The Juniper Networks QFX10002-72Q Data Center Switch is a high-density, fixed-configuration switching platform engineered for data center spine, core, and service provider environments. With a compact 2RU form factor, this switch delivers exceptional performance, scalability, and flexibility, making it an ideal alternative to larger modular chassis systems.
Equipped with 72 × 40GbE QSFP+ ports, the QFX10002-72Q provides high-density connectivity for modern data center fabrics. It also supports conversion of up to 24 ports to 100GbE QSFP28, enabling seamless migration to higher speeds while preserving existing infrastructure investments. Additionally, breakout capabilities allow ports to operate at 10GbE, offering unmatched flexibility for mixed-speed deployments.
Powered by Juniper’s advanced Q5 ASIC, the switch features 4 GB of deep packet buffering using Hybrid Memory Cube (HMC) technology, ensuring reliable performance during traffic bursts and congestion. With a switching capacity of up to 5.76 Tbps and a forwarding rate of 2 Bpps, it delivers consistent wire-speed performance for data-intensive workloads.
The QFX10002-72Q is fully optimized for modern network architectures, supporting EVPN-VXLAN for scalable Layer 2 and Layer 3 overlays, along with advanced routing protocols such as BGP, OSPF, and IS-IS. Its ability to handle large-scale routing tables (up to 1 million IPv4 routes) makes it suitable for Internet-scale peering, cloud networking, and hyperscale data center deployments.
For environments requiring precise timing, the switch includes Precision Time Protocol (PTP) support, making it ideal for applications such as financial trading, media streaming, and real-time analytics.
Designed for reliability, the QFX10002-72Q includes redundant hot-swappable power supplies and fan trays, ensuring continuous operation in mission-critical environments. Fully integrated with Junos OS and compatible with automation tools like Python, Ansible, Puppet, and Chef, it enables streamlined network management and orchestration.
With its combination of high port density, deep buffering, flexible speed support, and carrier-grade reliability, the Juniper QFX10002-72Q is a powerful and future-ready solution for next-generation data center networks.

FAQs:
Q1. How do I convert the ports to 100GbE?
The QFX10002-72Q is designed so that every third port (up to 24 total) can be configured to run as a 100GbE QSFP28 port. When a port is used for 100GbE, the adjacent ports are disabled to maintain the aggregate throughput.
Q2. Can I use 10GbE breakout cables on this switch?
Yes. All 72 ports can be broken out into 4x10GbE interfaces using QSFP+ to SFP+ breakout cables, providing a maximum density of 288 x 10GbE ports.
Q3. Does this switch support Junos Fusion?
Yes. The QFX10002-72Q can act as an aggregation device in a Junos Fusion fabric, managing multiple satellite devices as a single logical entity.
Q4. Is the airflow reversible?
No. The QFX10002 series is typically designed for front-to-back airflow (Airflow Out). You must ensure your data center cooling matches this pattern.
Q5. What is the power requirement for a fully loaded 72Q?
Typical power consumption is approximately 530W, but this varies based on the type of optics used (SR4 vs. LR4) and the traffic load.
