Some Extreme Networks switches support the use of 25 Gb SFP28 pluggable optical modules. Each module provides one 25-gigabit transmit and receive channel.. Use of 25Gb SFP28 modules in QSFP28 ports requires the use of the QSFP28 to SFP28 adapter (part no. 10506).
Use only Extreme Networks-certified SFP, SFP+, and SFP28 modules in the SFP port on the hardware. These modules are available from Extreme Networks.
We recommend enabling Forward Error Correction (FEC) when you use 25 Gb SFP28 optical modules.
You can insert or remove SFP28 modules without powering down the system.
The information in this guide about hardware platform support is current as of the date this guide was published. Support for specific SFP28 types might have been added to other switches or I/O modules besides those listed in this guide.
For current information about hardware support and the minimum required software for SFP28 modules, refer to the most recent version of the Extreme Optics website.
