SFP+ Module Lenovo 10/25GbE 4M17A13529 — compatible small form-factor pluggable transceiver

The Lenovo SFP+ Module 10/25GbE is a removable small form-factor pluggable transceiver designed for use in compatible switches, routers and network adapters. It supports both 10 Gigabit and 25 Gigabit Ethernet speeds to provide high-throughput uplinks and interconnects in data center and enterprise environments. The transceiver is hot-swappable and intended to deliver low-latency, reliable links for server-to-switch and switch-to-switch connections, enabling flexible network scaling and straightforward maintenance.

Advantages

This SFP+ module offers dual-rate support for 10GbE and 25GbE to accommodate mixed equipment and phased upgrades. Compact SFP+ form factor reduces port density constraints while maintaining high performance. Hot-pluggable design allows replacement or upgrades without powering down connected equipment, minimizing service interruptions. The module is engineered for low latency and reliable signal integrity over appropriate cabling, supporting stable operation in standard enterprise networking scenarios.

Suitable for

• High-speed uplinks between servers and top-of-rack or spine switches
• Inter-switch connections in data center aggregation and spine-leaf architectures
• Network adapter ports in servers and storage appliances requiring 10GbE or 25GbE
• Environments needing hot-swappable transceivers for maintenance and upgrades

Key specifications

• Form factor: small form-factor pluggable (SFP+)
• Supported link speeds: 10 Gigabit Ethernet and 25 Gigabit Ethernet
• Interface: electrical/optical pluggable transceiver compatible with standard SFP+ ports
• Latency: designed for low-latency operation suitable for server and switch interconnects
• Hot-swappable: supports insertion and removal without system downtime
• Typical operating environment: data center and enterprise network equipment

How to use

Insert the module into a compatible SFP+ slot on a switch, router or network adapter until it seats firmly and the retention latch engages. The module is hot-pluggable, so it can be installed or removed while the host device is powered, but follow your equipment vendor's hot-swap procedures to avoid transient link effects. Connect the appropriate cable type for the selected speed and distance—ensure cable and connector types meet the performance requirements for 10GbE or 25GbE links. Verify link status and speed through the host device management interface and monitor for expected link indicators.

Recommendations

Use vendor-compatible hardware and certified cables to ensure optimal performance and compatibility. Confirm that firmware and driver versions on switches, adapters and host systems support dual-rate 10/25GbE operation. For critical links, test link stability and throughput after installation and keep spare modules available for rapid replacement during maintenance windows.
