Cisco FPR2120-ASA-K9 Firepower 2120 1U ASA Image Firewall Appliance

ASA on a fixed-port Firepower platform

FPR2120-ASA-K9 denotes the ASA appliance order for the Cisco Firepower 2120. It occupies 1 RU and has sixteen fixed data interfaces: twelve RJ-45 Gigabit Ethernet ports plus four 1-Gbps SFP ports. The separate management interface and RS-232 console serve administration, and should not be counted as extra ordinary data connections.

When an existing ASA replacement fits

This chassis has no expansion-module bay. It uses one fixed AC supply and internal fans that are not field-replaceable. Before selecting it as a spare, map the installed data links and power design to those physical limits. Projects needing modular ten-gigabit expansion or redundant chassis power require a different hardware design.

Keep software rights separate from the chassis

The ASA ordering identity is different from an FPR2120-NGFW-K9 order. Confirm the deployed ASA release and applicable software rights for the actual equipment. A hardware quotation does not by itself establish Threat Defense subscriptions, active support coverage or a right to transfer existing licenses.

Review support eligibility before committing to a spare

Cisco lists the exact ASA PID in EOL15548. Manufacturer sales closed May 27, 2025, and the deadline for new service attachment was May 27, 2026. The published last support date is May 31, 2030, subject to entitlement. FN74199 also lists this order; use the chassis serial number to determine whether its memory components require the documented remediation instead of assuming that every unit is affected.
