6.2.2.7 Hardware
The Status > Hardware screen shows the current detected temperature at each FRU slot, temperature
limit information per device, and the ambient temperature of the power board. The system voltages at
various points on the board are also displayed along with all USB devices connected to the system and
any mounted memory devices.

Temperatures and Limits
The hysteresis values are used when FRUs start to return to the normal temperature range. The high
limit represents the upper temperature at which the FRU will be powered off until the temperature drops
to (High Limit - High Hysteresis). The heater limit represents the temperature at which the heater will start
warming the FRU until the temperature increases to (Heater Limit + Heater Hysteresis). The low limit is
the lower temperature at which the FRU will be powered off until the temperature increases to (Low Limit
+ Low Hysteresis).
Power board:
Sensor located on the power board and represents the ambient temperature inside the
box.
FRU#:
Sensor located beneath the FRU slot and represents an estimation of the FRU temperature.
System Voltages
The voltages at various points along the board are displayed including system voltage, USB voltage, and
voltages across multiple super capacitors.
