Dear 

i want ask how install last SW in olt & mini olt MA5600T, whit command to config mini olt uplink card capacity 1GB only no 10GB 

You can downgrade the software to the last version by loading the combined package file and database

1.         Run the load packetfile command to load the combined package file of the last version.

2.         Run the load data command to load the backup database of the last version.

3.         Run the reboot system command to reset the system.

And, what do you mean of "whit command to config mini olt uplink card capacity 1GB only no 10GB "? If you want to set the transmission rate of the Ethernet port, you can use the command speed.
