FPR4145-ASA-K9 Description
FPR4145-ASA-K9 is a Cisco Firepower 4145 ASA firewall appliance in the Firepower 4100 Series, built as a 1RU security platform for data center and enterprise edge ASA deployments. Cisco identifies this exact PID as the Firepower 4145 ASA appliance with two network module bays; the 4145 ASA profile provides 80 Gbps stateful inspection firewall throughput, 50 Gbps multiprotocol firewall throughput, 40 million concurrent firewall connections, and 23 Gbps IPsec VPN throughput, with 384 GB memory and dual 1100W AC power in the current hardware profile.

Product Performance
Key Features
Cisco lists FPR4145-ASA-K9 as the 4145 ASA appliance PID, so the quote should preserve the ASA role when the design is not moving to Threat Defense or NGIPS.
The 4145 hardware row carries 384 GB memory, which is double the 4115 and 4125 memory entries in Cisco’s Firepower 4100 hardware table.
The 4145 ASA table raises multiprotocol firewall throughput to 50 Gbps while keeping the 80 Gbps stateful inspection entry shared by the 4115 and 4125 ASA rows.
The appliance includes eight on-chassis SFP+ data ports that can be planned for 1G or 10G optics according to Cisco-supported transceiver lists.
Two network module bays allow Cisco-listed 1G, 10G, 40G, 100G, and hardware-bypass module choices, subject to the selected software release and optics plan.
Cisco requires Firepower 4100 deployments to keep FXOS compatible with the ASA logical-device version, making the software target part of the technical order check.
Application Scenarios
Choose FPR4145-ASA-K9 when the approved firewall design stays on Cisco Secure Firewall ASA and the sizing worksheet requires the 4145 connection and multiprotocol throughput profile.
Use this SKU when the rack plan needs a 1RU Firepower 4100 appliance with eight fixed SFP+ data ports plus two bays for Cisco-confirmed network modules.
Select this appliance when procurement must keep the Firepower 4145 hardware tier but the software role must remain ASA rather than the FPR4145-NGFW-K9 orderable identity.

- In a FPR4145-ASA-K9 vs FPR4125-ASA-K9 comparison, both are 1RU ASA appliances with 800 GB storage and dual 1100W AC power, while FPR4145-ASA-K9 adds 384 GB memory, 50 Gbps multiprotocol throughput, 40 million concurrent connections, and 1.5 million new connections per second.
- The FPR4145-ASA-K9 difference from FPR4145-NGFW-K9 is the orderable software role: Cisco lists the same 4145 hardware tier, but the current SKU is the ASA appliance and the comparison SKU is the NGFW appliance.
- For buyers comparing FPR4145-ASA-K9 vs FPR4125-ASA-K9, the 4145 should be ordered only when the approved design needs the larger memory and ASA scale entries shown in the Cisco table.
- In a FPR4145-ASA-K9 vs FPR4145-NGFW-K9 comparison, which model to choose depends on whether the deployment standard names ASA or NGFW as the Cisco orderable appliance role.
Selection Guide
1. Keep the software role explicit
Select FPR4145-ASA-K9 when the network security design names the Firepower 4145 ASA appliance and not a Threat Defense or NGIPS PID.
2. Use the 4145 row for upper-tier ASA sizing
Match this SKU to projects that require 50 Gbps ASA multiprotocol throughput, 40 million concurrent connections, 1.5 million new connections per second, or 23 Gbps IPsec VPN throughput.
3. Downshift only when the 4125 row is sufficient
Choose FPR4125-ASA-K9 instead only if 192 GB memory, 45 Gbps multiprotocol throughput, and 25 million connections satisfy the approved sizing file.
4. Treat modules and software as one order check
Confirm the ASA and FXOS release target before adding fixed-port optics or expansion modules, especially if the design includes 100G network-module support.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact appliance PID |
FPR4145-ASA-K9 rather than FPR4145-NGFW-K9 or FPR4145-NGIPS-K9 |
Cisco separates ASA, NGFW, and NGIPS appliance orderable identities for the 4145 platform |
|
ASA and FXOS release path |
Target ASA version and compatible FXOS version for Firepower 4145 |
Firepower 4100 logical devices require supported software combinations |
|
Fixed-port optics |
Supported SFP or SFP+ transceivers for the eight on-chassis data ports |
The appliance ports depend on matched optics before cabling and support validation |
|
Network module selection |
Required 1G, 10G, 40G, 100G, or hardware-bypass network module |
The two module bays determine expansion ports and can add software-release requirements |
|
Power and cords |
Dual 1100W AC power supplies and approved regional power cords |
Rack readiness depends on the installed power modules and site power standard |
|
SSD and service parts |
800 GB SSD profile, fan spares, rack kit, and cable-management accessories |
Serviceable components should match the installation and support plan |
|
ASA license and Smart Account |
ASA configuration license requirement and end-customer Smart Account association |
Cisco’s ordering flow includes licensing and Smart Account steps before the ASA appliance order is completed |
