5320-16p poe budge quest

[Terry_Yang]

Hi Sirs

I check the 5320 datasheet

the 5320-16p poe power budge is only 185w , so if every device which connect 5320 need 15.4w power budge  , does the 5320-16p only use 12port  POE ?

185w/15.4w=12.01...

Hi Sirs

Thanks for reply 

At least I know the poe port limit of 5320-16p. Regarding the planning of 5320-16P, what should be paid attention to

It is quite common that switches have a total PoE budget that is less than what a single port can use multiplied with the number of ports. It is also quite rare that a switch has more than a few ports that use a lot of PoE power (regardless of vendor). For more power you need to look at other models, like the 5420F-16MW.

It's being sold as a 30W POE switch and bears no specific mention that it's only going to power 6 ports apart from a separate section listing the power budget on the switch. There is no specific mention around maximum port availability.

You and I might check the power budget, but not everyone would. Assumptions would be made based on the sales literature.

The max PoE power budget is mentioned in big letters on page 4 of the datasheet, which in my opinion should be the primary technical sales literature for any device (no matter if switch or other technical device).

Also the amount of ports that can utilize PoE fully depends on how much the specific PDs are actually drawing, which may also only be 7W on a specific port. In that case it would leave more over for other PD's/ports again, so "amount of ports" can't be generally predicted, hence the "maximum power budget".
