Power Worksheets
Fill in the blank cells in Table 2-1 using the following rules:
Step 1 For lines 1 to 19, fill in the number of cards to be installed in the Quantity column.
Step 2 Multiply the IGX card quantity by the card wattage listed in the Card Power column, and enter the result
in the Total Power column.
Step 3 Total the Quantity column and enter the result in the Total Number of Cards row (line 20).
Tip If you have an IGX 8420 or IGX 8430, remember to include the fan trays in the total number of cards.
Although fan trays are not really cards, include the power consumption of the fan trays in any chassis
power configurations.
Step 4 Confirm that the total number of cards does not exceed the allowable number of cards for your chassis.
The IGX 8410 allows 8 cards, the IGX 8420 allows 16 cards, and the IGX 8430 allows 32 cards.
Step 5 Total the Total Power column and enter the result in the Total Power Demand row (line 21).
