Redundant Power Supply 7-5
Required Power
Supply for Various
CoreBuilder
Installations
Table 7-3, which is calculated from Table 7-2, shows the number of
power supplies required (Single or Dual) for various CoreBuilder 7000
installations. The first column describes the particular combination of
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.

*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
