Is the Huawei MA5683T end of life?

The only difference is capacity, MA5683T max support 6 service slots, MA5680T max support 16 service slots. So MA5683T with smaller chassis.

Huawei MA5603T is multi service based while MA5683T is just OLT, MA5603T can support service like ADSL, VDSL, GPON etc, while MA5683T only supports GPON, P2P etc, but their hardware and configuration command is the same. The same as MA5680T and MA5600T.

You can change mac-address of SCUB on Huawei OLT MA5680T in following way:
1. First you have to login as root user
2. You will have to enter in diagnose mode with following commands:
huawei(config)#diagnose
huawei(diagnose)%
3. you have to check which mac address is currently in the system by command:
huawei(diagnose)% display sysman mac-address
Current MAC address of active mainboard: 0025-1c54-c45c
Default MAC address of active mainboard: 0025-1c54-d0763
4. Changing mac-address you can done with command:

5. Last step is to reboot board on which you have change mac-address or to reboot system. In this way new mac-address will be applied to the SCUB board
