The DFE-550FX is a 100Base-FX Multimode fiber
based network card supporting transfer speeds of up to
200Mbps in full duplex mode and cable distances up
to 2km. It can be used in either workstations or servers
and supports advanced features such as WOL (Wake-
on-LAN management), 802.3x Flow control, 802.1Q
VLAN support, and 802.1p priority tagging.
High Performance
With 32-bit bus master operation, the DFE-550FX
guarantees the highest level of performance. Bus
mastering guarantees data is passed directly between
the card and the host bypassing the host CPU and
reducing added workload and CPU overhead. This in
turn improves network and host performance.
Wake-on-LAN Power Management
The DFE-550FX supports Advanced Configuration
Power Interface (ACPI) Wake-On-LAN (WOL), which
allows your computer to be powered ON/OFF from a
remote location. Providing a great utility for power
management, this function allows the administrator
to send a ‘wake-up’ signal to a computer or server to
initiate a power-up sequence.
802.3x Flow Control to Minimize Packet Loss
The DFE-550FX supports 802.3x flow control. This
provides a means to protect against possible data loss
during transmission on the network. When connected
to a Fast Ethernet switch that also supports 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.
802.1Q VLAN to Improve Performance and Security
The DFE-550FX supports IEEE 802.1Q VLAN tagging,
allowing you to segment the network into smaller
domains to improve performance and security. The
DFE-550FX provides a VLAN table for the following
functions: filtering packets by recognizing VLAN
Tags, stripping VLAN Tags on receive, and inserting
VLAN Tags on transmit.
