SG200-18 periodically loses connection

[Ali08437]

Hello

We have a SG200-18 Smart Switch which periodically loses connection with the rest of our network. Its data is attached.

1. a) If I put the stations on another 8 port Switch everything works ok
2. b) If the stations are switched to SG200-18 the connection although apparently active the access to the rest of the network is lost in various periods of time minutes, hours.
3. c) Switch SG200-18 worked ok at the beginning of its use, its configuration is the default one

How can we solve the problem?

 - I don't see an attachment ,but anyway followup on the logs of the switch preferably through a syslog-server which gives you the opportunity for scrutinizing and better analyzing.
