System Power Consumption

This appendix includes power consumption information for Cisco ICS 7750 subsystem modules and for some example system configurations.

Table B-5 describes the minimum Cisco ICS 7750 hardware configuration and the power consumption for that configuration.

Table B-5: Minimum Hardware Power Consumption

Card	Power Consumption (in Watts)
System processing engine	28.1
System switch processor	15.35
System alarm processor	6.2
Multiservice route processor	19
Cooling fans	18.72
Total Watts	87.37

Table B-6 describes the remaining power available to other chassis slots in a minimum Cisco ICS 7750 hardware configuration.

Table B-6: Remaining Power in Minimum Configuration

Voltage	Used in Min. Configuration	Total Available	Available Per Slot
5.1	33.07	119.93	29.98
3.3	28.38	37.62	9.41
12.2	24.42	73.18	18.3
-12.2	1.5	10.7	2.68
Total	87.37	241.43	60.361

1Combined power for each of the four remaining slots should not exceed allowable power for the system: 28.16W.

Table B-7 describes the power and current consumption for a possible maximum Cisco ICS 7750 hardware configuration.
