Optional Modules
S3100 series supports an optional small form-factor pluggable plus (SFP+) or 10GBase-T module.
In S3100 series, the hot swap of optional modules is supported with the following behavior:
• If you change the same type of optional module, then the old configuration is retained.
• If you change a different type of optional module, then the optional module is moved into error state.
• You can modify the configuration of optional module interfaces, only if the optional module is present.
• After removing the optional module, you need to wait for the syslogs to be removed before inserting the optional module again. You
cannot insert the module immediately.
