Expansion module Sophos FleXi Port for XGS 5500/6500 — 40 Gigabit QSFP+ x2

The Sophos FleXi Port expansion module for XGS 5500/6500 adds two QSFP+ slots that support 40 Gigabit connectivity for uplink or aggregation purposes. Designed to integrate with compatible Sophos XGS chassis, the module provides a compact way to increase available bandwidth and consolidate high-speed links without replacing the core switch. The module is intended for use in data center edge, aggregation and campus switch deployments where high-throughput interconnects are required.

Advantages

The module delivers two 40 Gigabit QSFP+ ports that enable higher throughput and simplified link consolidation compared with multiple lower-speed ports. Its form factor is compatible with XGS 5500 and XGS 6500 platforms, allowing straightforward installation into existing chassis. By providing native 40 Gb interfaces, the module supports common QSFP+ transceivers and breakout cable options for flexible connectivity. The design reduces the number of physical uplink ports needed while maintaining predictable performance and reducing cabling complexity.

Suitable for

• High-throughput uplinks between access and aggregation switches
• Data center top-of-rack or spine connectivity requiring 40 Gb links
• Network consolidation where multiple 10 Gb links are aggregated to 40 Gb
• Environments that use QSFP+ transceivers or QSFP+ to multiple SFP+ breakout cables

Key specifications

• Interface: 2 × QSFP+ ports
• Port speed: 40 Gigabit per port
• Supported form factor: module compatible with specified XGS chassis
• Use case: uplink and aggregation for high-bandwidth networks
• Physical connection types: QSFP+ transceivers and breakout cable support

How to use

Install the expansion module into an available module slot on a compatible XGS 5500 or XGS 6500 chassis following the switch vendor's hardware installation procedures. After physical installation, power on the chassis and verify that the switch recognizes the new module using the management interface or console. Populate the QSFP+ ports with appropriate transceivers or breakout cables and configure link aggregation, VLANs, or routing as required by the network design. Monitor link status and throughput through the switch management tools to confirm proper operation.

Usage recommendations

Use certified QSFP+ transceivers and quality breakout cables that match the required reach and media (copper or fiber). When consolidating multiple 10 Gb links into a 40 Gb interface, verify switch firmware supports the intended breakout configurations and configure LACP or equivalent link aggregation to maintain redundancy and balanced traffic distribution.
