Aitech C690

Marvell® Prestera® 98DX4122 Controller, Layer 2 and Layer 3 Management

Manufacturer: Aitech
Aitech C690

Aitech’s C690 is a high-performance 3U VPX integrated managed Gigabit Ethernet and PCI Express Switch for embedded and harsh environment applications. Managed switching of up to eight Gigabit Ethernet ports is performed by the Marvell® Prestera® 98DX4122 Gigabit Ethernet Switch Controller and Marvell’s Routing OS.

An embedded web server provides a convenient and intuitive graphical switch management interface via a web browser. Command-line switch management is also supported over network and RS-232 connections.
