47、2 11. MCP9350i Hardware Tests 11. Hardware Tests 11.1. Introduction The purpose of the hardware tests is to guarantee the correct functioning of all hardware modules. There are three cases: 1. The cause of the hardware problem is known. Run the appropriate test to confirm that the cause of the probl

48、em is correct. Swap the failing module with one from the repair kit. Run the test again. For swapping: swap the cheapest component first (e.g. cables, riser boards), then the modules and finally the motherboard. 2. The cause of the problem is not known. Start with the first test (see below) and continue until one of the tests fails. Then swap the failing module, etc. 3. None of the tests identifies a failing module. If the technician suspects that the problem is not covered by the tests, he can create his own test. Otherwise, the prod
