Where can I find the datasheet ?

I have clicked on product page button where is written download PDF, but inside I can't find any detailed information about it.

Is there some link here on forum ?

That PDF is out of date.

The WS-26-DC requires the same conditioned 48v input power as our WS-12-DC. There are 2 SFP ports, and 24 10/100/1000 copper ports, all of which provide passive POE.

6 ports provide 48VH power (1-6)
2 ports provide 24VH power (1-2)
All ports provide 24V and 48V power.

Sorry about that. Is there a specific question I might be able to answer about them?

Thank you for your attention.

I need also to know what is total max power consumption so I can decide what power supply to use

Well the switch itself uses up to 12+/- watts depending on how many ports are linked and how fast the fans are running then you need to add up all your POE devices you plan to power.

Then over size your power supply and account for inrush demands.

Well one would think you would add up all the POE devices you are going to power then add 16 watts for the switch itself?

If you want a useless theoretical number then simply add up the max POE option per port.

Assuming a 48V power supply
Ports 1-6 48VH @ 1.5A = 75 watts each port x 6 ports = 450 watts
Ports 7-24 48V @ .75A = 36 watts each port x 18 ports = 648 watts
16 watts for switch itself

So 450W + 648W + 16W = 1114 watts but I doubt you would deliver that much POE

Maybe think more reasonably about what you're powering on each port then add that up and add 16 watts

Keep in mind the WS-26-DC is NOT to be used with negative 48V, in this case you use the WS-26-400-IDC which is designed to use with negative 48V sites like telecom sites.

Hi,

Is there any datasheet ready for the WS-26DC and WS-26-500-DC models?

Thanks
