Discontinued legacy mid-sized enterprise & regional data center modular rack security hardware with limited remaining Cisco EOL support lifecycle, designed for medium enterprise headquarters, multi-region branch DMVPN aggregation hubs, multi-building small campus core edge and entry-level carrier MSP multi-tenant colocation segmentation requiring classic ASA feature set and flexible expandable fiber port density.

2. Complete Detailed Product Overview

Product Line Positioning

The Cisco FPR4110-ASA-K9 shares identical physical hardware chassis with FPR4110-NGFW-K9, but differs in factory logical device licensing: this PID is locked to run Cisco Secure Firewall ASA classic firewall software, while the NGFW variant runs Firepower Threat Defense unified NGFW OSCisco. It is the baseline dual-NetMod modular rack appliance in the Firepower 4100 generation, positioned below FPR4120-ASA-K9, FPR4140-ASA-K9 and FPR4150-ASA-K9 higher-performance ASA models.

Key hardware commonality with FPR4110-NGFW-K9: standard 19-inch 1RU rack form factor, dual independent NetMod expansion slots, native 8×10G SFP+ fixed fiber ports, split dual Intel/Cavium processor architecture, base 64GB DDR4 memory, single factory PSU with optional redundant secondary power supply. The split dual-chip design segregates basic ASA forwarding and heavy security offload (IPsec, TLS decryption, IPS) to avoid throughput degradation when multiple security services run simultaneously.

Critical software distinction: FPR4110-ASA-K9 operates classic ASA code with traditional firewall/VPN feature set, separate IPS image for threat inspection, no native AVC or SecureX integration without separate modules; FPR4110-NGFW-K9 runs integrated FTD unified threat software with built-in AVC, Talos IPS and cloud-native orchestration.

The K9 suffix delivers permanent Security Plus unrestricted licensing for ASA: removes DES encryption limits, enables full multi-context virtualization, unlimited TLS proxy, complete dual-mode HA and 1024 VLAN capacity, outperforming older fixed-port Firepower 2100 ASA appliances. Cisco fully ended production of the entire Firepower 4100 series in Feb 2024, replaced by Secure Firewall 4112/4115 modern refresh platforms.
