This appendix describes the thermal requirements for reliable operation of a ZT 5515 using the
® ®
Mobile Intel Pentium 4 Processor - M. It covers basic thermal requirements and provides
specifics about monitoring the board and processor temperature.

Thermal Requirements

The ZT 5515 is equipped with an integrated heatsink for cooling the processor module. The
maximum processor core temperature must not exceed 100° C. The heatsink allows a maximum
ambient air temperature of 50° C with 200 linear feet per minute (LFM) of airflow. The maximum
power dissipation of the CPU is 25 W at 1.2 GHz and 1.20 V.
strongly recommends the use of a fan tray below the card rack to supply the external airflow.
The "Thermal Requirements" table below shows the relationship between ambient air temperature,
board temperature, and processor core temperature.

Temperature Monitoring
Because reliable long-term operation of the ZT 5515 depends on maintaining proper temperature,
Intel strongly recommends verifying the operating temperature of the processor module and
processor core in the final system configuration.
