You can insert or remove QSFP+ modules without powering down the system.
The information in this guide about hardware platform support for QSFP+ modules is current as of the
date this guide was published. Support for QSFP+ modules may 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 QSFP+ modules, refer to the most recent version of the ExtremeXOS
Hardware and Software Compatibility Matrix.

SR4 QSFP+ Module

The SR4 QSFP+ R4 module provides a 40-Gbps optical connection using MTP® (MPO) optical
connectors.
This optical module integrates four data lanes in each direction with 40 Gbps aggregatebandwidth.
Each lane can operate at 10.3125 Gbps up to 100 meters using OM3 fiber or upto150meters using OM4
fiber. The SR4 QSFP+ module conforms to the 802.3ba D3.2 (40GBASE-SR4)standard.
The SR4 QSFP+ module is supported in the following Extreme Networks switches and components:
