2.7 Environmental and Power Specifications
2.7.1 System Monitoring
The IEM-LX-800 is capable of self-monitoring various aspects of its operating status
including:
CPU, chipset, and battery voltage, +3.3V, +5V, and +12V
RPM of cooling fans
CPU and board temperatures (by the corresponding embedded sensors)
2.7.2 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the IEM-LX-800 are listed below.
Minimum Operating Temperature: 0ºC (32°F)
Maximum Operating Temperature: 60°C (140°F)
A cooling fan and heat sink must be installed on the CPU. Thermal paste must be
smeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinks
are also mounted on the Northbridge and Southbridge chipsets to ensure the operating
temperature of these chips remain low.
2.8 Power Consumption
Table 2-3 shows the power consumption parameters for the IEM-LX when an AMD Geode
LX 800 CPU is running with a 333MHz, 256MB DDR RAM module.
