NEC E3100 User Manual

 

 

There is hazardous voltage present inside the computer 
when it is connect to an AC supply, even when the 
computer’s power switch is off. Exposure to hazardous 
voltage could cause personal injury. To avoid risk of injury, 
contact an Authorized Service Provider for proper 
(UN)installation of optional hardware devices. 
 
 

Electrostatic electricity can easily damage circuit cards and 
integrated circuits (ICs). To reduce risk of damage, store 
them in protective packaging whenever not installed in your 
system. 
 
Add-in cards can be extremely sensitive to ESD and always 
require careful handling. After removing the card from the 
computer, place the card flat on a grounded, static-free 
surface, component-side up. Use a conductive foam pad if 
available, but not the card wrapper. Do not slide the card 
over any surface. 
 
Before you install or remove memory modules, video 
memory, disk drives, circuit cards or other devices, protect 
them from static electricity. To do so, make sure your 
computer’s power switch is OFF. Then, unplug the 
computer’s AC power cord. Before picking up the device you 
(un)install, you should wear an anti-static wrist wrap 
(available at electronic supply stores). Be sure to connect 
the wrist wrap to an unpainted metal portion of the computer 
chassis. As an alternative, you can dissipate electrostatic 
build-up by touching an unpainted metal portion of the 
computer chassis with one hand. Then touch the device you 
are (un)installing with the other hand, and maintain 
continuous contact with it until it is (un)installed in the 
computer. 
 
 

Under no circumstances should you attempt to disassemble 
the power supply. The power supply contains no user-
serviceable parts. Inside the power supply are hazardous 
voltages that can cause serious personal injury. Always 
return a defective power supply to your dealer. 

 

Ensure that the computer disconnected from its 
power source and from all telecommunications 
links, networks, or modem lines whenever the 
chassis cover is remove. Do not operate the 
computer with the cover is removed. 
 

Assurez-vous que le système est débranché de 
son alimentation ainsi que de toutes les 
liaisons de télécommunication, des réseaux, et 
des lignes de modem avant d’enlever le capot. 
Ne pas utiliser le système quand le capot est 
enlevé. 
 

Das System darf weder an eine Stromquelle 
angeschlossen sein noch eine Verbindung mit 
einer Telekommunikationseinrichtung, einem 
Netzwerk oder einer Modem-Leitung haben, 
wenn die Gehäuseabdeckung entfernt wird. 
Nehmen Sie das System nicht ohne die 
Abdeckung in Betrieb. 
 

Asegúrese de que cada vez que se quite la 
cubierta del chasis, el sistema haya sido 
desconectado de la red de alimentación y de 
todos lo enlaces de telecomunicaciones, de red 
y de líneas de módem. No ponga en 
funcionamiento el sistema mientras la cubierta 
esté quitada. 
 

Zorg er voor dat alle verbindingen van en naar 
de computer (stroom, modem netwerk, etc) 
verbroken worden voordat de behuizing 
geopend wordt. Zet de computer nooit aan als 
de behuizing geopend is. 
 

Prima di rimuovere il coperchio del telaio, 
assicurarsi che il sistema sia scollegato 
dall’alimentazione, da tutti i collegamenti di 
comunicazione, reti o linee di modem. Non 
avviare il sistema senza aver prima messo a 
posto il coperchio
