Power Consumption for ASA-5555 with FirePOWER ?

[waheedullah Bahaduri]

Hi,

Can anyone tell me what is the power usage for the Cisco FirePOWER ASA-5555 series ?

I searched datasheets, couldnt find exact info.  

Thanks

The hardware installation indicates there are dual 450W power supplies.

The data sheet indicates 90W steady state output, 134W peak. Heat output is 458 BTU/hr.

Hi Marvin

does it mean each single ASA-5555 with Firepower power-supplies total capacity is 900W ?

Not really.

The power supplies are both online but either one can power the entire unit.

The appliance will never draw more than the cited output of power whether there is/are one or two power supplies active.
