Cisco FPR2120-NGFW-K9 Firepower 2120 1U FTD Image Firewall Appliance

A fixed-interface Threat Defense appliance

FPR2120-NGFW-K9 is the Cisco Firepower 2120 NGFW appliance order. Its 1 RU chassis provides twelve RJ-45 data interfaces up to 1 Gbps and four 1-Gbps SFP interfaces. These four fiber connections are not the 10-Gbps SFP+ ports used on the larger 2130 and 2140. A separate copper management connection supports administration.

Expansion and power are physical limits

The 2120 has no network-module slot and uses one fixed AC power supply. Adding a second hot-swappable supply or an eight-port network module is therefore not a chassis upgrade path. Its fixed fans are not field-replaceable components. Check whether the existing network can fit within those limits before selecting this unit for replacement work.

An NGFW order is not a subscription inventory

The exact ordering row establishes the appliance identity. It does not prove which optional security subscriptions are active on a particular unit or which software release is installed. Record the intended Threat Defense management method and validate the required software and entitlements separately from the hardware quotation.

Lifecycle and unit-level checks

This PID appears in Cisco EOL15548: end of sale was May 27, 2025; the general software-maintenance and new service-attachment milestones were May 27, 2026. Applicable support ends May 31, 2030. Cisco also lists this order in FN74199, where serial-number validation determines whether the memory issue applies. Ask for the chassis serial number and remediation history rather than treating the model name as a health certificate.
