•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:

Component	Power	Clear area	Height	Temperature	Other
	needed	front/back	in rack	range
Server 1
Server 2
Storage

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.
