Frequently Asked Questions

What is the primary function of the HPE 1990-4721 SFP28 transceiver? +

The HPE 1990-4721 is a high-performance SFP28 transceiver designed to facilitate 25GbE connectivity across your enterprise network. It serves as a vital hardware component for linking switches, servers, and storage arrays, ensuring high-speed data transmission over compatible fiber optic cabling infrastructure in modern data center environments.

Which networking equipment is compatible with the HPE 1990-4721? +

This module is engineered for seamless integration with HPE networking hardware that supports the SFP28 form factor. It is specifically designed to meet the rigorous performance standards of HPE switches and interface cards, ensuring stable and reliable 25G performance without compatibility issues during high-bandwidth operations.

How does the SFP28 25GbE standard compare to traditional SFP+ modules? +

While SFP+ modules are limited to 10GbE speeds, the SFP28 standard utilized by the 1990-4721 provides a significant leap to 25GbE. This increased throughput allows for more efficient data handling and reduced latency, making it an ideal choice for upgrading server interconnects or backbone connections in environments where 10G is no longer sufficient.

What type of cabling infrastructure does the 1990-4721 require? +

This transceiver is designed to operate over high-quality fiber optic cabling. Depending on your specific network layout, it utilizes the appropriate optical standards to ensure maximum reach and signal integrity. It is best suited for environments currently utilizing LC-duplex fiber patches to connect high-speed server racks to top-of-rack switches.

Can the HPE 1990-4721 support lower speed connections? +

The 1990-4721 is optimized specifically for 25GbE operation. While some SFP28 ports may offer backward compatibility with 10G SFP+ modules, this specific transceiver is intended for high-speed 25G environments. Please verify your switch port configuration settings to ensure proper negotiation when deploying this unit in a high-density enterprise network architecture.

How do I ensure the 1990-4721 is properly seated in my switch port? +

Installation is straightforward; simply slide the module into an available SFP28 slot until you feel a secure click. It is recommended to perform this during a maintenance window to avoid any unintended disruption to your network traffic. Ensure the fiber cable is fully seated into the transceiver to maintain a low-loss, stable connection.

Does this transceiver require any specific software configuration? +

Generally, once physically installed into a recognized HPE switch, the 1990-4721 is auto-detected by the operating system. In some advanced enterprise scenarios, you may need to verify that the port is administratively enabled and configured for the correct speed via the switch command-line interface to ensure optimal link-up status.

What environmental conditions are ideal for the 1990-4721? +

This module is designed for standard data center environments that maintain controlled temperatures and humidity levels. Because it handles high-speed data transmission, it generates typical operating heat; therefore, ensuring proper airflow within your server rack or switch chassis is essential for maintaining the performance longevity and stability of the transceiver.
