Show power usage for devices

[jwbensley]

Is there anyway I can see the power usage on either a 3550 switch and/or 7301 router? I have some far away I wish to see the usage off.

Devices with module power supplies like cat 4500s/6500s/7600 etc all have commands like "show power ...", which will show me input voltage, current and power usage in watts. Is there anything like this for devices without module power supplies?

Hi,

I think the closest command that you can try is "show env power" or "show env all". Although I didn't get much information from our own 3560.

3560#sh env all

FAN is OK

TEMPERATURE is OK

SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts

--  ------------------  ----------  ---------------  -------  -------  -----

1  Built-in                                         Good

SW  Status          RPS Name          RPS Serial#  RPS Port#

--  -------------   ----------------  -----------  ---------

1   Not Present     <>

I hope this helps.

Sadly that doesn't seem to be very useful on a 3550 or 7301. I know these platform are bit old but there are many of them out there in the wild still churning away. Bit of a shame they can't do something I would consider basic, to show their own power usage. Still thanks for the suggestion!

3550#show env all

FAN is OK

TEMPERATURE is OK

POWER is OK

RPS is NOT PRESENT

7301#show environment all

Thanks Jonathan,

I the commands also work on 9200

Just replying here because this was the first thread that popped up when I did a search for finding power draw in Cisco devices.

On my UBR 10K, I had to do a show env to get my power draw as below:

you can use.

show power
show environment

Hi everyone,

Please try show power inline
