FPR4112-ASA-K9 Description
FPR4112-ASA-K9 is a Cisco Firepower 4112 ASA firewall appliance in the Firepower 4100 Series for ASA-based edge, data center, or service-provider firewall deployments. Cisco identifies this exact PID as a 1RU Firepower 4112 ASA appliance with two network module bays, and Cisco Firepower 4100 documentation confirms eight fixed 1G/10G SFP+ ports, support for 1/10/40/100G network-module expansion, a single shipped 1100W AC power supply with optional redundant AC or 950W DC supplies, and Firepower 4112 performance figures including 40 Gbps firewall throughput, 10 million concurrent sessions, and 8.5 Gbps IPsec VPN throughput.

Key Features
FPR4112-ASA-K9 is the Cisco-listed ASA appliance PID for the Firepower 4112, so procurement should not substitute the NGFW or NGIPS PID unless the approved design changes.
The appliance uses a 1RU chassis with two network module bays, which helps projects keep the 4112 footprint while adding the approved I/O module set.
Cisco lists eight on-chassis SFP+ interfaces for the 4112 model, giving the firewall a fixed 10G base port set before optional network modules are added.
The ASA performance table confirms 40 Gbps stateful inspection throughput, 30 Gbps multiprotocol throughput, 9 Gbps IPsec VPN throughput, and 10000 maximum VPN peers for the 4112 model.
Cisco’s ASA capability table lists active/active or active/standby high availability and clustering up to 16 appliances, with final design limits tied to the current Cisco configuration guidance.
Power supplies, fans, SSD options, and rack accessories are listed as Firepower 4100 orderable components, so spares and regional power choices should be part of the firewall BOM.
Application Scenarios
Use FPR4112-ASA-K9 when the existing design standardizes on Cisco ASA operation and needs a Firepower 4112 appliance with fixed 10G SFP+ interfaces plus modular I/O expansion.
This SKU is appropriate when asset records, support contracts, or compliance approvals specify the FPR4112-ASA-K9 orderable PID and a different 4112 NGFW PID would change the requested software role.
Deploy the 4112 ASA appliance when the firewall design needs two network module bays for approved 1G, 10G, 40G, or 100G Firepower 4100 modules while keeping the 1RU chassis class.

- In a FPR4112-ASA-K9 vs FPR4112-NGFW-K9 comparison, the hardware model, 1RU form factor, two network module bays, and 4112 performance summary match, but Cisco’s PID description separates the ASA appliance from the NGFW appliance.
- The FPR4112-ASA-K9 difference from FPR4115-ASA-K9 is the model tier: the 4112 is listed with 40G firewall, 19G NGFW, and 19G IPS summary figures, while the 4115 is listed with 80G firewall, 33G NGFW, and 33G IPS summary figures.
- For buyers deciding which model to choose, order FPR4112-ASA-K9 when the BOM needs the 4112 ASA PID and move to FPR4115-ASA-K9 only when the approved firewall design calls for the higher 4115 ASA model.
Selection Guide
1. Match the exact ASA orderable PID
Select FPR4112-ASA-K9 when Cisco ASA operation is part of the approved firewall design and the requested PID is the Firepower 4112 ASA appliance.
2. Keep the 4112 tier when its ASA scale fits
Use the 4112 model when 40 Gbps stateful inspection throughput, 30 Gbps multiprotocol throughput, and 10 million concurrent firewall connections fit the sizing document.
3. Compare FPR4115-ASA-K9 for higher appliance scale
Move to FPR4115-ASA-K9 only if the design requires the 4115 model’s higher Cisco-listed performance summary while staying with an ASA appliance PID.
4. Finalize modules, optics, software, and power together
Confirm the two network module bays, supported transceivers, ASA software target, AC or DC power supply plan, rack accessories, and spare components before the quote is released.
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact PID |
FPR4112-ASA-K9 rather than FPR4112-NGFW-K9 or FPR4112-NGIPS-K9 |
Cisco lists separate 4112 orderable PIDs for ASA, NGFW, and NGIPS appliance roles |
|
Software role |
ASA appliance requirement and target release for the deployment |
Prevents ordering an appliance PID that does not match the firewall software plan |
|
Fixed ports |
Eight on-chassis 10G SFP+ interfaces and supported Cisco transceivers |
Ensures the base 4112 port set matches the edge or data center cabling plan |
|
Network modules |
Required Firepower 4100 network module type for the two module bays |
Determines whether extra 1G, 10G, 40G, 100G, or FTW connectivity must be ordered |
|
Power design |
1100W AC or 950W DC supply choice and redundancy requirement |
Site power and spare planning depend on the selected PSU type |
|
Serviceable parts |
400 GB SSD, six fans, rack kit, and approved power cords |
Helps procurement avoid installation delays after appliance delivery |
