Hi Friends, Today we will see how to Flash Ultranet OLT. For this we need some tools and files i.e. TFTP, Putty & Flashing Firmware File.<br /><br />You can buy OLT from Distributor directly click bellow link<br />https://ultratech.pk/<br /><br />1st we will connect Photon OLT with Laptop Using NMS or Console both ports, then we will give manual IP in Laptop / PC. IP is ( 192.168.1.167) then open Putty using speed 115200 (Note: verify your COM port). After that we will open TFTP server and select IP then select Directory where our Flashing Software was place. <br />Now we will run this command in Putty: run upt:app<br />(Note: Turn OFF PC / Laptop firewall.)<br />We can see TFTP Server transfer the file and flashing procedure is start. we will wait for a while then we will Reboot the OLT.<br />Our OLT is successfully Operational.<br />Thanks for watching my video.<br /><br />~' " "~
