LSI 25083 manual When Working Inside Your Computer

Make sure that equipment does not rest on your computer system cables and that the cables are not located where they can be stepped on or tripped over.

Do not spill food or liquids on your computer. If the computer gets wet, consult the documentation that came with it.

Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components.

Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a rug.

When Working Inside Your Computer –

Caution: Do not attempt to service the computer system yourself, except as explained in this document and elsewhere in LSI documentation. Always follow installation and service instructions closely.

1.Turn off your computer and any peripherals.

2.Disconnect your computer and peripherals from their power sources. Also disconnect any telephone or telecommunications lines from the computer.

Performing these actions reduces the potential for personal injury or shock. Also note these safety guidelines:

When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs. If you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned.

Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component, such as a microprocessor chip, by its edges, not by its pins.
