Product Summary

The VSC7389XHO is a 16-Port Integrated Layer-2 Gigabit Ethernet Smart Switch with Transceivers. It is specifically targeted at SMB, SME, and SOHO unmanaged applications, and with its on-chip V-Core CPU and parallel CPU interface, it enables web-managed and managed switch applications. Being a member of the SparX switch family provides a number of unique advantages when designing with the VSC7389XHO, including software compatibility between members. Software written for SparX-G16 can therefore easily be ported from or used with other switch configurations in the family, and vice-versa. The applications of the VSC7389XHO include 16-Port Unmanaged Gigabit Ethernet SMB/SME/SOHO Switch and 16-Port Web-Managed Smart Gigabit Ethernet SMB/SME/SOHO Switch.
