Description
Sophos SG550 — Next-Generation Firewall
The Sophos SG 550 is a powerhouse 2U next-generation firewall engineered specifically for large-scale enterprise infrastructure, data centers, and demanding corporate networks. Utilizing advanced multi-core Intel processor architecture, it delivers the raw throughput needed to enforce comprehensive security policies across heavy traffic flows.
Hardware & Redundancy
Designed for zero-downtime environments, the SG 550 features a 2U rackmount chassis complete with sliding rack rails. It incorporates dual hot-swappable power supplies, dual hot-swappable RAID-1 SSDs, and front-accessible status indicators. This redundant design ensures continuous protection even in the event of a component failure.
Customization & Security
Through its FleXi Port expansion system, the SG 550 offers exceptional flexiblity. Administrators can outfit the device with various combinations of GbE copper, 1G/10G SFP/SFP+, or 40G QSFP+ modules. Powered by the Sophos UTM operating platform, it consolidates firewalling, intrusion prevention, web filtering, email security, and wireless management into a single manageable appliance.
Selection Guide
For Capacity & Throughput Planning
Evaluate your organization’s peak internet bandwidth, internal VLAN routing requirements, and concurrent user connection counts to ensure the SG 550’s 45 Gbps firewall throughput meets your needs.
For Interface Customization
Determine the required port types (1GbE RJ45, 1G Fiber SFP, 10G SFP+, or 40G QSFP+) and choose the appropriate 2U FleXi Port expansion modules prior to deployment.
For High Availability
Select two identical Sophos SG 550 units to establish an Active/Active or Active/Passive HA cluster using internal management ports.
Always Verify
Cross-reference your planned module selection with official Sophos FleXi Port hardware compatibility guides for 2U appliances.
Installation Notes
Mount the SG 550 into a standard 19-inch rack using the included 2U sliding rail kit. Connect both auto-ranging power cables to separate power sources (or UPS units) to leverage full power redundancy. FleXi Port modules should be securely installed into expansion slots before powering on the appliance. Initial setup can be completed via the front-panel LCD interface or by connecting directly to the dedicated management ports.
Best Practices
Always connect both power supplies to independent electrical circuits or dedicated UPS systems. Ensure adequate 2U rack spacing and ventilation for optimal airflow. Keep backup copies of appliance configuration files and firmware updates saved offsite. Monitor drive and system health via the local web console or Sophos UTM Manager (SUM).
