Enables a new generation of lower-cost switches with Gigabit
Ethernet connectivity and much smaller form factors.
Uses field-proven industry-standard Gigabit Ethernet SerDes
which lowers overall system interoperability and reliability
risks.
Provides the most cost-effective Gigabit Ethernet connectivity
to the desktop and control plane for all remote, branch, and
Enterprise needs.
802.1Q tag VLAN, trunking, and 802.1p priority enables the
switch to be designed into a wide variety of applications from
unmanaged to websmart to managed switch.
Jumbo frame support allows the device to be connected to
corporate server farms and networks while maintaining
maximum TCP/IP performance.
CPUs are not required to initialize and run in cost-sensitive
unmanaged applications, providing true plug-and-play
connectivity.
Suitable for fully managed applications due to support for
Spanning Tree and integration of full MIB counters
SGMII interfaces ensure superior EMI performance and
lowest possible number of required board layers while
enabling connections to industry-standard physical layer
devices (e.g., BCM5464R)
Lowest possible system cost through minimized number of
external components.
Higher system reliability and noise reduction due to
elimination of component with lowest MTBF (the fan).
