1 Sådan arbejder du med computeren Sikkerhedsinstruktioner Forudsætninger Følg sikkerhedsinstruktionerne med henblik på din egen sikkerhed og for at beskytte computeren og arbejdsmiljøet mod mulige skader. Hvis intet andet er angivet bygger hver fremgangsmåde i dette dokument på følgende forudsætninger: • • Du har læst sikkerhedsoplysningerne, som fulgte med computeren. En komponent kan genmonteres eller, hvis købt separat, monteres ved at udføre fjernelsesproceduren i omvendt rækkefølge.
FORSIGTIG: Frakobl, for at frakoble et netværkskabel, først kablet fra computeren, og frakobl det derefter fra netværksenheden. 5. Tag stikkene til computeren og alle tilsluttede enheder ud af stikkontakterne. 6. Tryk på og hold tænd/sluk-knappen nede, efter at computeren er afbrudt, for at skabe jordforbindelse for systemkortet.
• • • • Brug en kablet ESD-håndledsrem, der er korrekt jordet. Brugen af trådløse antistatiske remme er ikke længere tilladt. De giver ikke tilstrækkelig beskyttelse. Det giver ikke tilstrækkelig ESD-beskyttelse af dele med øget følsomhed over for ESD-skade, at du rører ved chassis, inden du håndterer delene. Håndter alle statisk følsomme komponenter i et statisk sikkert område. Brug antistatisk gulv- og bordbelægning, hvor det er muligt.
