*The typical power consumption values represent typical traffic, load and line speed of the CoreBuilder and interface cards. Maximum power consumption of the cards is 10% higher than the typical values, and occurs when all card ports are working at full rate

† A redundant switch has the same power requirements as the active switch

Required Power Table 7-3, which is calculated from Table 7-2, shows the number of Supply for Various power supplies required (Single or Dual) for various CoreBuilder 7000

CoreBuilder installations. The first column describes the particular combination of Installations cards installed and covers the most common applications. The second column shows the number of power supplies required if a redundant switch is not installed; the third column shows the number of power

supplies required if a redundant switch is installed.
