Product Overview

The Juniper QFX5240-64QD-CHAS is a high-performance 2U fixed-configuration switch from the QFX Series, designed for data center spine-and-leaf deployments. It features 64 QSFP56-DD ports supporting up to 800GbE interfaces and 2 10-Gbps SFP+ ports, delivering 51.2 Tbps of unidirectional throughput. Ideal for AI/ML fabrics, cloud-scale networking, and high-density 400G/800G environments, it runs Junos OS Evolved for advanced automation and programmability.

Architecture & Performance

Powered by an Intel 4-core 2.2-GHz Ice Lake CPU with 32 GB DRAM and 960 GB SSD storage. Key metrics include 51.2 Tbps throughput, 136K MAC addresses, 2M IPv4/IPv6 unicast routes, 165 MB packet buffer, and 8 unicast/2 multicast QoS queues per port. Supports 1+1 redundant power and hot-swappable fans with front-to-back airflow.

Port & Management Details

Network ports: 64x QSFP56-DD (up to 800G), 2x SFP+. Management: 1x RJ-45 console, 1x RJ-45 OOB management, 1x USB Type A. Timing: 10 MHz, PPS, ToD ports. Form factor: 2U (3.46 x 17.26 x 25.51 in, 48.5 lb).
