WS-12-250DC lockup

OK no worries. Any plans to put 24v load bar graph in status page if possible? That would be super handy.

Is there a limitation in the WS-26-400IDC on 24v?

The WS-26 boards have 160 watts of 24V for ports 1-12 and another 160 watts of 24V for ports 13-24 as that board has two 24V power supplies.

Hi again,

Just trying to determine the manufacture date remotely, is this possible some how?

Is there a way to tell if this is fixed by

Board Rev F
Power Supply Firmware Version 53
Power Supply Board Rev B

Thanks!

Why not update the firmware see if your problem still exists.

If still persists disable Flow Control.

And by the way none of our switches ever locked up.

As i said this problem still existed after the firmware update - it only resolved once we reduced the 24v load.

I am trying to figure this out on other switches we have as we are adding more load on them and i need to know if they are at risk of load issues now and not once they have been loaded - we have a lot of switches that may be this age i just need a way to identify them better thats all.

Thanks!

Board Rev F
Power Supply Firmware Version 53
Power Supply Board Rev B

The reason I suggested upgrading was in red above as that should be Version 70 if your on v1.5.0.

In the post I linked on the 24V power supply increase it says

In older WS-12-250-AC / WS-12-250-DC / WS-12-400-AC / WS-12-DC made in early 2017 and prior the 24V power supply on the board was only rated at about 108+/- watts.

About 18 months ago we modified the design for all new boards being made to increase the rating to about 160+/- watts to better handle newer radio power requirements.

I know this is not that accurate of a way to determine and for that I am sorry. We should have made a board Rev change in the software which I had suggested but since our programmer did not agree with me since the 24V MOD required nothing to change in the software. In fact I personally had wanted the 24V power supply to be rated higher from the beginning but the internal thought was newer radios would use less power not more......I ended up being right, and as soon as we saw the newer radios demanded more power we did then make the change to 160 watts.

Now our WS-24 and WS-26 and the OLD EOL WS-12-250A and WS-12-250B did always have 160 watt 24V power supplies.

Keeping in mind the WS-24 and WS-26 have TWO 24V power supplies 1 for each bank of 12 ports each 160 watts.

Another thing users can do is always power AFX radios with 48V not 24V. I constantly see people powering AFX radios with 24V or 24VH

If your not sure a WS-12 unit is older than 18 month and you have a suspicion it may be older as radios are rebooting (it does not lock up) then simply move a couple 24V radios temporarily to POE bricks and turn the POE off for those 2 ports and if the issue stops you then know you have an older unit that needs the 24V MOD to resolve the issue.

Ok no worries. Yep thats sort of what i was getting at e.g a revision number for the change etc. If we provide a serial would you be able to tell?
