Airfiber 24 drawing high current off ws-24-400b
I have two airfiber24 radios, one in eth1 and one in eth2 (both configured for 48VH) on a ws-24-400b. According to the netonix GUI the AF24 that is plugged into Ether1 is drawing ~55 watts but the AF24 in ether2 is drawing ~82 watts. Could this be a cable issue? The link is up but obviously I don't want to leave it like this because it seems that it is exceeding the rated output power of the netonix interface.

What firmware version? Upgrade if not v1.3.9 and reboot just for giggles.
55 watts is not far off but 80+ watts - WOW
Yea that seems wrong, real wrong.
Possible causes:
Bad current sensors -possible
Damaged current sensors - possible
Damaged radio pulling to much power. - Doubtful
82 watts is exceeding the port rating so if it is correct failure is very probable.
I would investigate.
You could swap the ports and see if the ratings follow.

Firmware is 1.3.9.
I will eliminate the port being a problem by switching to another interface. It appears that only ether1 and ether2 have 48VH correct?

Yes the 400B only offers 48VH on ports 1 and 2
Do not try and power AF24 on normal 48V ports

ok so with nothing even plugged into ether2 on the netonix switch it still shows a wattage draw of 40~ watts. What do you think?

Sounds like the current sensors are damaged?
This occurs from the components being exposed to voltage > 60V which would be from ESD or ground potential shift.
Read the grounding posts on good grounding practices.

I guess it is possible but we do check the current sensors before we serialize them?
If they were damaged it is easy to spot as they look like picture 4 and or 5 of this post, they are what most blow current sensors look like which does not just happen on its own.

Either way read this post on how to RMA it and it also shows you how we test each switch before we assign the MAC address.
