Installing AC Power
AC Power in the IGX 8410 Node
Tip To develop the most accurate IGX power budget, use Table 2-1 on page 2-1 and Table 2-2 on page 2-2
or the interactive power worksheets. If you decide to use the general guidelines mentioned in this section
during network planning stages, confirm your results by using the power worksheets before bringing the
node live in an operational environment.
For an IGX 8410 node to use an AC power source, an AC power supply system is necessary. The
IGX 8410 power supply housing holds up to four 400-watt (W) power supplies. The AC system provides
the system with –48 VDC from 100 to 240 VAC input. The AC power supply housing is between the
card cage and the side wall of the node. The IGX 8410 node has one or, with AC redundancy, two AC
power inputs. Figure 2-9 shows two AC inputs.

The minimum requirement for an AC-powered system is one AC source and one power supply. One
supply is adequate for four cards unless you specify power supply redundancy.
