Can anyone shed some light on how to estimate power draw on N7K when all interfaces are up on a module? Here's an output from my n7k:
show environment power Power Supply: Voltage: 50 Volts Power Actual Total Supply Model Output Capacity Status (Watts ) (Watts ) ------- ------------------- ----------- ----------- -------------- 1 N7K-AC-6.0KW 660 W 6000 W Ok 2 N7K-AC-6.0KW 589 W 6000 W Ok 3 N7K-AC-6.0KW 620 W 6000 W Ok Actual Power Module Model Draw Allocated Status (Watts ) (Watts ) ------- ------------------- ----------- ----------- -------------- 1 N7K-M148GT-11 N/A 400 W Powered-Up 2 N7K-M148GT-11 N/A 400 W Powered-Up 5 N7K-SUP1 N/A 210 W Powered-Up 6 N7K-SUP1 N/A 210 W Powered-Up 7 N7K-M148GS-11 247 W 400 W Powered-Up 10 N7K-M108X2-12L 471 W 650 W Powered-Up Xb1 N7K-C7010-FAB-1 N/A 60 W Powered-Up Xb2 N7K-C7010-FAB-1 N/A 60 W Powered-Up Xb3 N7K-C7010-FAB-1 N/A 60 W Powered-Up Xb4 xbar N/A 60 W Absent Xb5 xbar N/A 60 W Absent fan1 N7K-C7010-FAN-S 116 W 720 W Powered-Up fan2 N7K-C7010-FAN-S 116 W 720 W Powered-Up fan3 N7K-C7010-FAN-F 11 W 120 W Powered-Up fan4 N7K-C7010-FAN-F 11 W 120 W Powered-Up N/A - Per module power not available Power Usage Summary: -------------------- Power Supply redundancy mode (configured) Redundant Power Supply redundancy mode (operational) Redundant Total Power Capacity (based on configured mode) 9000 W Total Power of all Inputs (cumulative) 18000 W Total Power Output (actual draw) 1869 W Total Power Allocated (budget) 4250 W Total Power Available for additional modules 4750 W Side A is connected to power grid Side B is connected to UPS The switch is not in production yet and there are only a few interfaces connected and in up state. If I turn off power grid, the UPS shows load increase from 40% to 80% (there are two Nexus 7000 switches on UPS) I'm worried that UPS won't be able to handle the load when all interfaces are up and if power grid fails. I would like to estimate how much additional A/W will be drawn if all interfaces on modules 1, 2, 7 and 10 are up and connected. I would like to use this information to determine if we need to upgrade our UPS.

Hi Roman,
Check power requirement chart @ http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9402/ps9512/Data_Sheet_C78-437759.html
, or use power calculator to estimate power with fully populated modules.
