FAQs

Q: What does 'AFO' mean for the QFX5120-48Y-D-AFO2?
A: AFO stands for Airflow Out, also described as front-to-back airflow. This means cool air enters through the port side and exhausts out the rear of the chassis, which is the standard configuration for hot-aisle/cold-aisle data centre setups.

Q: Does this SKU include power supplies and fans?
A: Yes. The QFX5120-48Y-D-AFO2 ships with redundant DC power supplies and redundant fan modules included, making it ready for high-availability deployments out of the box.

Q: What software features are included with this switch?
A: This SKU ships with Juniper's base software features. Advanced features such as EVPN-VXLAN, advanced routing protocols, and analytics may require additional Junos licensing depending on your deployment requirements.

Q: Is the QFX5120 suitable for data centre spine or leaf roles?
A: Yes. The QFX5120 is purpose-built for data centre spine-and-leaf architectures, supporting EVPN-VXLAN overlay networking, BGP, and high-density 25G connectivity for modern cloud and enterprise data centre environments.

Q: Can I purchase the QFX5120-48Y-D-AFO2 in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is a specialist B2B IT hardware reseller delivering Juniper equipment across Australia. Contact us for pricing, availability, and lead times.

Q: What is the difference between DC and AC variants of the QFX5120?
A: The 'D' in this SKU denotes DC (direct current) power input, which is common in telco and data centre environments with centralised DC power plants. AC variants accept standard mains power and are used in typical enterprise data centre deployments.
