2. Chapter 5 Rack Installation 5 1 Overview This chapter provides a quick setup checklist to get your chassis up and running Following these steps in the order given should enable you to have the system operational within a minimal amount of time 5 2 Unpacking the System You should inspect the box which the chassis was shipped in and note if it was damaged in any way If the chassis itself shows damage you should file a damage claim with the carrier who delivered it Decide on a suitable location for the rack unit that will hold your chassis It should be situated in a clean dust free area that is well ventilated Avoid areas where heat electrical noise and electromagnetic fields are generated The system needs to be placed near a grounded power outlet Be sure to read the Rack and Server Precautions in the next section 5 3 Preparing for Setup The box your chassis was shipped in should include two sets of rail assemblies and the mounting screws needed for installing the system into the rack Also included is an optional square hole to round hole converter bracket for use in racks with round mounting holes P ease read this section in its entirety before you begin the installation procedure outlined in the sections that follow Choosing a Setup Location Leave enough clearance in front of the rack to enable you to open the front door completely 25 inches Leave approximately 30 inches of clearance in the back of the
