Redundant power supply option

Install a second power input module to improve power efficiency and enable power redundancy.

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.
