    Stand-bystand Dell producten met stand-bystand moeten worden losgekoppeld voordat u de behuizing opent. Systemen die zijn uitgerust met de stand- bystand worden in wezen gevoed wanneer deze uit staan. Door de interne voeding kan het systeem op afstand worden ingeschakeld (Wake on LAN) en onderbroken in een slaapstand en heeft andere geavanceerde functies voor energiebeheer.

    • Fataal: Fatale storingen vertegenwoordigen ongeveer 20 procent van de aan ESD gerelateerde storingen. De schade veroorzaakt een onmiddellijk en volledig verlies van functionaliteit van het apparaat. Een voorbeeld van een fatale fout is een geheugen-DIMM die een statische schok heeft ontvangen en onmiddellijk een 'No POST/No Video’-symptoom genereert, waarbij een pieptoon wordt uitgezonden voor ontbrekend of niet-functioneel geheugen.

    Het wordt onderhoudstechnici aanbevolen om de traditionele bedraade ESD-aardingspolsband en beschermende antistatische mat te allen tijde te gebruiken wanneer service wordt verleend voor Dell producten. Daarnaast is het van essentieel belang dat technici de gevoelige onderdelen apart houden van alle isolatoronderdelen wanneer service wordt verleend en dat ze antistatische tassen gebruiken voor het transport van gevoelige onderdelen.

    Snelheid Momenteel zijn er vijf snelheidsmodi gedefinieerd in de nieuwste USB 3.0/USB 3.1 Gen 1-specificatie. Op basis van USB gegevensoverdracht worden ze gecategoriseerd als Lage snelheid, Volle snelheid, Hoge snelheid (vanaf versie 2.0 van de specificatie), SuperSpeed (vanaf versie 3.0) en SuperSpeed+ (vanaf versie 3.1). De nieuwe SuperSpeed+-modus heeft een overdrachtssnelheid van 20 Gbps.
  • Page 12 USB Power Delivery De specificatie USB PD is nauw verbonden aan USB Type-C. Vandaag de dag maken smartphones, tablets en andere mobiele apparaten vaak gebruik van een USB-verbinding om op te laden. Een USB 2.0-aansluiting biedt maximaal 2,5 watt vermogen. Hierdoor wordt uw telefoon opgeladen, maar dat is het wel zo ongeveer.
