The fans are installed on the left side of the chassis for heat dissipation.
The MA5606T has four board slots, of which:
!
Slot 0 is located on the upper left side of the chassis. It houses the power supply board.
!
Slot 1 is located on the upper right side of the chassis. It houses the main control board.
!
The main control board is wider than the power supply board. This helps to avoid
mis-insertion.
!
The service board is wider than both the main control board and the power supply board.
This helps to avoid mis-insertion.
!
The number of service and splitter (SPL) boards to be configured depends on the service
types and traffic volumes.
