Cisco FPR2140-ASA-K9 Firepower 2140 1U ASA Image Modular Firewall

Modular connections for an ASA deployment

FPR2140-ASA-K9 identifies the ASA order of the Cisco Firepower 2140, a 1 RU firewall with one network-module bay. Twelve copper Ethernet connections run at up to 1 Gbps; four fixed SFP+ connections support 1 or 10 Gbps. The optional module bay is the important distinction from a fixed-interface Firepower 2110 or 2120. It does not establish that an expansion module or optical transceivers are included in the offered unit.

Plan maintenance around removable components

Cisco describes two power-supply slots and a removable fan tray for the 2140. The network module is not hot-swappable, so an interface expansion needs an outage plan even though supported power and fan components can be replaced while operating. Record the installed module, supply type and airflow path before selecting a replacement chassis.

Separate appliance identity from support eligibility

The amended Cisco notice lists this exact ASA PID: manufacturer sales ended on May 27, 2025, and new service attachment ended on May 27, 2026. The last support date is May 31, 2030, subject to the applicable entitlement. An ASA-labelled appliance or a quoted hardware price does not by itself confirm active support, software rights or an FTD subscription.

Check the serial number for the memory notice

Cisco FN74199 includes the Firepower 2140 ASA order among products that can contain affected DIMMs. Applicability is determined by the chassis serial number, not by assuming every 2140 is defective. Obtain that identifier and any completed remediation record before accepting a replacement.
