All had voltage fluctuations and stopped forwarding traffic/flapping ports at some point. Upgraded to 1.4.5rc2, this helped but did not fix the issue. Had to remove and put in tough switches. 12 port netonix in the same environment are working fine. Is there another fix planned for this going forward?
We did have some (less than 1%) WS-6-MINI and WS-8-150-XX units that went out with defective CAPs but the estimated # of units affected by this is less than 1% of that production batch so it seems very odd that you would have EIGHT of them but I suppose it is possible if you have terrible luck?
Anyway simply RMA them and we replace the defective CAPs and will send them back to you ASAP.
Please follow the RMA instructions located here:
viewtopic.php?f=6&t=1259All WS-6 and WS-8 switches with a Manufactured date of 9/7/2016 or newer have had the CAPs replaced, any unit older than that have had a 1% or less chance that their CAPs are defective.
But the symptoms of the unit having defective CAPs is that the voltages (3.3/24/48) on the device status Tab will fluctuate with anywhere from 4 or more Ethernet links active and on an even rarer instance this voltage 3.3V fluctuation can be just enough that the unit will reboot. The 24V and 48V are not really fluctuating but since those readings use the 3.3V reading as a baseline they also falsely report an exaggerated fluctuation.
The reason we missed this during testing is we do test each port one by one to achieve a 1G connection before we serialize the unit but not all ports are active at the same time and for this to show up 4 or more ports need to be active.
But there should be no way that the voltage fluctuation would cause traffic not to pass other than the unit is rebooting.
