Switching Between 10 G and 1 G
•
If there is nothing installed in port 1, the board will be configured for 10 G mode by default. Therefore, to switch to 1 G mode,
an SFP module must be installed in port 1 and the system needs to be rebooted.
•
Conversely, if an SFP module is installed and the user wants to switch to 4 x 10 G mode, then an SFP+ module must be installed
in port 1 and the WLC rebooted.
•
Thus, Online Insertion and Removal (OIR) of SFP and SFP+ between 10 G and 1 G is not possible.
•
OIR of 10 G to 10 G and 1 G and 1 G is possible.
It is recommended to have all ports as either 10 G or 1 G. In case they are different, port 1 SFP determines
the mode of operation and functionality on the other SFPs may not work.
