Juniper QFX5200-32C-AFO — 32-Port 100GbE QSFP28 Spine/Aggregation Switch
Technical Identity
The Juniper Networks QFX5200-32C-AFO is a 1U data center access and aggregation switch with 32x QSFP28/QSFP+ ports operating at 100GbE or 40GbE, delivering 6.4 Tbps aggregate throughput and 3.2 Bpps per the Juniper QFX5200 datasheet. Each QSFP28 port supports 1x100GbE, 2x50GbE, or 4x25GbE breakout, and each QSFP+ mode supports 1x40GbE or 4x10GbE. Note: the label on this unit reads QFX5200-32C-AF0 (zero) — a label rendering of the official AFO airflow-out suffix. Condition: Refurbished.

Engineering Context
The QFX5200-32C is built around a 6.4 Tbps Packet Forwarding Engine and was positioned by Juniper for high-density 100GbE fabric deployments. With flexible per-port breakout, one chassis can serve as a 100GbE spine, a 40GbE aggregation layer, or a dense 25GbE/10GbE fan-out stage, all managed under Junos OS. The AFO airflow model matches hot-aisle / cold-aisle rows with ports facing the cold aisle.
Use Cases
100GbE spine or aggregation in leaf-spine fabrics
40GbE aggregation with a migration path to 100GbE optics
Dense 25GbE/10GbE server fan-out via QSFP28/QSFP+ breakout cables
IP fabric and EVPN-VXLAN designs on the QFX5200 platform (verify features and licensing per Juniper documentation)
What This Is NOT
NOT a 400GbE / QSFP-DD platform. Ports are QSFP28 100GbE (or QSFP+ 40GbE).
NOT the AFI (back-to-front) variant. AFO means front-to-back airflow; match your rack design.
NOT the QFX5200-48Y (SFP28-based model); this is the 32x QSFP28 configuration.
NOT an InfiniBand switch. The QFX5200 is Ethernet only.
NOT supplied with transceivers, breakout cables, or rack accessories unless explicitly stated in the listing.
NO Juniper software licenses or support contracts are included or transferred.
Compatibility & Hard Constraints
Optics and cables: Juniper-qualified QSFP28/QSFP+ optics, DACs, and breakout assemblies; verify against the QFX5200 hardware compatibility list.
Breakout configuration: port profiles for 4x25G / 2x50G / 4x10G operation must be configured and verified for your Junos release.
Airflow and power: AFO airflow with 850 W redundant PSUs; confirm AC or DC PSU fitment against the unit label.
Label note: the unit label reads QFX5200-32C-AF0; buyers should treat this as the AFO airflow variant and verify against the physical unit.
Pre-deployment verification: confirm Junos release, port profiles, PSU type, and airflow before deployment.
Frequently Asked Questions (FAQ)
Q. What is the Juniper QFX5200-32C-AFO?
The QFX5200-32C-AFO is a 1U Juniper QFX5200 data center switch with 32x QSFP28/QSFP+ ports at 100GbE or 40GbE, 6.4 Tbps aggregate throughput, redundant 850 W power supplies, and front-to-back (AFO) airflow, running Junos OS.
Q. What breakout modes does the QFX5200-32C support?
Per the Juniper datasheet, each QSFP28 port supports 1x100GbE, 2x50GbE, or 4x25GbE, and each QSFP+ mode supports 1x40GbE or 4x10GbE using breakout cables. Port profiles must be configured in Junos.
Q. Why does the label read QFX5200-32C-AF0 instead of AFO?
The official Juniper ordering suffix is AFO (airflow out). The unit label renders the suffix as AF0 with a zero; the product sold is the AFO airflow-out variant and should be verified against the physical unit.
Q. Is the QFX5200-32C an InfiniBand switch?
No. The QFX5200-32C is an Ethernet switch only. It does not run InfiniBand protocols.
Q. Are Juniper licenses included with this QFX5200-32C-AFO?
No license or support entitlement is included or claimed. Advanced Junos features may require Juniper feature licenses purchased separately per Juniper policy.
Q. What condition is the QFX5200-32C-AFO supplied in by T.E.S IT-SOLUTIONS?
