Hot Swapping SFP transceivers. Supported SFP transceivers that you can install in your Hewlett
Packard Enterprise OfficeConnect switch can be “hot swapped”. "Hot swapping" means supported
transceivers can be removed and installed while the switch is receiving power. Disconnect the network
cables from the SFP transceivers before hot-swapping them.
When you replace an SFP transceiver with another 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 Connections to Devices with Fixed Speed/Duplex Configurations. When connecting a device to
your switch port that contains an SFP transceiver, the speed and duplex settings of the switch port and
the connected device must match. If the settings do not match, the device may not link properly—you
may not get a link. For some older network devices, including some older Hewlett Packard Enterprise
devices, the default speed/duplex settings may be predefined. (For example, a setting might be 1000
Mbps/Full Duplex.) There may also be other settings that differ from the default configuration of your
switch port. Because of these default speed/duplex considerations, make sure that devices connected to
your SFP ports are properly configured. At a minimum, make sure the configurations match.
