I have a WS-6-Mini giving me multiple alerts that the 24v board's power is out of range:

This unit is at the top of a tower and powers 5 UBNT Rocket 5AC Gen2 access points. It receives 48VH POE from a WS-8-150-DC that is running off of a 24v battery bank that is tied to grid power using a Minn Kota charger. Both switches are grounded.

I have already climbed and replaced the WS-6-Mini with a new one (same Mfg. date & board rev F). The current one, with the error messages listed above, is working better in that it is only giving me the out of range error. At the moment everything connected to it seems to be working just fine. The WS-6-Mini that was up there before was both giving these messages as well as regularly dropping the ethernet connections; attached devices would remain powered up but all connectivity would be lost.

I've seen in the forum others that have had "out of range" issue show up. Is there an easy fix that we can do here (we are skilled with a soldering iron) or must they be RMA'd? Also, can we identify which units may have this issue by looking at the serial number, MAC address or Mfg Date?

Thanks;
Mike

P.S. I absolutely love these switches and setting up towers with the DC unit at the bottom and the Mini up top.

Please post a screen grab of the Device/Status TAB of the switch (see my footer for upload instructions)

Was there a resolution to this?
I have almost the identical problem.
I have a WS-6 mini Rev F with firmware 1.4.6 powered by a UBNT 50v AirFiber POE brick that has been working fine with 2 Rocket AC Prism Gen 2 radios.
Last Friday we installed a 3rd Prism Gen 2 radio and started getting problems with the switch dropping ethernet connection but the radios remain powered up.
Obviously all communication is lost until a power cycle.
We have replaced the POE brick and the same problems continue.
It is also showing 24V is out of range (22.8)
How do we check for batch with bad caps?

Is there a list of Mac addresses or date codes that tell us if a WS-6 mini needs to be RMAd or not for the bad cap issue.
I know they can be tested on the bench but that is not practical when they are all on top of towers.
I don't want to have to pull them all down just to test them and I do not want the problem I have now with the lockups and requiring a power cycle.
I have searched the forums and only find the way to bench test them.

same Problem..is there a solution?

The solution sadly is to RMA the unit if you encounter a WS-8-150-AC or WS-6-MINI that reports 24V out of range and or reboots.

If you want to bench test unit you suspect to have the bad CAPs is to power it up on the bench.

Link up all ports at 100M, preferably 1G, a POE device is not required just a link.

MAKE SURE NOT TO CREATE A LOOP

If the unit starts acting up within an hour or so (reboots and possibly locks up) you know you have a defective unit.

This only affected units made well over a year ago but we will warranty this issue as long as you have the switch and it is undamaged and works properly otherwise.

Hey Chris,

I've a switch in the field that's been complaining about the same thing. Here's the log since the last time it was cleared. A few times a day, and we only lose a few seconds - no intervention needed.

Code: Select all

Apr 27 11:32:49 switch[988]: 24V is out of range (22.7V)

Do you think this is likely to be the same problem? Or is it more likely something dodgy draining the power?

We have 5 ports in use, 3 doing PoE.
Port 2- 48VH,
Port 3- 48V,
Port 4- 24V

Port 3 seems to be drawing intermittently ~0 and 20W, which would bring total consumption up to ~45W. Total Power Usage chart confirms this, normally stable at around 20W with spikes up to just over 40W

Looks like it was damaged, most commonly from Ground current.

Here are some good posts on grounding:

Read the posts above but the basics are as follow:
Tower ground rods must be bonded to electrical service ground rods HEAVY #2 wire.
I always add 1 or 2 “new” ground rods to older existing electrical services.
You will need to RMA it but you need to fix your grounding or you will suffer this damage again. Now it is possible a sensor failed but this is not common and can not tell until we look at it.

The tower ground MUST be bonded to the electrical service ground rods with a heavy direct wire else your Ethernet Cable becomes the bond. Then during rain events or an excessive amount of current sent to ground on the electrical service might see the tower grounds as better path to ground and travel through the switch to the radio to the tower to the tower ground rods.

I have the same problem - 22v is out of range. However, the unit does not reboot or lock up. The only problem seems to be the error log itself ..

Do I need to replace these switches?

Thanks
