and warnings in this guide.
WARNING!
CAUTION:

Standard Hardware and Upgrades

To reduce the risk of personal injury from electrical shock, hot surfaces, or fire:
Disconnect the power cord from the wall outlet and allow the internal system
components to cool before touching.
Do not plug telecommunications or telephone connectors into the network
interface controller receptacles.
Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
Plug the power cord in a grounded (earthed) outlet that is easily accessible at all
times.
Static electricity can damage the electrical components of the computer and/or
optional equipment. Before beginning these procedures, ensure that you are
discharged of static electricity by briefly touching a grounded metal object.
When the computer is plugged into an AC power source, voltage is always
applied to the main board. You must disconnect the power cord from the power
source before opening the unit to prevent damage to internal components.
