VSC7444
26-Port L2/L3 Enterprise Gigabit Ethernet Switch with 10 Gbps Links
Microsemi’s next generation switch family delivers a flexible Enterprise
and Industrial Ethernet solution.
The VSC7444 SparX-IV-44™ device is an SMB/SME Industrial Ethernet
switch with up to 26 ports supporting a combination of 1G, 2.5G, and
10G Ethernet ports.
The device provides a rich set of Enterprise Ethernet switching features.
Using multistage Versatile TCAM technology (VCAP™), it delivers VLAN
and QoS processing that enables delivery of differentiated services,
security through intelligent frame processing, and egress frame
manipulation.
For industrial applications, VSC7444 integrates VeriTime™, Microsemi’s
patent-pending distributed timing technology that delivers the industry’s
most accurate IEEE 1588v2 timing implementation.
A powerful 500 MHz CPU enables full management of a Layer 2 and
Layer 3 Ethernet switch solution.
A comprehensive application programming interface (API) and software
development package accelerates time-to-market for managed Ethernet
applications. The software API package integrates easily with third-party
software, preserving existing software investments.
