FPR4115-ASA-K9 Description
FPR4115-ASA-K9 is the Cisco Firepower 4115 ASA appliance in the Cisco Secure Firewall 4100 Series, a 1RU firewall for ASA-based internet edge, data center edge, or VPN deployments that need the 4115 performance tier. Cisco identifies this PID as a Firepower 4115 ASA appliance with two network module bays, and the 4115 platform provides eight on-chassis 10G SFP+ data ports, 80 Gbps stateful inspection firewall throughput, 40 Gbps ASA multiprotocol firewall throughput, 15 million concurrent firewall connections, and 15 Gbps IPsec VPN throughput.

Product Performance
Key Features
FPR4115-ASA-K9 is the Cisco-listed ASA appliance PID for the Firepower 4115, which keeps the order aligned with ASA operation instead of the NGFW or NGIPS appliance PIDs.
The 4115 ASA tier raises the Cisco-listed firewall throughput and connection scale above the 4112 model while preserving the 1RU two-network-module appliance format.
Eight on-chassis 10G SFP+ ports provide the base data interface set, and the two network module bays support Cisco-listed Firepower 4100 expansion modules.
Cisco’s 4115 hardware table lists 192 GB memory and 400 GB storage, which helps differentiate this appliance from the lower 4112 tier and the 800-GB 4125/4145 storage profile.
Cisco documentation introduces ASA support for the Firepower 4115 at ASA 9.12(1) with the related FXOS requirement, so the selected software bundle must be checked against the current Cisco compatibility matrix.
The hardware guide lists field-replaceable fans, power supply modules, SSDs, rack-mount kit, network modules, and power-cord rules, making accessory verification part of the technical quote check.
Application Scenarios
Choose FPR4115-ASA-K9 for an ASA-based internet edge or data center firewall refresh when the approved sizing document calls for the 4115 performance tier instead of the lower 4112 model.
Select this SKU when procurement must keep the Firepower 4115 hardware but the security design names ASA as the appliance role, making FPR4115-NGFW-K9 the wrong orderable PID.
Use this appliance when the rack plan requires a 1RU Firepower 4100 chassis and the interface plan depends on fixed 10G SFP+ ports plus Cisco-confirmed network module expansion.

- In a FPR4115-ASA-K9 vs FPR4115-NGFW-K9 comparison, Cisco lists the same FPR-4115 hardware model, memory, storage, ports, and performance summary, while the PID description separates the ASA appliance from the NGFW appliance.
- The FPR4115-ASA-K9 difference from FPR4112-ASA-K9 is the model tier: the 4115 has 192 GB memory, 80G firewall summary performance, 40 Gbps ASA multiprotocol throughput, and 15 million concurrent firewall connections, while the 4112 has lower listed values.
- For FPR4115-ASA-K9 vs FPR4125-ASA-K9, both are 80G firewall summary ASA appliances, but the 4125 moves to 800 GB storage, 45 Gbps ASA multiprotocol throughput, 25 million concurrent connections, and a dual 1100W AC power configuration.
- Buyers deciding which model to choose should order FPR4115-ASA-K9 only when the BOM needs the Firepower 4115 ASA PID and the 4115 performance and storage profile match the approved design.
Selection Guide
1. Anchor the order on ASA identity
Select FPR4115-ASA-K9 when the firewall design explicitly requires a Firepower 4115 ASA appliance PID and not the 4115 NGFW or NGIPS orderable identity.
2. Use the 4115 tier for the documented sizing target
Choose the 4115 ASA model when 80 Gbps stateful inspection throughput, 40 Gbps multiprotocol firewall throughput, and 15 million concurrent connections fit the project sizing file.
3. Move to another 4100 model only for a confirmed gap
Compare FPR4112-ASA-K9 for a lower 4112 ASA tier or FPR4125-ASA-K9 for the 4125 storage, connection, and power profile; do not substitute either model without changing the approved bill of materials.
4. Close the appliance and accessory plan together
Verify software release, network modules, optics, SSD, fan spares, rack kit, AC or DC power supplies, and regional power cords before price and availability are finalized.
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact PID |
FPR4115-ASA-K9 rather than FPR4115-NGFW-K9 or FPR4115-NGIPS-K9 |
Cisco lists separate Firepower 4115 PIDs for ASA, NGFW, and NGIPS appliance roles |
|
Software plan |
ASA appliance requirement and the Cisco-supported ASA and FXOS release for the target deployment |
The 4115 ASA order should match the software image and compatibility plan |
|
Fixed-port optics |
Supported SFP/SFP+ transceivers for the eight on-chassis data ports |
Incorrect optics can delay cabling or support validation |
|
Network modules |
Required 1G, 10G, 40G, 100G, or hardware-bypass network module type |
The two module bays determine the firewall’s additional interface set |
|
Power design |
1100W AC, dual AC option, or 950W DC option plus regional power cords |
Power supply choice affects redundancy, rack power, and site installation |
|
Serviceable parts |
400-GB SSD, six fan modules, rack kit, cable management, and spare accessory needs |
The appliance should arrive with the parts needed for installation and support |
|
Commercial review |
Price, stock status, warranty support, and shipping destination after the technical BOM is locked |
Commercial checks should follow confirmed PID, power, module, and optics choices |
