Installing System Components

Safety Measures

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized is not covered by warranty. Read and follow the safety instructions that came with the product.

System components and electronic circuit boards can be damaged by discharges of static electricity. Working on systems that are still connected to a power supply can be extremely dangerous. To avoid injury to yourself or damage to system, follow these guidelines:

If possible, wear a grounded wrist strap when you are working inside the system chassis. Alternatively, discharge any static electricity by touching the bare metal chassis of the system chassis, or the bare metal body of any other grounded appliance.

Hold electronic circuit boards by the edges only. Do not touch the components on the board unless it is necessary to do so. Do not flex or stress the circuit board.

Leave all components inside the static-proof packaging until you are ready to use the component for the installation.
