Maximum power consumption vs standby or normal power. Models ASR 1002-X, ISR 4451, 5520, WS-C2960X-48FPS-L

[Zigor Larrabe]

Hello,

For the models listed in the title, when I check the datasheets, I get maximum power data but no mention of idle or standby power.

Where can I get these data?

For example, for ISR 4551 the datasheet mentions:

Typical power (no modules) (watts)	158
Maximum power with AC power supply (watts)	450 (no PoE)
Maximum power with DC power supply (watts)	437 (no PoE)
Maximum power with PoE power supply (platform only) (watts)	1000 with PoE redundant 1450 with PoE boost no redundancy
Maximum endpoint PoE power available from PoE power supply (watts)	500 W with optional redundancy
Maximum endpoint PoE power capacity with PoE boost (watts)	950 W no redundancy

Thanks.

 - How do you define standby power for these devices ?

From my limited undestanding of these networking equipment, I presume that the maximum power consumption data is when all the ports are wired and communicating traffic simultaneously at maximum speed.

Cannot we have an average power consumption value or something similar? In a computer, the power consumption depends strongly in the CPU and GPU loading.

I have more than 100 of such equipment for voice & data of a power plant and I need to get an average power consumption value.

Power consumption on the Switch, is based on the PoE devices connected. and based Switch required some power to work.

this all depends on what PoE device connected to each port.

So to get accurate number use below calculator to calculate what PSU you need for to support in the enviroment.
