Cisco PoE switch for WAP321

[rbobek]

Could someone please point me to a Cisco small business switch that would be capable of powering five WAP321's?

I don't know the power profile on these APs but have noticed that the PoE injectors pump out 16.8 MAX watts. I can't find anywhere what the power profile is on WAP321 APs but ~17 WATTS seems to me to be quite high.

In fact, I was interested in the SF100D-16P which has a power budget of 64W over 8 ports... the price range is in my budget.

Could anybody tell my if the SF100D-16P can power 5-6 WAP321's sufficiently? Thank you.

Hello Rob, the answer is yes, the SG100D-16P will sufficiently handle 5 AP.

Thanks Thomas. Do you know the power profile on the WAP321's by any chance?

The WAP support 802.3 AF. Although I don't know specific detail for the power profile I can assure it should not exceed 15.4 WATT. Typically the small business power draw is less than 8 watt per port. Devices which support CDP will also have a min/max draw that optimizes the POE functions.

However, the datasheet and admin guide does not make mention of any CDP

Thanks Thomas for your assistance!

Rob,

We have 6 x WAP321 running off our ESW-520-8 Port Cisco switch - each uses 4 Watts and this switch give s a total of 60 Watts.

So we are only using 24 Watts out of 60Watts available for our 6 WAP321s.

Kindest regards,
