Core Positioning

2. Chassis & Software Compatibility

Supported Hardware Platforms

• All Cisco Secure Firewall 4200 series appliances (FPR4210, FPR4215, FPR4225, FPR4245)
• Installable into front-panel dedicated network module slots NM-2 and NM-3 of 4200 chassis
• Single-wide form factor; supports hot-swap replacement only with identical FPR4K-XNM-6X10SR-F module typeCisco

Mandatory Minimum Software Versions

• Firepower Threat Defense (FTD): Minimum release 7.2
• FXOS Chassis Manager firmware must be upgraded to matched compatible release to fully recognize and activate all module hardware bypass and inspection features

Critical Hardware Restrictions

• This module featuresfactory-built fixed SFP+ SR transceivers; individual transceivers cannot be removed, replaced, or swapped in the field. No separate SFP cages for user-installed opticsCisco
• Cross-model module replacement (installing different port/speed modules in its slot) requires full chassis reboot for hardware initialization
• Not compatible with legacy Firepower 4100 series appliances

3. Front Panel Port Layout & Optical Specifications

Port Numbering & Bypass Pair Configuration

1. Bypass Pair 1: Port 1 & Port 2
2. Bypass Pair 2: Port 3 & Port 4
3. Bypass Pair 3: Port 5 & Port 6
   Each pair operates with dedicated Layer 1 optical bypass switching components to forward traffic between paired ports when the firewall appliance fails or loses powerCisco

10GBase-SR Optical Transceiver Specs (Fixed Built-In)

• Interface Standard: 10GBase-SR 10 Gigabit Ethernet
• Fiber Type: OM2 / OM3 / OM4 multi-mode LC duplex fiber

4. Native Hardware Fail-to-Wire (FTW) Bypass Feature

• Automatic Layer 1 traffic forwarding between paired ports upon chassis power loss, critical FTD system crash, or security software failure
• Bypass operation runs purely at optical physical layer without CPU, firmware, or chassis power intervention, eliminating full network outage risks for inline security deployments
• Per-port bi-color LED indicators display real-time link status, traffic activity, and bypass activation state for rapid on-site fault diagnosis

5. Performance & Electrical Environmental Specifications

Bandwidth & Throughput Metrics

3. Line-Rate Encryption Offload: Hardware-accelerated AES-256-GCM IPsec VPN encryption/decryption running at full port line rate
4. Encrypted Traffic Analytics (ETA): Built-in acceleration for TLS 1.0/1.1/1.2/1.3 encrypted traffic inspection without full packet decryption, meeting HIPAA, PCI-DSS compliance requirements
5. Comprehensive Traffic Inspection Acceleration: ASIC offloading for Snort 3 IPS deep packet inspection, AVC full application identification, NetFlow v9 traffic sampling, and QoS traffic queuing
6. Multi-Context Virtual Firewall Support: Fully compatible with multi-context security virtualization to isolate independent tenant network traffic for managed security service providers
7. Real-Time Bi-Color Status LED Indicators: Per-port link/activity LED indicators for intuitive real-time hardware fault troubleshooting

7. Typical Enterprise & Industrial Deployment Use Cases

1. Data Center Inline Workload Segmentation: Deploy inline between leaf access switches and core aggregation switches to enforce granular security policies for virtual machine, Kubernetes cloud workloads, with hardware bypass to avoid critical data center connectivity outages
2. Enterprise Campus Core Security Inspection: Inspect aggregated inter-VLAN user, office IoT device and server traffic, leveraging three independent bypass pairs for segmented campus network resilience
3. OT/IoT Industrial Control Network Protection: Inline filtering of industrial Modbus, DNP3, IEC 60870 control protocols, fail-open bypass preserves critical production line connectivity during firewall maintenance or faults
