Huawei MA5800 OLT main control boards includes MPLA,MPLB,MPSC, MPSA and MPSG, and each board has different versions such H901 H902 H903 H905 etc. All these control boards support the following functions:
1, Active/standby switchover on the control plane
2, Load balancing on the forwarding plane
3, Local and remote maintenance through the management serial port (CON) or management Ethernet port (ETH)
4, Environment monitoring through serial port ESC
Are there any function and performance function among these board? Below table will give you an answer.

In the preceding table, the IPv4 routing table and ARP table share the same storage space, and the IPv6 routing table and the ND table share the same storage space.
H901MPLA, H902MPLA and H903MPLA are slot compatible.
H901MPLB and H902MPLB are slot compatible.
H901MPSC and H901MPSA are not slot compatible.
H901MPSC and H901MPSA,management and environment monitoring can share the same serial port.
