NOTE:

1. Total Output Current - Total Output Current (amperes) allocated to the line cards and powered devices in the chassis.

Total Output Power At 40C - Total output power (P-Output) that the systems require from the power supply. From the power supply perspective, this is the power out (P-output).

Total Typical Output Power - Power used at 27C ambient temperature with 50% linerate IMIX traffic.

Total Heat Dissipation At 40C - Heat dissipation is a direct function of power used. To get heat in BTU/hr, multiply the power draw in watts by 3.41. Example the power calculator says that a given system draws 2800W. This means
the system dissipates (2800*3.41 -->9548 BTU/hr)of heat.

Percentage of Power Used is color-coded with green if the power consumption is up to 80 percent, orange if the power consumption is between 81 and 90 percent, and red if between 91 and 100 percent.

2. Output Power is the amount of power delivered from the Power Supply to the ASR 9000 router. To figure Input Power, divide output power by 0.92 (conservative typical efficiency of the power supplies).
Output Power and Heat Dissipation numbers computed by the Cisco Power Calculator are maximum values and can be used for facility power and cooling capacity planning. These figures are not indicative of the actual
power draw or heat dissipation. Typical power draw is up to 30% lower than the maximum value shown. Please contact us at asr9k-power@cisco.com for additional information.
Please note that in order to dimension the number of power supplies needed for a chassis, the 40C or 50/55C power values should be used, depending on whether the worst case ambient temperature considered
is 40C or 50/55C
3. The Power Calculator attempts to provide the power budget rules employed in the latest software releases. It does not account for changes in the power management software made in previous versions. Please consult the power
management section of the Release Notes for a history of changes to the software power management operation.
