1. Short Official Part Number Label
FPR8120-K9: Cisco FirePOWER 8120 Modular NGIPS Security Chassis, 1U Rackmount, 3 Hot-Swap NetMod Slots, Dual Redundant Hot-Swappable AC Power Supplies, 24GB RAM, Solid-State Storage, Lights-Out Management, Max 4 Gbps Firewall Throughput / 2 Gbps Full IPS Inspection Throughput
2. Full Product Overview
The Cisco FirePOWER 8120 (FPR8120-K9) is a modular 1U rack-mount next-generation intrusion prevention chassis belonging to the legacy FirePOWER 8000 Series platform, designed for mid-sized enterprise internet perimeters, campus core segmentation, regional aggregation gateways and mid-tier MSSP multi-tenant inspection nodesCisco.
Built with purpose-built security acceleration hardware, this modular appliance delivers flexible port scalability via swappable network modules (NetMods) to mix 1G copper, 1G fiber and 10G SFP+ interfaces without chassis replacement. It balances moderate inspected throughput with resilient hardware redundancy, supporting inline fail-open bypass deployments for zero network downtime during power loss or hardware failure.
Powered by FXOS chassis management and Firepower Threat Defense (FTD), the FPR8120-K9 integrates Cisco Talos global threat intelligence to deliver end-to-end multi-vector protection against exploits, zero-day malware, encrypted threats and evasive attack techniques. Validated by independent NSS Labs testing, the FirePOWER inspection engine maintains low latency under full traffic loads while meeting strict compliance logging requirements for PCI DSS, HIPAA and GDPR.
This model reached End-of-Sale (EoS) December 15, 2017; available stock consists of surplus, tested refurbished units only, no new factory production. Stacking capability is not supported on the 8120 chassis.
