WS-12-400-AC - acting

[kdsnetworks]

Hi All, I could not find any related posts so im writing what i`m experiencing lately.

WS-12-400-AC -
Firmware Version1.4.8rc7 Board RevE

Very randomly - (could be due to heat) drops only AF5x and Prism AC (causing reboot) ... Power is set to 24v (normal)
They all reboot at the same time - making me think this must have something to do with 24v voltage
On that same switch we also have 48VH AF24 which does not reboot and also 3 nano bridges which also do not get rebooted. Just the above.

Switch is at the pick at 230Watt / average is about 145- 180 Watt

Here are my Temps




Board Temp
51C


CPU Temp
76C


PHY Temp
72C



This have been running for more than for 2 years with out any issues .. this year we have this random reboots.

My question is - could the temp contribute to such behavior ?

Another switch in the same enclosure WS-12-250-AC runs just fine and have a little different temps read outs.






Firmware Version
1.4.8rc7


Board Rev
F




Thermal



Board Temp
46C


CPU Temp
60C


PHY Temp
72C



If some one could provide some thoughts - One thing is to lower the temp and see if the problem goes away however it is not practical as it already has good ventilation and adding an AC is not possible.

Could be a defective 24V power circuit, you could rma it

You should be powering AFX radios with 48V or 48VH - READ THIS POST: viewtopic.php?f=6&t=1215#p9040

Thx Chris,

Will RMA this unit ... hope you confirm it is defective as most of time it works just fine and when it acts the only environmental change is the temp.

BTW thx for the af5x 48v tip .. never bother to read more on this.
