The OSN2500 SSQ2SAP veneer board is available in two functional versions, Q1 and Q2. The main difference between the two versions is the different indicators on the panel. the Q1SAP veneer board has been discontinued. The single board is the system auxiliary interface board, which is applied in the OptiX OSN system to provide various management interfaces and auxiliary interfaces. The single board provides various management interfaces and debugging interfaces, etc. for the system, and provides centralized backup of +3.3V power supply and other functions for each single board of the subrack. The single board consists of overhead processing module, system communication module and power monitoring module. The single board has jumpers that can be used to set the input voltage used by the equipment and to test the official telephone. The single board can be inserted in slot 14 of the subrack. failure of the SAP single board causes the PIU single board to falsely report the POWER_ABNORMAL alarm, which can be eliminated by replacing the SAP single board.
