When it turn on and uplink interface GE17 to core switch going to up my sg200 receives an IP address from my DHCP-server. Next, I connect the laptop to the port GE7, port change state to up, but it does not recieve any packets(even broadcast) from my network. Also all broadcast(arp-request / dhcp discover) packets sent from a laptop connected in this(or any other) port do not reach the network.
Logs says that everything fine:

Now strange thing I mentioned in the topic:
If I login to the web interface and changing any parameter (even hostname) and go to save settings(copy Runnung Configuration to Startup Configuration) -- port GE7 (and all others) are beginning to work correctly.
Reflashing didn't solve the problem, as well as changing firmware to previous version. RMA case is opened after few calls to TAC and live webex session with Cisco support assistace. Waiting for new device.
