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 equipment.
WARNING: To reduce the risk of injury from electric shock hazards, do not open power
supplies. Refer all maintenance, upgrades, and servicing to qualified personnel.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives, power
input modules, and the internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before
beginning any installation procedure. Improper grounding can cause ESD.
CAUTION: Always install a power input module or a power supply blank into each bay to
maintain proper airflow and cooling in the power enclosure. Improper airflow can lead to
thermal damage.
IMPORTANT: Mixing different types of power input modules in the same server might limit or
disable some power supply features including support for power redundancy. To ensure
access to all available features, all power input modules in the same server should have the
same output and efficiency ratings.
To remove the component:
If the server is using a single power input module only, remove all power from the server:
1.
Back up all server data.
