    Chapter 3 Installation Guidelines Figure 3-1. Air Flow through the System/E When the proper system is installed, internal temperature rise is typically less than 15C (27F) over ambient temperature. NOTE Hewlett-Packard recommends that the customer monitor the internal temperature of the rack.
  • Page 17: Stability

    Chapter 3 Installation Guidelines Stability For stability, the sum of the moments above the 32 U critical height must be less than the sum of the moments below the 32 U critical height. As long as the weight above critical height is less than the weight below, the moments will most likely cancel.
  • Page 18 Chapter 3 Installation Guidelines As you can see from illustration on 3.3, 1.25 m racks are “unconditionally” stable, and 1.6 m racks are very difficult to overload, as they extend only 1 U above the critical height. For 1.6 m and 1.96 m racks, add the weights of the units which have centers of gravity above 32 U, then compare the sum of the weights below 32 U.
