C9500 Power Consumption

[RKK1]

Hi Teck People, 

I could not find the power calculator for C9500 from Cisco. Is there any documentation to know the actual power consumption of Cisco C9500-48Y4C with Redundant Power Supplies (650AC).

From Cisco 9500 hardware installation 

The power supplies can work together in Redundant Mode, in which each power supply operates at approximately 50 percent of its capacity

Thanks in advance.

Greetings. 
I don't have an exact answer however I can leave you with the following

I would estimate the idle power use would be in the 100-150W range with optimal conditions. Power consumption will vary based on numerous factors. I have a handful of Y4YC and 40X platforms I can look once I am at my office to give a general range.

Hello RKK1

The actual power consumption depends on, how switch is utilized and it would vary time to time, for instance when all switch ports are active and passing traffic that time power consumption would be higher. In another case when switch ports are not active during non-business hours that time power consumption would be low.

You can figure out, only max value of power consumption. In redundant mode each power supply operates 50%, which gives max value of operative power consumption.

Good morning,

The details are a bit skewed here but here is the output of "show platform hardware chassis power-supply detail switch 1 all"

PS1:
Input Voltage : 123.0000 V
Output Voltage : 12.0250 V
Input Current : 0.6070 A
Output Current : 5.2100 A
Input Power : 79.0000 W
Output Power : 62.6875 W
Temperature 1 : 27.8430 C
Temperature 2 : 36.2500 C
Temperature 3 : 30.6560 C
Fan Speed 1 : 8672.0000 RPM
PS2:
Input Voltage : 123.3750 V
Output Voltage : 12.0110 V
Input Current : 0.6710 A
Output Current : 5.7810 A
Input Power : 86.2500 W
Output Power : 69.3750 W
Temperature 1 : 27.1250 C
Temperature 2 : 39.8120 C
Temperature 3 : 31.9370 C
Fan Speed 1 : 8384.0000 RPM

This output is for a C9500-24Y4C with 4 40G QSFPs, and a handful of 10G SFPs. 

This is the output of another 24Y4C with about half of the ports in use:

PS2:
Input Voltage : 119.5000 V
Output Voltage : 12.0350 V
Input Current : 1.0580 A
Output Current : 9.5460 A
Input Power : 128.7500 W
Output Power : 114.8750 W
Temperature 1 : 16.0000 C
Temperature 2 : 26.1870 C
Temperature 3 : 24.1560 C
Fan Speed 1 : 8640.0000 RPM

As indicated previously- it will be difficult to estimate total power consumption as temperature (how fast the fans will need to spin), modules used, and other factors will all impact the power utilization. If you are looking at power capacity planning I would plan for the max output of the power supply itself as utilization could spike periodically and it would be better to have power available than not enough.

Just to add some data to @stephan.l.martin1 post.

This is a C9500-48Y4C working as an aggregation switch for our WAN.
