How can I see the specs of how much heat my switch will generate

Hi all

We are adding some equipment to a new site where we will be adding a few Cisco Catalyst 2960S-24TS-L Switch's, they have asked us how much heat each switch will produce how or where can I find this? I had looked under the spec on :

But unable to find the information, help would be great. Ta

Hey to see what its running at you can use below command

sw>sh env all
FAN is OK
TEMPERATURE is OK
Temperature Value: 26 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 50 Degree Celsius
Red Threshold    : 60 Degree Celsius
SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts
--  ------------------  ----------  ---------------  -------  -------  -----
 1  Built-in                                         Good
 2  Built-in                                         Good

SW  Status          RPS Name          RPS Serial#  RPS Port#
--  -------------   ----------------  -----------  ---------
1   <>              <>
2   <>              <>

Hi Mark

 

Thanks for the quick response! so this will be the heat being forwarded out through the fan? into the "room" so to speak, is that correct?

That's the actual temp that the switch is running at currently , I don't think theres a command to tell you what its blowing out as to say but these docs may help all 2960s will be around the same in terms of output

Thanks, but it says power consumption what I should had originally said is that they are after heat dissipation, which is what I am struggling to find.

Try this

http://tools.cisco.com/cpc/launch.jsp

You can use this application to calculate the power supply requirements for a specific PoE configuration. The results show output current, output power, and system heat dissipation.

Hi Thanks for this I had checked here also but 24TS-L doesnt appear in the list under 2960s. 

That's me out of options :) maybe one of the other guys might know I cant find any other tools or data sheets that show that info

No worries Mark, thanks for the help
