Ruckus R550 - not enough power

bdillard

Hello,

I have a lot of R550's getting powers from different manufacturer switches but they all seem to have the same warning about not getting enough power. These are running the current firmware -R550_200.12.10.105.129. According to the website they only require 802.3at PoE+ Max power consumption PoE+ : 18.71W. I currently have the AP plugged into a switch with a 240 watt power supply for 8 ports. The specs on it are minimum of 19.39 W per port. I only have 2 ports plugged in on the switch. I have another conneted to a 30watt poe injector. They both have the same indicator -

According to Netgears website the 8 ports are PoE+
802.3at
Ports.

My POE injector is rated at 30w - is there a typo on the website for the R550? Do they a require 60watts?

Hi @bdillard

It seems though the switches are providing POE+(at) the AP might still be negotiating at af mode. Can you hardcode the power mode to AT in your all APs ? Login to the master first and execute below command, if you see it as "auto" and "af" next step would be to hardcode power mode:

ruckus> enable
ruckus# ap-mode
ruckus(ap-mode)# get power-mode
PoE Configured Mode : Auto
Power Consumption Status : 802.3af Switch/Injector

To hard code the power mode :

On Master :

ruckus(ap-mode)# set power-mode at

On slave :
rkscli: set power-mode at

Hi @bdillard

ruckus> enable
ruckus# ap-mode
ruckus(ap-mode)# get power-mode
PoE Configured Mode : Auto
Power Consumption Status : 802.3af Switch/Injector

To hard code the power mode :

On Master :

ruckus(ap-mode)# set power-mode at

On slave :
rkscli: set power-mode at

Thanks - I've got 5 different networks with the same issue - different POE switches. I'm thinking that sensor/auto doesn't work automatically.

Thank you Vineet for the clarification. All clear now!

Hello Vineet,

One of our customer faces the same issue , customer is using POE injector of 802.3at Standard.

do we have any comments here please.!

Hi @manjunatha_nara

Can you share the output of "get power-mode" from this AP ? What is the POE injector type in use and the AP model ?

Best Regards

Hi Vineet,

I have connected to the master using SSH as follows

ssh -oHostKeyAlgorithms=+ssh-rsa admin@192.168.1.200

ran the commands and now have the Master in AT power mode.

But I cannot connect to the slaves AP's via their IP addressees, they just time out...

Is there a different connection method for the slaves?

Any help greatly appreciated.

Hi Vineet,

We have some R550 access point. According to the datasheet its only required power is 18.5W. When i plug that into the Cisco switch and run the power inline command its displaying 28.5W consumption. Actually why is that ?

I think it is like when game specs say only requires 8Gigs of memory and a 8gig video card and you play it and it doesn't look like the demo and that's because they have it playing on 32GB of memory and a 16gig video card with RTX. I think if you want the full wifi6 experience you want 30watts.
