I have your SEE-G48-TG4 48ports switched, please confirm whether all 48ports in front support 10gbit speed without optional modules AOM-SEE-X2C or AOM-SEE-X2F switched?
Negative, all 48ports running at 1gbits without AOM-SEE-XC2 or AOM-SEE-X2F switched. In order to have 10gbits bandwidth, you need to install AOM-SEE-X2C or AOM-SEE-X2F switched.
