The  DFE-551FX  Optical  Fiber  Fast  Ethernet  Adapter connects  your  desktop  PC  to  a  reliable  fber  network. The  card  plugs  into  a  PCI  expansion  slot  inside  your PC,  transmits  data  at  200Mbps  full  duplex.  Supporting advanced functions including traffc priority queues and VLAN, this adapter provides a secure environment to let you  run bandwidth-demanding applications, such as  IP
telephony and video conferencing.

Reliable Fiber Connection
The  DFE-551FX  card  allows  you  to  establish  secure fber  link  for your PC.  It can be used  to set up a power workstation or a server with a direct fber connection to a Fast Ethernet switch. Capable of running at 200Mbps full-duplex, this card serves well in a high electro-magnetic interference environment, providing a cable distance of up to 2 km to the switch.

Wake-On-LAN Power Management
The  card  supports  Advanced  Confguration  Power Interface  (ACPI)  Wake-On-LAN  (WOL),  allows  your computer  to  be  powered  ON/OFF  from  a  remote  place. Providing a great utility for power management of the PC, this  function allows  the administrator  to send a wake-up signal to the computer to initiate action at irregular times and from distant locations.

High Performance
With 32-bit bus master operation, the card guarantees the highest  performance.  Bus master  transfers  data  directly between  the  card  and  the  host  at  multi-megabits  per second, bypass the host CPU to alleviate its workload.

Flow Control to Minimize Packet Loss
The  card’s  embedded  fow  control  provides  a means  to protect against possible data loss during transmission on the network. When connected  to a Fast Ethernet switch that supports fow 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.

VLAN to Improve Performance and Security
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  traffc. The card provides a VLAN table for the following functions: fltering packets by recognizing VLAN Tags, stripping VLAN
Tags on receive, and inserting VLAN Tags on transmit.

IEEE 802.1p Priority Queues Support
With packet prioritization capability, the card allows traffc to be queued as critical and non-critical, permitting your computer  to  run  voice  over  IP,  video-conference  and multimedia  applications where  packets  are  delivered  at best-effort speeds.

RPL and PXE Remote Boot Optionst
2  remote  boot  options  are  available  for  selection. Administrators can choose  to  set up a  security  scheme for diskless workstations  to boot  from  servers using  the traditional  Remote  Program  Load  (RPL)  or  Intel’s  Pre-boot  Execution  Environment  (PXE).  Stations  with  boot ROMs  installed  on  the  on-board  socket  can  boot  O.S. from NetWare, NT and other servers  to  run applications designated by the administrator.
