For the test, I perform a reset on the BDCOM P3310C-2AC, and similarly can be reset on other BDCOM P3310 revisions.
We connect the console cable to the device that is turned off, open the terminal, turn on the power, immediately hold down the Ctrl + P keys, hold them and wait for the inscription to appear below, if the keys are pressed late, the device can start to boot normally, in this case we’ll start again.
I had the inscription:
Welcome to BDCOM P3310C EPON OLT
Then I pressed the “Enter” key and displayed:
Type the command:
We agree that we want to erase this file by pressing the “y” key.
Done, the configuration file is erased, it remains to reboot the device by typing:
And again we agree by pressing “y“
Watch the video as I did:
