22 Chapter 2 Preparing to Install Your Server

• To provide access to the server’s back panel and cables, leave at least 24 inches clear

behind the server.

• 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:

• 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.

• If you need assistance in determining the power needs of the components in the

rack, consult an electrical expert who is familiar with your facility.

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 assistance with planning for the power needs of your

components.

• Make sure that the power connections for the server and all other components are

grounded (according to local and national standards). Consult an electrician if you

need assistance with grounding.

• See Appendix A, “Specifications,” for more information about electrical power

requirements for the server.

• This model is certified only as a component for use with other equipment, where the

suitability of the combination has been determined by a Nationally Recognized

Testing Laboratory.
