SECTION 4KSU POWER-BASED CALCULATOR CHART
The Card Calculator on the next page allows you to determine the maximum power
consumption for the Power supply in each cabinet under the following conditions:
J
Each basic cabinet can contain a maximum of 10 cards.
J
Each expansion cabinet can contain a maximum of nine cards.
J
The total point value cannot exceed 1000 points for +5V.
J
The total point value cannot exceed 1000 points for -24V.
To calculate the two values (+5V and -24V) for a card:
1. Pick the card type in the chart below.
2. Calculate the +5V total point value by multiplying the number of cards by
the +5V value in the chart.
3. Calculate the -24V total point value by multiplying the number of cards by
the -24V value in the chart.
An example is shown below:
J
+5V
Five ESIB(8)-U10 ETUs multiplied by a table value of 21 is 105 points toward a
possible 1000 (895 points remaining).
J
-24V
Five ESIB(8)-U10 ETUs multiplied by a table value of 83 is 415 points toward a
possible 1000 (585 points remaining).
