When you replace a SFP/SFP+/QSFP+ transceiver with another transceiver of a different type, the switch may
retain selected port-specific configuration settings that were configured for the replaced unit. Be sure to validate or
reconfigure port settings as required.
SFP/SFP+/QSFP+ connections to devices with fixed speed/duplex configurations
When connecting a device to your switch port that contains a SFP/SFP+/QSFP+ transceiver, the speed and
duplex settings of the switch port and the connected device must match. Otherwise, the device may not link
properly—you may not get a link. For some older network devices, the default speed/duplex settings may be
predefined (for example, to 1000 Mbps/Full Duplex), or otherwise set differently from the default configuration of
your switch. These setting differences may also apply to some older Hewlett Packard Enterprise devices.
Because of these default speed/duplex considerations, make sure that devices connected to your SFP/SFP+/
QSFP+ ports are properly configured. At a minimum, make sure the configurations match.
