Condition: Refurbished

The FPR4K-FAN is a hot-swappable fan module used in the Cisco Firepower 4100/4000 Series security appliances. It is part of the system’s chassis cooling architecture and is required to maintain proper airflow and thermal stability for high-performance firewall operation. Each Firepower 4100 chassis uses six fan modules working together in an N+1 redundant cooling design, meaning the system can tolerate a single fan failure while continuing to operate, though all fans will run at higher speed and noise levels until replacement.

Features:

• Hot-swappable fan module (can be replaced without powering down the chassis) Used in Cisco Firepower 4100/4000 Series appliances as part of the cooling system Six-fan system design (N+1 redundancy) across the chassis for high availability Chassis-managed cooling – fan speed is automatically controlled by system temperature sensors
• Continuous operation monitoring with status reporting to the chassis management system LED status indicator (typically green = OK, amber = failure)
• Front-to-back system airflow support (aligned with data center hot-aisle/cold-aisle design) Redundant cooling support – system continues operating even if one fan fails (with higher fan speeds/noise)
• Field-replaceable unit (FRU) for quick maintenance in production environments Designed for enterprise-grade thermal reliability in high-density firewall workloads
