What the real power using on MS210 switch ?

Hi All,

I have a question about the power consumption of MS210. According to the datasheet (attached image), MS210 has 2 power items: Power Consumption and Power Load (idle/max). Which item is the actual power consumption, I think it is Power Load (idle/max)?

I  believe power consumption is the actual power being used and power load is the feature where you can reduce the power consumption by turning off unused ports at scheduled times. For example, I turn off ports connected to access points in buildings closed on the weekends.

It is best to look at the idle/max of the MS210-24 or 48 to see the actual min/max values of the switch itself without any PoE added to it.  So that would equate to a max of 24W on a 24 port version and 42W on a 48 port switch.

The other switches then add more power overhead due to the use of PoE on the ports.  And seeing you can have up to 370W of PoE+ power on the 24P and the 48LP but the total is wattage is higher than the 370W + 24 or 42W meaning you still have some extra overhead from the PoE distribution.

So each switch has some basic operation wattage for it's CPU, CAM/TCAM, RAM, and then some power to maintain each port's ethernet connection to the endhost.  That's why the 48 port has a higher max power without PoE figures.  So it all depends how many devices are plugged in.

Thanks, I know this. But have spec 15-882W on all model it not possible. I think Power Consumption in specs it maximum power chassis on model MS210 can reach. The real power is Power Load.

Thanks for answering.
