Card and Electrical Protections

The MA35D card has logic to reset individual ASIC devices and to reset the card when respective reset thresholds are reached or exceeded. When a reset occurs, power to the SC will remain on, but the card will be pulled off the PCIe bus and not be detectable by the OS. A cold reboot of the server is required to recover. Warning thresholds should be used by BMC. The following table lists ASIC device thresholds and are applicable equally to both devices.

Table 1. Device Thermal and Electrical Protection Thresholds
Sensor Description	Device Reset Threshold	Device Warning Threshold
ASIC temperature	110°C	100°C
V_CCINT temperature	125°C	105°C

The following table lists the card thresholds. Card temperature is the maximum of the inlet and outlet temperatures.

Table 2. Card Thermal and Electrical Protection Thresholds
Sensor Description	Card Reset Threshold	Card Warning Threshold
3.3V PEX	3A for 1s	2.75A for 1s
12V PEX	5.5A for 1s	5.25A for 1s
Card temperature	90°C	85°C
