Aitech C681 - 3U VPX Gigabit Unmanaged Ethernet Switch

Up to 24 Fast/Gigabit Ethernet Ports, Transition Module Option

Introduction

Aitech’s C681 is a high-performance 3U VPX Unmanaged Gigabit Ethernet Switch for embedded and harsh environment applications.

Gigabit Ethernet switching is performed by the Marvell Prestera® 98DX106. The switch is unmanaged and does not require any user configuration.

The C681 provides up to ten Ethernet ports, each of which is factory configured as 1000Base-T or 1000Base-BX/KX.
