• moduł DIMM, który uległ wstrząsowi elektrostatycznemu i generuje błąd dotyczący braku testu POST lub braku sygnału wideo z sygnałem dźwiękowym oznaczającym niedziałającą pamięć. Przejściowe — takie sporadyczne problemy stanowią około 80 procent awarii związanych z wyładowaniami elektrostatycznymi. Duża liczba przejściowych awarii oznacza, że w większości przypadków nie można ich natychmiast rozpoznać.
• ekranowane. Części należy zawsze trzymać w ręce albo umieścić na macie antystatycznej, w systemie lub wewnątrz torby antyelektrostatycznej. Transportowanie wrażliwych elementów — elementy wrażliwe na wyładowania elektrostatyczne, takie jak części zamienne lub zwracane do firmy Dell, należy bezpiecznie transportować w torbach antyelektrostatycznych.
2 Technologia i podzespoły Niniejszy rozdział zawiera szczegółowe informacje dotyczące technologii i składników dostępnych w systemie. Tematy: • • • • • • • Funkcje USB USB Type-C HDMI 2.0 NVIDIA Quadro T1000 NVIDIA Quadro RTX3000 NVIDIA Quadro RTX4000 NVIDIA Quadro RTX5000 Funkcje USB Standard uniwersalnej magistrali szeregowej USB (Universal Serial Bus) został wprowadzony w 1996 r.
Szybkość Obecnie w najnowszej specyfikacji standardu USB 3.0/USB 3.1 pierwszej generacji zdefiniowanych jest pięć trybów szybkości. Są to (od najwolniejszego do najszybszego): Low Speed, Full Speed, High Speed (od wersji 2.0 specyfikacji), SuperSpeed (od wersji 3.0) i SuperSpeed+ (od wersji 3.1). Nowy tryb SuperSpeed+ ma szybkość przesyłania danych 20 Gb/s. Standard USB 3.2 jest zgodny z wcześniejszymi standardami USB 3.1/3.0 i USB 2.0. Znacznie wyższa wydajność złącza USB 3.
USB Power Delivery Specyfikacja USB PD jest ściśle związana ze standardem USB Type-C. Współczesne smartfony, tablety i inne urządzenia mobilne często są ładowane przez złącze USB. Połączenie USB 2.0 zapewnia moc do 2,5 W, co wystarcza do naładowania telefonu, ale nie pozwala na zbyt wiele poza tym. Na przykład notebook może wymagać mocy nawet 60 W. Specyfikacja USB Power Delivery zapewnia moc nawet 100 W. Przesyłanie energii jest dwukierunkowe: urządzenie może zasilać inne urządzenia lub pobierać energię.
Kluczowe cechy połączenia Thunderbolt 3 przez USB Type-C 1. Thunderbolt, USB, DisplayPort i zasilanie za pomocą gniazda USB Type-C z użyciem jednego kabla (funkcje mogą się różnić między produktami). 2. Złącza i kable USB Type-C są kompaktowe i można je podłączać w dowolnym położeniu. 3. Obsługa łączenia urządzeń w sieć za pomocą interfejsu Thunderbolt (*może się różnić między produktami). 4. Obsługa wyświetlaczy o maksymalnej rozdzielczości 4K. 5.
• HDMI łączy obraz i wielokanałowy dźwięk w jednym kablu, eliminując wysokie koszty i komplikacje związane z wieloma kablami stosowanymi w systemach A/V. HDMI obsługuje komunikację między źródłem wideo (takim jak odtwarzacz DVD) a telewizorem DTV, zapewniające nowe możliwości. • NVIDIA Quadro T1000 Tabela 2.
