Frequently Asked Questions

What is the primary function of the HPE 845397-001 SFP28 module? +

The HPE 845397-001 is a high-performance SFP28 optical transceiver designed for 25GbE connectivity. It serves as a compact, hot-pluggable interface that allows your network switches or server adapters to transmit and receive high-speed data over fiber optic cabling, ensuring low-latency communication in demanding enterprise data center environments.

Which networking hardware is compatible with the HPE 845397-001? +

This module is engineered specifically for HPE networking platforms, including a wide array of HPE ProLiant servers, HPE FlexFabric switches, and other standard SFP28-compatible infrastructure. To ensure optimal performance and avoid link-down issues, we recommend verifying your switch firmware supports this specific transceiver before installation.

Can I use the HPE 845397-001 for 10GbE applications? +

While the 845397-001 is natively designed for 25GbE SFP28 throughput, backward compatibility depends entirely on the specific host switch or network interface card settings. Many HPE platforms allow for port speed configuration, but please consult your hardware’s documentation to confirm if the port supports down-clocking from 25G to 10G speeds.

What type of cabling is required for this SFP28 module? +

The HPE 845397-001 requires high-quality fiber optic cabling to maintain signal integrity at 25Gbps speeds. Ensure you are using the correct fiber type—typically OM3 or OM4 multimode fiber—that aligns with the transceiver's specifications for reach and bandwidth. Using lower-grade or damaged cabling can result in increased bit error rates or complete link failure.

Does the HPE 845397-001 require special software licensing? +

Typically, HPE SFP28 modules do not require individual software licenses to function once inserted into a compatible HPE port. The switch firmware automatically recognizes the transceiver during the power-on self-test. However, ensure your switch or server operating system is updated to the latest revision to maintain full compatibility and feature support.

How do I manage or monitor the HPE 845397-001 after deployment? +

You can monitor this transceiver through the host switch’s command-line interface or management software. Most HPE platforms provide Digital Optical Monitoring (DOM) data for this module, allowing you to track real-time optical power levels, transceiver temperature, and voltage, which is essential for proactive troubleshooting and maintaining network stability.

Is the HPE 845397-001 suitable for high-density rack deployments? +

Yes, the SFP28 form factor is specifically chosen for high-density environments. Its compact design allows for maximum port density on switch line cards, significantly increasing your bandwidth-per-rack-unit. The module is built for continuous operation and is designed to dissipate heat effectively within well-ventilated data center server racks.

What should I do if the HPE 845397-001 link status shows as down? +

First, verify that the module is fully seated in the port and the fiber cable is clean and securely connected. Check the switch port status via the CLI to see if the port is administratively 'up'. If issues persist, test the transceiver in a known-good port to rule out hardware failure or configuration mismatches.
