The server slides out of the rack from the front. Be sure to leave a minimum of 36 inches 
clear in front of the server to allow room to open and service it.

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:
 
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.
 
m
 
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.
 
m
 
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.

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.
