System warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
WARNING:
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against
it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends
from the server.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: Do not operate the server for long periods with the access panel open or
removed. Operating the server in this manner results in improper airflow and improper cooling
that can lead to thermal damage.
