Use the information in Table 20 on page 79 and Table 21 on page 80 to calculate power consumption for
various hardware configurations, and thermal output, as shown in the following examples. These examples
use maximum values per IOC.
Typical power consumption for AC-powered services gateways:
•
Minimum AC-powered configuration:
Base services gateway (nonredundant) + 1 SPC + 1 NPC =
353 W + 139 W + 75 W = 567 W
•
Maximum AC-powered configuration:
Base services gateway (redundant) + 7 SPCs + 3 NPCs + 2 IOCs + SCM =
353 W + 7(139) W + 3(75) W + (2) 61 W + 41 W =
353 W + 973 W + 225 W + 122 W + 41 W = 1714 W
•
Typical system thermal output (based on maximally configured AC-powered services gateway @ 110 V
input):
Watts * 3.41 = BTU/hr
1714 W * 3.41 = 5845 BTU/hr
