The H902MPLA control board is the most important part of the OLT. They provide uplinks, configuration and control. It contains the complete configuration of the OLT. It also has 4 GE/10GE ports for uplinks and CON, ETH, ESC and USB ports for monitoring and maintenance. No SFP modules included.
OLT usually has 2 H902MPLA control boards for uninterrupted operation. During normal operation, one control board is active and the other is in standby mode. In case of problems with the main board, the standby board takes over this role. Because when we set up the OLT, we need to save the configuration and data.
