7.11 Power Supply Returned for Repair
Power supplies returned to the vendor for repair, are returned for full credit.
Power supplies returned from vendor repair will be accepted by Intel only after the vendor has
performed an additional burn-in of 4 hours min. at 45°C ± 5°C at maximum load and has re-
tested the power supply following the burn-in.
The vendor shall supply failure analysis, and final test results on all repaired units reshipped to
Intel.
