If you are installing multiple servers or other components in the rack, place the server so
that you can easily open and service it. For example, in a multiple-component installation,
the heaviest items—such as an uninterruptible power supply—are usually placed at or
near the bottom of a rack; servers are often located near the middle of the rack.

For a rack with multiple components, you may want to prepare a list of all equipment in
the rack and the requirements for each unit. Such a list should include the following
information:
Electrical Power
If you plan to install the server in a rack that contains other components, be sure that the
circuitry and power connections are sufficient for the combined power needs of all
components. To plan for safe and adequate power to the server, follow these guidelines:
m
Check the documentation for all components in the rack to determine their power
requirements. Also determine that the available power supply for the rack is sufficient for
the planned components.

Important
When planning for electrical power, make sure you have more power than
specified for all components. Also make certain that the power load is distributed evenly
among circuits to the rack’s location. Consult an electrician or other expert if you need
