Syrotech ONT upgrade procedure

Syrotech ONT upgrade procedure

MODEL : SY-GPON-1110-WDONT

It has been observed that those ONTs which are not properly configured for security settings can be remotely accessed and a bug is sent in ONTs so that these ONTs start uploading random dummy data choking the uplink of OLT and choking ISP backbone.

Now Syrotech Networks have provided a security patch restricting remote access of this ONT model.

Below is the path for upgradation of Syrotech ONT and procedure to upgrade.

Download the latest security patch firmware from below link :

Power ON the ONT on UPS supply if possible.
Login the ONT using address http://192.168.1.1
Username admin
Password  stdONU101                        or changed password if already changed.

Then move to Management then Device Management then upgrade and then choose the downloaded file and click start.                        

Your device may get bricked if power supply fails during the process.

After the ONT is upgraded it will show below login page.

Now login the ONT with username admin and password Syro@43210$.

Update the password with something new.

Login again and you can now check updated software version.
