CRS328-24P-4S-RM + Audience POE Warning

Hardware MikroTik hardware general
1

Loaded RouterOS7.1 on my Audience for the WiFi Wave2 Driver.

This the BEST PERFORMANCE I HAVE EVER GOTTEN OUT OF A MIKROTIK RADIO.

However…
I am running the Audience as a WAP only. I have set up the 3 radios manually and am “Testing it out”

The Wireless in the house suddenly stopped and I looked over at the Audience to see it booting up.

Checking the Audience Log starts at Power outage.

[admin@MikroTik] > log print
 dec/11 17:13:59 system,error,critical router rebooted without proper shutdown, probably power outage
 dec/11 17:14:03 bridge,info "bridge" mac address changed to 74:4D:28:F7:1B:93
 dec/11 17:14:05 wireless,info 34:F1:50:02:73:EC@HomeWiFi connected, signal strength -56
 dec/11 17:14:05 interface,info ether1 link up (speed 1G, full duplex)

Moving to the switch I see this.

12:08:57 poe-out,warning ether1 detected poe-out status: overload 
12:08:57 interface,info ether1 link down 
12:08:59 poe-out,info ether1 detected poe-out status: on 
12:09:07 interface,info ether1 link up (speed 1G, full duplex) 
12:09:29 interface,info ether1 link down 
12:09:34 interface,info ether1 link up (speed 1G, full duplex) 
12:15:33 system,info,account user admin logged in via local

So which unit crapped out?

Did the Switch Choke on the power demands?
Or Did the Audience Cause the Problem?

I got almost 20% more thruput after updating to 7.1+ Wave2 =)

How do you Power your Audiance ?
You need a 802.3at Type 2 PoE (PoE+)

I power my Audiance via a CRS328-24P-4S
I did some Quick Power test (CAT-6a Cable ~20m 51V)
Laptop and phone during Low-Traffic ~ 6W of Power is needed,
Laptop and phone with medium Traffic up to 14.3 W
average ~ 12 W

If you look at the log entry from the CRS328… You can see that the Audience is powered by Port 1 of the switch.

4

ah you mean CRS328-24P-4S+RM ?

I dind`t find the CRS328-24G-4S-RM…
I thought is was an older Model
with 24G (24 gigabit non PoE )

5

Did you already try with a different / shorter Cable?

6

I didn’t try with a shorter cable.

That cable has been in place for several years and powered all sorts of Wireless Access Points in that time.

Due to the inability to get our GoTo Switches… I used the Mikrotik switch I got years ago. I never used it as it used to shut down a bunch of ports every few days. It has not done that with the current firmware.

The Audience had potential as a cap but the default drivers didn’t make for good connections. The WAV2 drivers WORK MUCH BETTER. But I can’t do caps-man with it.

Good Morning,

  1. PoE-Overload
    I did some Test yesterday…
    I wasn`t able to reproduce the PoE-Overload on any
    of my Mikrotik PoE-Output devices.

The Mikrotik website states a Max power consumption of 21Watts (30W for LTE version)
During my quick tests , i wasn*t able to exceed 14.5 Watts.

I would try isolating the Problem and Power the device directly or via a PoE-Injector.
Just to see if the Device keeps Rebooting unexpectedly.


2. Wave2
I use a Audiance as my Wireless-Access point at Home.
The Wave2 Update did make a differents in performance

But i dont think the "Product" is mature enough ... I wouldnt recommend using it in any type of production environment.

The problem has not reoccurred yet.

The audience with WAVE2 drivers is actually keeping up with some of my dedicated ACv2 WAPs now.

This is all 3 radios running with 5 total SSIDs and a few VLANs. Plus 22 connected clients during the test.

It decided to give me the same problem I see in Tik radios… certain clients start getting their packets dropped.
Other clients get disconnected and can’t rejoin until the radio is disabled and re-enabled.

After 3 devices stayed off line for 5 hours… had to turn my Ruckus AP back on.

It costs more… but everything is working and nothing drops out.

10

Update…

I updated the Audience to 7.1.1

First off.
The unit has not rebooted or shut down, since the install of 7.1.1

And more importantly.
Those 2.4 devices that always drop off after a few hours or days…

HAVE STAYED CONNECTED!!!

No disconnect warning from my system monitor.

Will look over the log to see what it shows there… But I can’t stress this enough. This is the first time EVER that Mikrotik wifi has not dropped those clients.

11

Thanks for the Feedback!

I also updated to the RouterOS 7.1.1
wifiwave2 ist quite stable and performance is awsome

12

The Audience Shut Down again today with the same warning.

I made support files and sent them off to Mikrotik.

13

Support believes the the Audience exceeded the power spec for AT.

Now using the provided power adapter.

Support also recommended setting the port to Low Power which would allow for more watts at 24 V.

14

Thank you for the Feedback!

I have been keeping an eye on my Audiance..
In normal use i don`t exceed 17 Watts of power.
Maybe you have more Clients, longer Cables or a more demanding Config/Setup

Mikrotik say the Audiance can need up to 27 Watts :frowning:
Even the CRS328-24P-4S+RM can`t provide that kind of Power.

15

Yup..
27 vs 25.5

Thats what kicked the voltage overload, and shut down from the switch.

I have another WiFi running the house at the moment… so i can’t test that low power setting right now.

@smyers119, That strange the Mikrotik Website, says something else

I don`t know if i can edit the Voltage, but my CRS328 provides 26V & 52V
That would mean,
High-Voltage = 52 V * 450 mA = 23.4 Watts
Low-Voltage = 26 V * 1000 mA = 26 Watts
