All productsHuawei MA5800 series OLT includes MA5800 X2, MA5800 X7, MA5800 X15 and MA5800 X17, except for MA5800 X2, X7 X15 and X17 control boards are universal. H901MPSC and H901MPSA are MA5800 X2 control board; MA5800 X7 X15 X17 control boards are H901/902/903MPLA and H901/902MPLB. Control boards with different versions have different functions, but all control boards support the following functions:
- Active/standby switchover on the control plane
- Load balancing on the forwarding plane
- Local and remote maintenance through the management serial port (CON) or management Ethernet port (ETH)
- Environment monitoring through serial port ESC
For MA5800 X2 control board H901MPSC/H901MPSA, management and environment monitoring can share the same serial port.
Below is a detailed comparison list of Huawei MA5800 OLT control board, “Yes” indicates “supported” and “No” indicates “not supported”.
