Dear Zhan,
Thank you for reaching the Small Business Support Community.
Unfortunately the MDS9124 is not part of the Small Business Switches family but an Enterprise device so I suggest you to inquire about this on the "LAN, Switching and Routing" community group;
https://supportforums.cisco.com/community/netpro/network-infrastructure/switching
You may also move this post from the 'Action" panel on the top right corner of this page and please do not hesitate to reach me back if there is any further assistance I may help you with.
Kind regards,
