HPE QSFP28 to SFP28 Adapter - 845970-B21

HPE 845970-B21 QSFP28 to SFP28 Adapter

Overview

The HPE 845970-B21 is a QSFP28 to SFP28 adapter designed to bridge the gap between 100 Gigabit Ethernet (100GbE) and 10 Gigabit Ethernet (10GbE) interfaces. This adapter allows you to connect an SFP28 transceiver into a QSFP28 port, effectively downspeeding a 100GbE interface to 10GbE. This is critical for network infrastructure where you need to connect lower-speed devices or segments to higher-speed backbone links without over-provisioning or requiring entirely new hardware. It's a cost-effective solution for phased network upgrades or integrating legacy equipment into modern high-bandwidth environments.

Compatibility

This adapter is compatible with HPE ProLiant DL380 Gen10 Plus servers and other HPE networking equipment that utilize QSFP28 ports and require support for SFP28 transceivers. It is specifically designed to work within the HPE ecosystem, ensuring reliable interoperability with HPE switches and network interface cards (NICs) that feature QSFP28 ports. Always verify your specific HPE server or switch model's documentation for QSFP28 port compatibility with SFP28 adapters.

Installation Notes

Install the SFP28 transceiver into the adapter first, then insert the combined unit into the QSFP28 port on your HPE equipment. Ensure the port is clean and free of debris. The adapter itself does not require configuration; it is a passive device that relies on the host port and the installed transceiver for functionality. No specific torque values are required beyond ensuring a secure seated connection.
