PCIE-8120 Installation and Use (6806800R89C) 71
These sensors measure the PCB component temperature, which allows to determine the
absolute and the delta temperature level on the card. A possible sensor fault or a cooling
system degradation can also be indicated.
 Sensor type is a LM75 Device.
 I2C address: 0x90 for air inlet temperature sensor.
 I2C address: 0x92 for air outlet temperature sensor.
The PCB component temperature may not be very closely correlated to the system or card
ambient temperature as specified in
Table 3-1 on page 27 .
The PCB component temperature is largely dependent on specific mechanical and thermal
conditions in the respective server where the card is installed. See,
Sensor Alert Default Values
on page 73 .
