Some Extreme Networks switches support the use of 100 Gb QSFP28 pluggable optical modules. These modules provide four 25-gigabit transmit and receive channels in a single module, for an aggregate bandwidth of 100 Gbps.
You can insert or remove QSFP28 modules without powering down the system.
The information in this guide about hardware platform support for QSFP28 modules is current as of the date this guide was published. Support for QSFP28 modules 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 QSFP28 modules, refer to the most recent version of the Extreme Optics website.
