3. Front Panel Port Layout & Copper Interface Specifications

Port Numbering & FTW Bypass Pair Configuration

1. Bypass Pair 1: Port 1 & Port 2 (controlled by B1 bypass LED)
2. Bypass Pair 2: Port 3 & Port 4 (controlled by B2 bypass LED)
3. Bypass Pair 3: Port 5 & Port 6 (controlled by B3 bypass LED)
4. Bypass Pair 4: Port 7 & Port 8 (controlled by B4 bypass LED)
   When triggered by a system failure, each pair forwards traffic at Layer 1 without firewall processing to avoid network outagesCisco.

• Maximum Transmission Distance: Up to 100 meters over standard Cat5e UTP cable
• Auto-Negotiation & Auto-MDI/MDIX: Enabled by default on all ports, automatically matches link speed, duplex mode, and resolves crossover cable connections
• Layer 1 Digital Status Monitoring: Real-time port link status, traffic activity, and bypass mode indication via front-panel bi-color LEDs

Front Panel LED Indicator Definition

1. Port Ethernet LEDs
   • Off: No physical link detected
   • Solid Green: Valid stable link established
   • Flashing Green: Active bidirectional data traffic transmission
   • Solid Amber: Link fault, cable disconnection, or port administrative shutdown
2. Four Independent Bypass Status LEDs (B1/B2/B3/B4 for each port pair)
   • Solid Green: Standby normal operation, bypass disabled, traffic processed by firewall
   • Flashing Amber: Hardware bypass mode activated (power loss, FTD crash, critical system fault)Cisco

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

• Automatic Layer 1 cut-through traffic forwarding between paired ports upon chassis power loss, critical FTD system crash, or security software failure
• Bypass operation runs purely at electrical physical layer without CPU, firmware, or chassis power intervention, eliminating full network outage risks for inline security deployments
• Only fully matched bypass port pairs can be configured as inline security sets; mixed bypass/non-bypass port inline sets are unsupported by FTD softwareCisco

5. Performance & Electrical Environmental Specifications

Bandwidth & Throughput Metrics

• Non-blocking full-duplex total module aggregate bandwidth: 8 Gbps bidirectional (1 Gbps per copper port)
• Hardware-accelerated NGFW/IPS threat inspection throughput: Up to 6.4 Gbps with full Snort 3 IPS, AVC application visibility, AMP malware protection, and URL filtering enabled
• TLS/SSL decryption capacity: Dedicated cryptographic engine offloads SSL/TLS processing, reducing host chassis CPU utilization
• NetFlow v9 traffic sampling fully offloaded to module ASIC to reduce overall chassis CPU load

Latency & Packet Buffer

• Port-to-port forwarding latency under hardware bypass cut-through mode: <2.5 μs
• Full threat inspection store-and-forward latency (IPS + AES-256 IPsec encryption active): <30 μs
• Shared dynamic allocation deep packet buffer to eliminate packet drops during bursty enterprise branch, IoT, and industrial control network traffic
