Not able to detect the 1G SFP

Solution

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, install an SFP module in port 1 and the reboot the system.

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 has to be 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.

Note for 1 G SFP to be detected make sure it is MSA compliant.
