Make a note, while disassembling the computer, of the locations and connections
of the various components, cards, and cables. This will make assembly easier.
Take your time, making sure to follow the instructions closely. Many problems
can occur from hurried assembly.
Make sure all cables and connectors are securely fastened.
Make sure cable connectors are properly attached to sockets. Attaching a
connector backwards could cause improper card or component operation.
Before securing an FRU or other components, make sure cables will not be
pinched by screws or the FRU.
When replacing side panels, make sure cables are tucked inside the computer's
chassis to avoid damaging the cables.
Make sure all latches are securely closed.
When assembling the computer, make sure to use the correct screws to secure the
various components, and make sure all screws are securely fastened. Loose
screws can cause short circuits, resulting in heat, smoke, and fire.
Make sure the correct screws are used to secure all FRUs and other computer
parts. Using the incorrect screws could damage the threads or the head of the
screws, resulting in improper seating of the screw. Refer to Table 4-1 for a listing
of screw sizes and quantities for each FRU and computer part.
