Management stopped working on WS-6-MINI

[JOFO]

Hi, one of MINIs had stopped responding on management IP. Nothing changed just suddenly stopped responding this morning. Everything is working (PoE, all vlans passing data) just management isn't responding. Is there any way to revive management (e.g. mac-telnet or something else) or powercycle is only way? Thanks.

Are you saying you can not PING it or web browser is not connecting?

[JOFO]

Yes, everything's working. Also another devices on management vlan behind the switch. Only device itself isn't responding to ping, ssh or web. It's like switch has lost its ip.

Then your only option is to reboot it

I was afraid that only option is to interrupt network traffic for few minutes.

So switch had cut off one port and thus connected device was unreachable. So I managed to get it and powercycled switch. After powercycle switch is completely unresponsive. No Link is established on any port and only power led is lit. Reset doesn't work either. What could be the cause? Could you get me some hint which component could be issue? Switch is out of waranty but I'm electrician so repair shouldn't be problem for me. :) I've inspected board by eye but doesn't seem to have any sign of burn component or so.

Sorry, could me many different things.

I wish I could be more helpful.

Has WS-6-MINI serial console pins somewhere on board? I could check if there's any output on power up.

Never mind.. I'll use it for spare parts. Just recovered another switch with blown transformer on 1st port. ;-)
