Core Positioning

2. Chassis & Hardware Compatibility

Supported Hardware Platforms

• Cisco Secure Firewall 4200 Series all chassis models (4210, 4215, 4225, 4245)
• Installable into front-panel NM-2 and NM-3 module slots of 4200 chassis
• Single-wide form factor, supports hot-swap replacement with same-type module (ports must be administratively disabled first)Cisco

Required Software Versions

• Firepower Threat Defense (FTD): Minimum version 6.4
• ASA Firewall OS: Minimum version 9.14
• FXOS Chassis Manager firmware must be upgraded to matched compatible release to recognize the moduleCisco

3. Port & Interface Specifications

Front Panel Port Layout

• Pair 1: Port 1 (top) & Port 2 (bottom), controlled by B1 bypass LED
• Pair 2: Port 3 (top) & Port 4 (bottom), controlled by B2 bypass LED
• Pair 3: Port 5 (top) & Port 6 (bottom), controlled by B3 bypass LED
• Pair 4: Port 7 (top) & Port 8 (bottom), controlled by B4 bypass LED
  Port numbering rule: Top ports odd-numbered, bottom ports even-numbered, left to right sequenceCisco.

Optical Transceiver Compatibility

1. 10-Gigabit Ethernet: SFP+ SR, LR, ER, ZR transceivers
2. 1-Gigabit Ethernet: Standard SFP SX, LX, LH transceivers
   Restriction: Copper SFP transceivers can only be populated on either the entire top row or entire bottom row; mixed-row copper SFPs are physically incompatible due to internal spacing limits.

Hardware Fail-to-Wire (FTW) Bypass Feature

• Each paired port set automatically forwards traffic between the two ports if the firewall chassis loses power, crashes, or the security software fails
• Bypass mode operates entirely at physical layer without CPU/software intervention, preventing total network outage during appliance faults
• Dedicated bypass status LEDs (B1–B4) show bypass operational state for each port pairCisco.

4. Performance & Electrical Specifications

Throughput Capacity

• Non-blocking full-duplex total module bandwidth: 80 Gbps bidirectional
• Practical threat inspection throughput (full IPS, AMP, URL filtering enabled): Up to 20 Gbps per module

Latency Metrics

• Port-to-port forwarding latency (bypass mode): < 2 μs
• Latency with full AVC, IPS deep packet inspection enabled: < 120 μs (IPsec AES-256 encryption active)

Power Consumption

Environmental Compliance

• Operating temperature range: 0°C to 40°C (32°F – 104°F); performance derates 1% per °C above 35°C
• Operating relative humidity: 10% – 85% non-condensing
• Storage & transit temperature: -40°C to 70°C (-40°F – 158°F)
• NEBS Level 3 certified for telecom carrier-grade deployments.

5. Key Functional Features

1. Hardware Bypass Resilience: 4 independent fail-open port pairs to maintain network connectivity during appliance failure or power loss
2. Dual-Rate SFP+ Support: Flexible mixing of 1G and 10G optical links for mixed-speed campus and data center connections
3. Hot-Swap Support: Same-module replacement without full chassis power cycle (administrative port shutdown required before swap)
4. Comprehensive Security Feature Offload: Works with Firepower appliance ASICs to accelerate IPS inspection, AVC application identification, IPsec VPN encryption, NetFlow v9 traffic sampling
5. Status LED Indicators: Per-port link/activity LEDs + dedicated bypass pair status LEDs for rapid fault troubleshooting
6. Multi-Context Virtual Firewall Compatible: Supports independent security context traffic segmentation for multi-tenant network environments

6. Typical Deployment Use Cases

1. Data Center Inline Security: Deploy as inline inspection links between server farm aggregation switches and core routers, with hardware bypass to avoid data center outages
2. Campus Network Segmentation: Inspect inter-VLAN user, IoT and server traffic, enable automatic bypass for campus core connectivity resilience
3. Branch Office Aggregation Edge: Consolidate multiple remote branch VPN links on high-density 10G ports
4. Hybrid Cloud Gateway: Aggregate SaaS and cloud provider interconnect traffic with encrypted traffic analytics (ETA) threat inspection
5. OT/IoT Industrial Network Protection: Inline filtering of industrial protocols with fail-open bypass to preserve critical industrial control network connectivity
