TL SG2452 no sys light and no access to management page
Hi everyone !
I've a problem with my managed switch (TL-SG2452)
While running, the power led is green and the fans are turning.
But the sys led is always off as well as all the activity led (on every port I plug another device the activity leds are always off)
If I plug another switch the activity led of the other is blincking but not on mine.
If I connect a computer, I don't have an ip address assigned even if a dhcp server is connected to the switch.
And if I put a fixed address on my computer I can't access to the management page of the switch.
I already tried to do a factory reset (unplug power, wait a bit, push the reset button while pluging back the power, continue to hold the reset button for 15 secs then release.
While doing this factory reset the sys or activity leds are always off and the power led is on.
I opened the switch and measured the power supply, it seems to be good.
Have you an idea of what could be the problem ?
Thanks a lot and sorry for my bad english
