Why I did it 1. fix chassis test_set_fans_led case 2. fix chassis get_name case mismatch issue 3. fix fan_drawer test_set_fans_speed 4. fix component test_components test case How I did it Add corresponding configuration into chassis json file How to verify it Run platform tests cases to verify these failure cases Co-authored-by: Ikki Zhu <79439153+qnos@users.noreply.github.com>
