PRODUCT BRIEF
VSC7442
52-Port L2/L3 Enterprise and Industrial Ethernet
Switch
Vitesse’s next generation switch family delivers a flexible
Enterprise and Industrial Ethernet solution.
The VSC7442 SparX-IV-52™ device is a 52 Gbps SMB/SME Industrial
Ethernet switch with up to 52 Gigabit Ethernet (GbE) ports.
The device provides a rich set of Enterprise Ethernet switching features.
Using multistage Vitesse 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, VSC7442 integrates VeriTime™, Vitesse’s
patent-pending distributed timing technology that delivers the industry’s
most accurate IEEE 1588v2 timing implementation.
Highlights
• Single-chip 52 Gbps switching
solution
• Fully managed L2 switching and L3
forwarding features
• Industrial temperature range
• Easy upgrade within SparX-IV
family to higher bandwidths
including 10 GbE port support
Applications
• Fully managed L2/L3 switch
• Industrial Ethernet switch
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.
