DQS-5000-56ZSNew
48-port 25G SFP28, 8-port 40/100G QSFP28 L3 managed switch with 2 AC PSUs and 5 front-to-back fan modules
Description
The DQS-5000-56ZS is a high-performance 25G/100G switch platform designed specifically for micro data center environments. With 48 x 25G SFP28 ports and 8 x 100G QSFP28 uplink ports, it delivers powerful Layer 2 and Layer 3 capabilities in a compact 1RU form factor. Pre-loaded with ONIE and optimized for SONiC OS, this switch is ideal for disaggregated edge-scale cloud, enterprise micro-sites, and containerized workloads where agility, openness, and density are key. The system combines open software flexibility with carrier-class hardware resiliency, bridging the gap between traditional network performance and the evolving needs of modern micro infrastructures.
Compact and Powerful for Edge Deployments
The DQS-5000-56ZS delivers up to 2.0 Tbps (4.0 Tbps full duplex) of non-blocking switching capacity with 48 x 25 Gbps SFP28 and 8 x 100Gbps ports in a compact 1RU, 19-inch rack-mount design. Front-to-back airflow, 2 (1+1) hot-swappable redundant PSUs, and 5 (N+1) hot-swappable fans ensure high reliability and thermal efficiency — ideal for space- and power-constrained micro data centers.
SONiC OS-Ready with ONIE Pre-Installed
Pre-loaded with the Open Network Install Environment (ONIE), the switch supports quick deployment of open network operating systems such as SONiC OS. It enables a fully disaggregated, modular architecture with advanced features including BGP, EVPN, VXLAN, VRF, and MC-LAG — providing hyperscale scalability at the micro data center edge.
Open and Automatable Management
Compatible with Open Network Linux (ONL) and industry-standard CLI, the switch supports DevOps-friendly operations. Integration with automation frameworks and programmable interfaces simplifies network management, improves visibility, and enhances operational efficiency in micro data center environments.
