A3

D-Link DGE-550T REV-A3 DL-2000 - 32-64-Bit PCI Bus Copper RJ45 Gigabit Ethernet adapter

Key Features
Gigabit Sever
Card
Twisted-pair Copper Gigabit Server Card
The DGE-550T Gigabit PCI card is a high-bandwidth network adapter designed for server connection over the inexpensive
twisted-pair copper wires. At 2000Mbps full-duplex speed, this card pr
ovides very high dedicated bandwidth capacity for
power servers directly attached to Gigabit switches. With advanced functions like VLAN, Flow Contr
ol, Traffic Prioritization
and others, this Gigabit card brings you a high level of performance and security, allowing you to run bandwidth-intensive
applications like multimedia, video conference and IP telephony.
Gigabit Over Twisted-pair
High Performance
Flow Control for Secure Transmission
The DGE-550T offers an inexpensive alternative solution
to fiber-optic Gigabit. Using your existing low-cost Cat. 5
copper twisted-pair wires as the transmission media, this
card allows you to instantly upgrade your departmental
servers to Gigabit capability without having to install new,
expensive fiber cables.
Using the bus master mode with direct DMA paths, the
DGE-550T provides high throughput between the server
host and the card, bypass the host's memory buffer. The
card operates in 32-bit 33MHz PCI bus as well as in the
upcoming 64-bit 66MHz PCI bus, auto-configuring
according to the different data path widths to guarantee
compatibility with various server configurations. To
enhance performance, the card provides large,independent
receive/transmit FIFO, jumbo frame support and adaptive
Inter-Frame Spacing (IFS) capacity.
With IEEE 802.3x flow control support, your server is
protected against possible data loss during transmission on
the network. Connected to a Gigabit switch that supports
flow control, the card receives signals from the switch
regarding buffer overrun during peak usage periods. When
the switch signals a buffer run situation, the card delays
transmission until the switch is ready again to accept new
data.
Priority Queues
VLAN to Improve Performance and Security
Easy Migration Through 10/100/1000Mbps
Support
This function allows your server to run V
oice over IP
(V
oIP) telephony, video-conference and other multimedia
applications where traffice is queued as critical and non-
critical, and network packets are delivered at best-effort
speeds.
The card supports IEEE 802.1Q multiple Virtual LAN,
allowing you to segment the network to smaller domains
to improve performance and security. Dissemination of
broadcast and unnecessary computer-to-computer packets
can be restricted to reduce extraneous traffic. The card
provides a VLAN table for the following functions:
filtering packets by recognizing VLAN Tags, stripping
VLAN Tags on receive, and inserting VLAN T
ags on
transmit.
The card supports three network speeds, 10Mbps,
100Mbps and 1000Mbps, allowing you to run in Fast
Ethernet now, and migrate to Gigabit anytime later without
having to change neither network adapters nor network
cables. The card auto-senses and auto-negotiates to use
the best network speed. Full/half duplex is supported for
10Mbps and 100Mbps, while full duplex is supported for
the Gigabit speed.

The DGE-550T Gigabit
PCI card for
server connection. This
card connects to the
Cat. 5 twisted-pair cable,
common at most
network sites, to
transfer data at
a blazing 2000Mbps
