How to Identify Power Consumption for your Adaptive Security Appliance.
First: The security license version, whether it be K8 or K9 has no implication on Power Consumption.
You can find your answer to this question in a couple ways:
1. https://www.cisco.com/c/en/us/products/security/asa-5500-series-next-generation-firewalls/data_sheet_c78-345385.html
a. Go to Link above, then scroll down till you come to the chart listed Power under the Specifications list.
b. Check the left side of the chart for your specification for the 5510 appliance(the 5510 is to the right of the 5505 and requires a little more power consumption that isn't listed).
NOTE: The listing is does not actually show you the answer, more of a ballpark range since you have to add more power consumption than the 5505.
2. From The Back of your ASA.
a. Check for a small bit of text beside your power plug on your ASA and it should show your the Voltage, Amperage, and Hz Range.
b. From that amount of information you can figure up exactly what wattage power supply you have.
c. Checking the back of my Cisco ASA 5510 displays the text "100-240v, 2.5A, 50-60Hz". To break these down:
- 100-240V, the Voltage range that the unit it is capable of accepting from your wall outlet.
~ In the United States, that number is 120 Volts.
- 2.5A, the Amperage of the Unit, Amperage is basically the Flow Control for the power coming in.
- 50-60Hz, the Hertz range that the unit is capable of accepting from your wall outlet.
~ In the United States, that number is 60Hz.
d. Using the information from above you can use the formula, "Volts x Amps = Watts."
- For mine, 120V x 2.5A = 300W, So mine would be a 300 Watt Power Supply.
Hope This Helps!
