Random reboots on 3/3 and Cisco support is aweful
This thread convinced me that it's a design flaw and not just me: https://supportforums.cisco.com/discussion/12458991/sg220-port-down-and-port-has-not-finish-rtct-yet Also note: Don't buy Cisco products.
The features of these switches are nice
We bought three of these from two different vendors; All three are randomly rebooting every few days; Sometimes more often, sometimes less often; They have a limited lifetime warranty, but I'm pretty sure Cisco's support is paid to run you around until you give up
