Juniper QFX5200-48Y Fan AFI | Switch Cooling, Hot-Swap, Enterprise

Protect switch availability with a fan module purpose-built for the Juniper QFX5200-48Y platform. In high-density network rows, thermal headroom is not optional; it is part of the uptime strategy. This replacement fan assembly supports the cooling profile required to keep the switch operating within its intended temperature envelope, helping reduce the risk of heat-related throttling or service interruption. For infrastructure teams, the value is in maintaining the original thermal design of the chassis rather than improvising with generic parts. That matters in production racks where airflow direction, fit, and service compatibility are tightly controlled. This module is intended for the QFX5200-48Y family, making it a practical choice for spares planning, field replacement, and lifecycle support. When a fan module fails, the cost is not the part itself — it is the exposure created while the chassis runs with reduced cooling capacity. Keeping the correct replacement on hand helps preserve operational continuity and avoids unnecessary risk during maintenance windows. For teams managing enterprise switching at scale, this is the kind of component that protects the rest of the investment.
