Netonix Forums

We have a new AF5x unit that we just put in as a replacement for an old Rocket link. Had an old Netgear GS-108 switch there, which was replaced with a NEW WS-8-250 unit. The WS is powering the AF5x unit. It will NOT connect up as a 1 gig port to that switch ! Only connects as 100 Mbps port. This seems to be sending tons of errors back up my network! I am going to insert the UBNT "Brick" in line today, and see if that fixes the issue?

On the other end of this link, we have a WS-12-250 switch which powers the AF5x, and it seems to have no problem connecting up as 1 gig !
Although it will NOT power the Mimosa B5c correctly at that location (might be cable problems, replaced the CAT5, and might need CAT6 instead?)

WS-8-250 has 1.2.0 FW in it,
WS-12-250 has 1.1.8 FW in it !

Going to upgrade to the 1.2.2 FW today ?

Flow control is ON on all ports !

The WS-8 does not have 24VH ports like the WS-12. In theory, it _should_ work on non-VH if the run is short.

AF5X can use all 8 wires for PoE. If you only use 4 wires, you double the current on the Ethernet transformer. If you have a bad crimp and only use 2 wires, I think it can quadruple the current.

Hi Wayne,

Since there are tons of people powering AF5X with our switches since the first BETA Super Users got the first PRE-RELEASE AF5X radios with no issues I am going to have to say it is one these 3 possible issues:

1) The cabling or end is bad or if your using an Ethernet Surge Protector it is bad or not rated for 1G?
Did you run a cable diagnostics on the port?
To run the cable diagnostics click on the little gear on the far right of the Port Row on the Status Tab.
You may run the diagnostics on ports that are powered it does not hurt anything.
Also do you have an Ethernet surge protector on this as maybe it is the problem?

2) The port in the switch could be bad, it happens!
Try moving the AF5X to another port. (POWER OFF THE POE FIRST DO NOT PLUG AND UNPLUG LIVE POE)
If the problem moves to the other port I would say you have bad cabling, ends, radio, or surge protector issues.

3) The AF5X is bad.
Try swapping it out but these are in short supply so might be hard to do.
It is just as probable that the Radio is bad as our switch is bad.
Actually we have an EXCELLENT record, 2,000+ switches 14 RMA's and of the 14 RMA's 5 were fixed with firmware upgrades that the user did not do.

Also how long is that cable on the AF5X as the WS-8-250-AC does not offer 24VH and if you are powering an AF5X with a standard 24V port the cable run should not exceed 150 feet. Also make sure it is in a port that offers 48VH as an option as those ports have higher rated Poly Fuses. With the newest firmware it tells you the port current rating when you select the POE option for the port. The only switch models that we currently offer that support 24VH if the WS-6-MINI (PORT 2) and WS-12-250-AC (PORTS 1-4).

As far as Mimosa there are also a lot of people powering their devices with our switch with excellent results (Including me at my WISP). Mimosa recommends putting their radios in a 48VH port, I have run it both ways using standard 48V but was in a 48VH port so it had .75A Poly Fuse as older Revs of our board only have .5A Poly Fuses on non VH capable ports. Once again with the newest firmware it tells you the port current rating when you select the POE option for the port.


There are over 2,000 of the WISP Switches in service around the world powering every device Ubiquiti and Mimosa makes with no issues so I do not understand why when people run into a problem they always first assume there is something wrong with the switch design or firmware. Almost every time it ends up being a bad cable, cable end or Ethernet surge protector (I HATE ETHERNET SURGE PROTECTORS). Now it is very possible there is a bad port but I highly doubt there is 1 bad port on the one switch feeding the AF5X and just coincidently there is another bad port on another switch connected to the MIMOSA link? I mean it could happen but the odds are extremely high.

I would of course recommend upgrading the firmware to v1.2.2 but v1.1.8 and up are rock solid but if you did not reboot the unit a second time when upgrading from a version older than v1.1.8 that could cause weird issues which is why we instructed people to reboot the switch a second time after upgrading to v1.1.8 or above from an older firmware.

Below are screen grabs I "just" did - Note time on windows screen.

Now you might say my switch is a WS-24-400A and yours is a WS-8-250-AC but they are the same switch core, same parts, and same firmware just a different size.

Turns out the port on the AF5x was bad! Brand new out of box ! Replaced the radio and got 1 gig connection on new radio with the WS-8 powering it.

Chris, I will be sending you a PM regarding a problem with a WS-12-250a unit !


Thanks,
Wayne
