5 2.0 Description of Equipment Under Test (EUT) 2.1 Industrial Computer The Industrial Computers are computer server systems in individual aluminum rack-mount chassis Configuration As Tested For this testing project, the customer provided the Industrial Computer test sample #1 (part/model number IS100) with serial number , test sample #2 (part/model number IS200) with serial number , test sample #3 (part/model number IS300) with serial number The Industrial Computer test samples were tested in the configuration provided by the customer. Test sample #1 measures approximately 19 inches wide 22 inches long 1.75 inches thick, excluding all cables and/or connectors. Configuration information provided by the customer is shown in Table 3, on the next page. The customer provided the weight of the test sample as pounds. Test sample #2 measures approximately 19 inches wide 22 inches long 3.5 inches thick, excluding all cables and/or connectors. Configuration information provided by the customer is shown in Table 4, on the next page. The customer provided the weight of the test sample as pounds. Test sample #3 measures approximately 19 inches wide 22 inches long 5.25 inches thick, excluding all cables and/or connectors. Configuration information provided by the customer is shown in Table 5, on the next page. The customer provided the weight of the test sample as pounds. NCEE Labs made no modifications, adjustments, or repairs to the Industrial Computer test samples prior to, during, or upon the completion of the testing documented herein. Page 5 of 15

8 3.1 Operating Temperature Test Test Description The test samples were placed inside an environmental test chamber. Supplementary equipment necessary to operate and/or monitor the test samples (i.e. computer monitor, keyboard, & mouse) was placed on a table nearby the environmental test chamber, and connected to each test sample via a port in the side of the environmental test chamber. The customer placed the test samples into their operating state by supplying power to the test samples and allowing each test sample to complete its boot-process. The computer program Prime95 was then launched on each test sample, and setup to operate on the maximum number of simultaneous threads supported by the processor in each test sample. The computer program Real Temp was launched to monitor CPU temperature(s). Windows Task Manager was used to verify that the CPU usage was 100% on each thread supported by the processor in each test sample. The environmental test chamber control system was programmed to perform the temperature cycle described below 4 times for a total test duration of 24 hours. a) Ramp from 25 C ± 2 C to 55 C ± 2 C in 19 minutes ± 1 minute. b) Dwell at 55 C ± 2 C for 2 hours ± 1 minute. c) Ramp from 55 C ± 2 C to -40 C ± 2 C in 60 minutes ± 1 minute. d) Dwell at -40 C ± 2 C for 2 hours ± 1 minute. e) Ramp from -40 C ± 2 C to 25 C ± 2 C in 41 minutes ± 1 minute. Prior to the start of this testing, periodically during the performance of this testing, and upon the completion of this testing, each test sample was monitored for proper operation by visually inspecting its computer monitor to verify that the computer program Prime95 was operating on all threads, the CPU usage reported by Windows Task Manager was 100% on all threads, and the CPU temperatures were not causing the CPU to throttle itself.

9 3.1.2 Test Results The Industrial Computer test sample with serial number was subjected to the Operating Temperature Test described in section of this test report. The test sample was monitored for proper operation prior to the start of this test, periodically during the performance of this test, and upon the completion of this test. No operational issues were observed prior to the performance of this test, during the performance of this test, or upon the completion of this test. A visual and auditory inspection was performed upon the completion of this test. No obvious physical issues (cracks, panel separation, etc.) or audible defects (i.e. rattling) were observed upon the completion of this test Representative Photographs Representative photographs of this test begin on the next page.
