Are the 2 x 10 gigabit Ethernet ports backward compatible to 1 gigabit Ethernet for the interim until we can replace our 6509e with a 9407R?

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."
