Description

The QFX5140 Data Centre Switch delivers ultra-high-density 400G and 800G connectivity in a 1U fixed-configuration form factor, purpose-built for AI/ML spine-and-leaf fabric deployments. With 24x 400G QSFP112 front ports and 8x 800G OSFP uplink ports, this switch provides the port density and throughput required for high-performance compute clusters, hyperscale spine connectivity, and next-generation AI data centre fabrics. This variant ships with AC power and AFO (front-to-back) airflow for standard hot-aisle/cold-aisle deployments, and includes a 4-post tool-less rack mount kit for rapid installation.

Running Junos OS, the QFX5140 integrates seamlessly into Juniper's broader QFX switching portfolio and supports flexible QSFP112/QSFP56 channelisation for investment-protected migration paths.

FAQs

Q: What is the QFX5140-24CD8O-AO designed for?
A: It is designed for high-performance AI/ML data centre fabric deployments, specifically spine-and-leaf architectures requiring ultra-high-density 400G and 800G connectivity in a compact 1U form factor.

Q: What ports does the QFX5140-24CD8O-AO include?
A: The switch includes 24 x 400G QSFP112 front ports and 8 x 800G OSFP ports, providing extensive bandwidth for both leaf-level server connectivity and high-capacity spine uplinks.

Q: What does the AFO airflow designation mean?
A: AFO stands for Airflow Out, meaning air flows from the port side (front) to the power supply side (back). This is suited for standard hot-aisle/cold-aisle data centre deployments where cold air enters from the front.

Q: Does the QFX5140-24CD8O-AO include a rack mount kit?
A: Yes, this SKU ships with a 4-post tool-less rack mount kit, enabling quick and easy installation in standard 19-inch data centre racks without additional hardware or tools.

Q: What operating system does the QFX5140 run?
A: The QFX5140 runs Juniper's Junos OS, providing a consistent, feature-rich networking platform with support for automation, telemetry, and integration with Juniper Apstra for intent-based networking.

Q: Can I purchase the Juniper QFX5140-24CD8O-AO in Australia from IP Trading?
