4.15.1 Service Processor Interrupts
The P2020 provides a programmable interrupt controller with up to twelve interrupt request
inputs with programmable polarity and sense of each signal. Only interrupt inputs IRQ[6:0] are
used on ATCA-9405.
The following table lists all interrupt sources of the Service Processor domain and how the
interrupts are routed on the board.
4.16 Cooling
A passive heat sink is mounted on top of the P2020 package. The heat sink is designed to
withstand shock and vibration tests according to the environmental considerations. The heat
sink keeps the processor die temperature below the maximum rating of 125°C under any
conditions listed in
Environmental Considerations on page 53 .
