17 Calculating Power Consumption and Heat Dissipation Calculating Power Consumption and Heat Dissipation The following procedure describes how to calculate power consumption and heat dissipation for AI120. CAUTION: Personnel handling cards must wear an antistatic wrist strap and follow electrostatic procedures. 1. Enter the following steps and make the following calculations in Table 2, Enter a 1 in the quantity field to the right of the name of the line card in the chassis. Multiply the Watts per Card by 1. Enter the amount in the Subtotals field to the right of the name of the line card in the chassis. Add the subtotal of the card and the subtotal of the chassis to obtain the total card consumption. (A value for the chassis has been added to the table.) Table 2 Calculating Total Card Consumption Card Watts per Card Quantity Subtotals x = W x = W Connect (one PMC) x = W Connect (two PMCs) x = W Extend 9.50 x = W Firewall 9.50 x = W Firewall (one PMC) x = W Firewall (two PMCs) 24.5 x = W Flex (all models) x = W Focus x = W AIwan T1/E x = W Chassis 6.90 x 1 = 6.90 W Total Card Consumption = W Page 16

18 Calculating Power Consumption and Heat Dissipation 2. Calculate the total power draw. Using Table 3, enter the Total Card Consumption obtained in Table 2. Multiply by the typical power supply loss factor at full load to obtain the total power draw in Watts. Table 3 Calculate Total Power Draw Chassis Watts Power Supply Loss Factor Total Power Draw Total Card Consumption (from Table 2) W x 1.19 = W 3. Calculate the total chassis heat dissipation. In Table 4, enter the total power draw value obtained in Table 3. Multiply the Total Power Draw by the conversion factor 3.41 to obtain the Total Chassis Heat Dissipation in Btu/Hr. Table 4 Calculating Total Chassis Heat Dissipation Total Power Draw (from Table 3) = W Conversion factor x 3.41 Total Chassis Heat Dissipation = Btu/Hr Calculating Current Draw Use the above steps to calculate the actual current that AI120 draws from the power source. Calculations are based on the Total Chassis Power Consumption (Watts), a value developed in Table 4. This total current is used by the site engineer to determine power plant capacity requirements. Calculating Actual DC Current Draw To find the actual DC current draw of AI120: Table 5 Calculating Actual DC Current Draw Total Chassis Power (from Table 3) Actual DC voltage at site Divide Total Chassis Power by actual DC voltage at site = W / W = Actual Current Page 17
