Expansion Module Sophos XSBZTCHF6 — 2× Gigabit Ethernet, 4× Gigabit SFP

The Sophos XSBZTCHF6 expansion module adds physical network interfaces to compatible Sophos appliances, providing two Gigabit Ethernet copper ports and four Gigabit SFP slots for fiber or SFP-based copper transceivers. It is intended to increase interface capacity for routing, firewalling and uplink connections in environments that require a mix of copper and fiber connectivity. The module is suitable for branch offices, data centre edges and network refresh projects where additional ports are needed without replacing the base appliance.

Advantages

This expansion module supports both copper and fiber connectivity through two RJ45 Gigabit ports and four SFP slots, enabling flexible interface configuration. It simplifies upgrades by allowing extra ports to be added to compatible Sophos appliances without replacing the main unit. The compact, appliance-specific design maintains a consistent management and security feature set when integrated with the host device. Use of SFP slots allows selection of single-mode or multi-mode fiber transceivers or SFP copper modules to match existing network infrastructure.

Suitable for

• Expanding WAN or LAN interfaces on a compatible Sophos appliance
• Adding fiber uplinks at branch offices or data centre edges
• Network upgrades that require additional physical ports without replacing the firewall appliance
• Hybrid copper and fiber deployments that need SFP flexibility

Key specifications

• Ports: 2 × Gigabit Ethernet (RJ45), 4 × Gigabit SFP slots
• Speed: 1 Gbps per port (Gigabit)
• Form factor: module designed for compatible Sophos appliances
• Connectivity types supported: copper (RJ45) and fiber via SFP transceivers
• Use cases: routing, firewall uplinks, LAN segmentation, uplink aggregation

How to use

Install the expansion module into the dedicated expansion slot of a compatible Sophos appliance following the appliance manufacturer’s hardware installation instructions. After physical installation, power-cycle the appliance if required and verify the new interfaces appear in the appliance management console. Configure the new ports for the required roles (WAN, LAN, DMZ, trunk, or uplink) and apply appropriate network, security and routing settings through the appliance interface. Insert SFP transceivers matching desired fiber type or SFP copper modules into the SFP slots when fiber or alternative copper connections are needed.

Usage recommendations

Use SFP transceivers that are compatible with the installed fiber type and distance requirements; ensure link settings and duplex modes are consistent across connected devices. Confirm that the host appliance firmware supports the module and review resource and throughput capacity when adding multiple interfaces to avoid exceeding appliance limits.
