3 Crystal Group In-House Thermal Testing for RCS1921R Purpose This document has been created to provide an overview of the test results for the RCS1921R that Crystal Group completed in-house thermal testing on. Test Description The test sample was placed in the Thermotron Industries Model S-16 (Serial # 698/15317RF). Supplementary equipment necessary to operate and/or monitor the test sample (e.g., computer monitor, keyboard, and mouse) was placed on a table nearby the environmental test chamber and connected to the test sample. Refer to MIL-STD-810G for recommended ramp rates. System Configuration CPU MODEL: N/A TJ Max: N/A GPU MODEL: N/A RAM SIZE/QTY: N/A HARD DRIVE MODEL/SIZE: N/A Test Results Refer to Table 1 for detailed data. Operating EUT DID NOT experience obvious physical deformations (e.g., cracks, breaks, bent components, etc.) or operational issues observed during the performance of the Operating Temperature or upon the completion of the Operating Temperature Test. EUT DID experience obvious physical deformations (e.g., cracks, breaks, bent components, etc.) or operational issues observed during the performance of the Operating Temperature or upon the completion of the Operating Temperature Test. Non-Operating EUT DID NOT experience obvious physical deformations (e.g., cracks, breaks, bent components, etc.) prior to the performance of the Non-Operating Temperature or upon the completion of the Operating Temperature Test. 2 of 5

4 EUT DID experience obvious physical deformations (e.g., cracks, breaks, bent components, etc.) prior to the performance of the Non-Operating Temperature or upon the completion of the Operating Temperature Test. Why did the system fail? What didn t work? The system remained fully operational for the entire test. All ports were plugged into a switch and the functionality was tested through the console port of the router. The IOS did display a warning message at 42C, but the system remained functional at 55C. Pass Criteria is as follows: Unit performs without thermal throttling or degradation of performance due to temperature extremes. Video integrity maintained throughout testing profile. EUT remains fully operable throughout test profile. Failure Criteria is as follow: Unit does not perform without thermal throttling or degradation of performance due to temperature extremes. Video integrity is not maintained throughout testing profile. EUT does not remain fully operable throughout testing profile. Test Results Summary Thermal Testing EUT MODEL #: RCS1921R EUT SERIAL #: PASS/FAIL: PASS Storage Temp Results Hot Temp: 85C Cold Temp: -55C Pass/Fail: PASS Pass/Fail: PASS Summary: No anomalies observed after unit went through storage test. 3 of 5
