Frequently Asked Questions
What is the primary function of the HPE 1990-4725 SFP28 transceiver? +
The HPE 1990-4725 is a high-performance SFP28 module designed for high-speed data transmission across fiber optic networks. It is specifically engineered to provide 25GbE connectivity, making it an ideal solution for upgrading data center backbones, server-to-switch links, or enterprise campus distribution layers where low latency and high bandwidth throughput are critical requirements.
Which network equipment is compatible with the HPE 1990-4725 module? +
This SFP28 module is designed for seamless integration with a wide range of HPE networking hardware, including various HPE FlexFabric and Aruba switches. To ensure optimal performance and avoid link errors, always verify that the specific switch port supports SFP28 speeds and is compatible with the 1990-4725 standard before finalizing your deployment plan.
What is the maximum data rate supported by the HPE 1990-4725? +
The HPE 1990-4725 is optimized for 25 Gigabit Ethernet applications. By leveraging the SFP28 form factor, it provides a significantly higher bandwidth capacity compared to traditional SFP+ modules while maintaining a compact footprint. This makes it an efficient choice for organizations scaling their network infrastructure to meet the demands of modern cloud computing and storage workloads.
Does the HPE 1990-4725 support backward compatibility with SFP+ ports? +
While SFP28 and SFP+ ports share the same physical dimensions, compatibility depends on the specific hardware implementation of your host switch. Many modern HPE switches offer auto-negotiation, but you should consult your switch's datasheet to confirm if the 1990-4725 can operate at 10GbE rates, as this varies based on the transceiver's internal logic and the host platform's port capabilities.
What cabling infrastructure is required for this SFP28 transceiver? +
This module is designed for use with high-quality fiber optic cabling. Depending on your specific model requirements, you will typically use single-mode or multi-mode fiber with LC connectors to establish the link. Always ensure the fiber patch cables meet the required grade for 25G transmission to minimize signal loss and maintain the integrity of your high-speed data connections.
How do I manage and monitor the HPE 1990-4725 within my network? +
The module supports Digital Optical Monitoring (DOM), which allows administrators to access real-time diagnostic data. Through your HPE switch’s CLI or management interface, you can monitor parameters such as transmit and receive power, temperature, and voltage. This visibility is essential for proactive maintenance and identifying potential link stability issues before they impact overall network uptime.
What are the common deployment scenarios for the HPE 1990-4725? +
This transceiver is most frequently deployed in high-density data center environments, specifically for Top-of-Rack (ToR) switching, high-speed server interconnects, and inter-switch links (ISL). Its ability to handle 25Gbps throughput makes it perfect for alleviating bottlenecks in environments where virtualization, big data analytics, or high-performance computing clusters create heavy traffic loads across the network fabric.
Is the HPE 1990-4725 hot-swappable during operation? +
Yes, this SFP28 transceiver is hot-swappable, allowing you to install or replace the module in a powered-on HPE switch without interrupting the entire system. This feature is highly advantageous for enterprise environments, as it enables seamless hardware upgrades or rapid recovery from module failure without requiring scheduled downtime or impacting other active ports on the same chassis.
