Removal and replacement procedures 28
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.
