Responsibilities

• Develop and maintain a full understanding of the design and operating principles of thermal and fluid cooling systems for AI and other server racks.
• Become familiar with and be able to operate In-Row and In-Rack Coolant Distribution Units (CDUs) to pump PG25 cooling liquid to racks and trays.
• Operate CDUs and change operating parameters to meet operation and test needs.
• Assemble liquid connections to house chilled water (primary cooling loop) and to racks (PG25 in secondary cooling loop).
• Test flow, pressure, and temperatures to confirm operating parameters.
• Participate in monitoring and sustaining these units.
• Interpret customer specifications and write thermal test plans.
• Use cooling equipment with operating AI equipment to simulate field operation.
• Evaluate cooling performance over a wide range of parameters.
• Report the thermal and fluids handling performance of Devices Under Test (DUTs).
• Use lab instruments and sensors to measure and record data.
• Use test data of measured variables to calculate results for the exact performance parameters being investigated.
• Provide support to other groups testing mechanical and electrical and performance for equipment on the test floor.
• Be aware of the requirements of other groups who will run tests on equipment, and ensure thermal support such as a chilled water supply at the required flow rate and temperature.
• Assemble test stands, select telemetry, install sensors, operate data acquisition equipment, and perform computer logging of data.
• Learn thermal simulation software tools and be able to extract expected performance from simulation models.
• Use scripts to extract data from the DUT computer system for use as thermal test data.
• Report the thermal capability of the design to achieve product specifications.
