power consumption

cmuench · ‎01-05-2012

Hello,

I have 2 x 3560e-24td-s

2 x ASA5510

2 x 2821(no modules)

2 x 2901

I'm trying to figure out power draw in Amps for my new cabinet.

I looked at the data sheet for the 2821 and it says 3A for the 110V under the row

AC Input Current

Would that be accurate if I did that for all the models and then just added up the total?

Hi Chris,

You would need to look at each device's data sheet to get more accurate number, specially if the any of your switches have POE ports.

ok.

Does the 2821 have dual power supplies so in reality does each power supply draw 1.5A?

There is only one power supply. For a 2821 without any IP phone support, it is 280W (955 BTU/hr)

See table-7 in this link:
