Netgear GS110TPv3 port disabled automatically regularly

Hello,

I have recently purchased NegGear GS110TPv3 switch for ISP connectivity. 

Below is the setup How I throught he cable routing:

     i.  I took the output from POE Adaptor(ISP) to NetGear switch Port-1.

    ii.  And I took output from Port-10(SFP Port) to Fortigate firewall input.

 

when the connection is established network transaction is good through NetGear switch Port-1. After some few minutes or Few Hours the particular port gets disabled automatically.

I tried below steps for troubleshooting but not works.

i. Port configuration ==> Duplex Mode ==> Full.

ii. Port Configuration ==>  Admin Mode ==> Enable.

 

Kindly check the logs generated on switch:
