  •  Pencil

   Some of the installation procedures require two people.

•  Before you begin to install the server in the rack enclosure, review the safety and handling  guidelines specified under 'Safety Information'. These guidelines will help you work  safely while working with the server and options.
•  Review the documentation that comes with the rack enclosure for additional safety,  cabling, and operating considerations.
•  To ensure cabinet stability, install the servers starting from the bottom of the rack enclosure.

  NOTE: If you are installing different server models in the rack enclosure,  install the heaviest models in the lower part of the rack enclosure.

•  Ensure that you plan the rack enclosure installation within the guidelines for:
  •  Heat generation
  •  Electrical requirements
  •  Air flow
  •  Mechanical loading
