Product Overview
The Juniper Networks QFX3500-MB-RJ45-AFO is a field-replaceable management board designed specifically for the QFX3500-48S4Q switch. It features a 1GbE RJ-45 interface along with 2x 1GE network ports, 1x USB port, and a dedicated console management port, providing comprehensive out-of-band management capabilities for data center switching environments. The module supports port-side-to-FRU-side (AFO) airflow, making it ideal for hot-aisle/cold-aisle data center deployments where front-to-back cooling is required. This is a genuine Juniper spare (FRU) intended to replace or supplement the management board in existing QFX3500-48S4Q deployments with minimal downtime.
