4.17.1 Reset Sequence
The timing of the reset sequence supports each chip reset requirements with respect to the
power supply.
4.18 Thermal Management
The MVME2500-ECC utilizes two on-board temperature sensors: one for the board and the
other for the CPU temperature sensor. The board temperature sensor is located near the dual
RJ45 connector near the front panel. The CPU temperature sensor is located near the P2020
CPU.
The MVME2500-ECC thermal management support will interrupt the process only to show the
current board and CPU temperature. This interrupt is routed directly to one of the processor’s
IRQ4.
The table below shows the low and high threshold temperature in order for the interrupt to be
asserted.
