Cisco Hw heat Dissipation

[ahmed_saied]

dear Team,

i do have a list of Cisco products that operates in my Data center among different floor rooms. i need to calculate the heat dissipated from each unite and i cant find this figures in the HW datasheet 

• Switch Cisco catalyst  3560 – 48 port
• switch Cisco catalyst  3750 – 24 port
• switch Cisco catalyst  3560 – V2 -24 port
• Switch Cisco catalyst  3560G – 24 port
• switch  Cisco 2960  Plus series– 48 port
• Cisco ASA 5505
• Switch Cisco catalyst 3750G –wireless LAN controller 24 Port
• Router – Cisco 2800

Hi, 

Per the 13th Edition Telecommunications Distribution Methods Manual Chapter 9: Power Distribution

one watt is equal to 3.412 BTU/hr

So to determine how much heat you need to dissipate you take the total number of watts the equipment will consume and multiply that by 3.412

12,000 BTU is equal to ONE ton of cooling.

For example you have a telecommunications room with ten (10) Cisco Catalyst 2960X-48FPD-L which according to Cisco draws a maximum of 66.7 watts per unit. That is a total to 667.0 watts

To find out how much cooling would be necessary the following steps would take place:

1. 667.0 watts * 3.412 BTU/hr = 2,275.8 BTU/hr
2. 2,275,8 BTU/hr / 12,000 Tons = .18965 tons of cooling required.

You simply add at the power wattage usage for each piece of IT equipment in the room and then you can get the cooling requirement.

Hope that could help.
