Secondary NSA 3700 Firewall Unit for Active/Standby High Availability Failover with 24x GbE Ports, 10x SFP+ 10G Expansion, Dual Power Supplies, and Gen 7 SonicOS 7.0
The SonicWall NSA 3700 High Availability unit (02-SSC-7368) is a secondary firewall appliance that pairs with a primary NSA 3700 to create an active/standby failover configuration. When the primary firewall fails or loses connectivity, the HA unit automatically takes over all firewall, VPN, and security functions with no manual intervention, maintaining continuous protection for production network traffic. The HA unit is identical hardware to the standard NSA 3700: 24 GbE copper ports, 10 SFP+ 10G expansion slots, dual power supplies, and Gen 7 SonicOS 7.0 architecture in a 1U rack-mountable form factor.
The HA designation means this unit is licensed specifically as the standby partner in a high availability pair. It operates in passive mode during normal conditions, continuously synchronizing configuration, state, and session data from the primary unit, and activates only when the primary goes offline. This provides the same level of protection as running two fully licensed NSA 3700 firewalls at a significantly lower cost, making hardware redundancy accessible for large enterprises that require continuous firewall uptime across high-density network environments.
Where the NSA 3700 HA Fits
- Large enterprise networks with high port density and uptime requirements where the HA pair eliminates the firewall as a single point of failure, 24 GbE copper ports and 10 SFP+ 10G slots handle complex network segmentation and high-bandwidth 10G backbone connectivity, and automatic failover maintains VPN tunnels, security policies, and active sessions without manual intervention
- Data center edge and campus core deployments where the 1U rack-mountable form factor with dual power supplies provides hardware-level redundancy within the appliance itself, the NSA 3700 platform delivers multi-gigabit threat prevention throughput for encrypted and unencrypted traffic, and layer 4-7 clustering supports scalable high-availability architectures beyond simple active/standby pairs
- Regulated industries and compliance-driven environments where continuous network security coverage is required for audit and compliance purposes, the active/standby configuration provides sub-second failover for mission-critical transaction processing, and TAA compliance supports government procurement requirements for redundant network security infrastructure
What the NSA 3700 HA Delivers
- Active/Standby Failover: Continuously synchronizes configuration, state tables, and session data from the primary NSA 3700. Automatic takeover when the primary unit fails, maintaining VPN tunnels, security policies, and active sessions with minimal disruption to network traffic.
- Identical NSA 3700 Hardware: 24 GbE copper ports (10/100/1000Base-T), 10 SFP+ expansion slots for 10G fiber uplinks, USB port, and dual power supplies for hardware-level power redundancy. 1U rack-mountable form factor (16.9 x 12.8 x 1.8 inches, 10.14 lb).
- Gen 7 SonicOS 7.0 Platform: Full Gen 7 architecture with TLS 1.3 deep packet inspection, SD-WAN, Capture ATP support, RTDMI/RFDPI threat prevention, and layer 4-7 clustering. Single-pane-of-glass management for firewalls, switches, and access points.
- Cost-Effective Enterprise Redundancy: HA-licensed unit provides full hardware redundancy at a lower cost than deploying two independently licensed NSA 3700 firewalls. TAA compliant for government procurement. WEEE, RoHS, and REACH environmental compliance.
