Layer 3 48-Port 25G SFP28 + 8-Port 100G/40G QSFP28 Managed Data Center Switch

» DCS-7342-48Y8C

PLANET is proud to announce the launch of the DCS-7342-48Y8C Version 2. While retaining the industry-leading high-density configuration of 48-port 25GbE SFP28 and 8-port 100GbE QSFP28 interfaces, DCS-7342-48Y8C Version 2 is built upon a radically updated hardware architecture designed to overcome the physical limitations of the first-generation platform.

This architectural evolution significantly expands system capacity and provides the flexibility required for future-scale network expansions.
