ws3560 reloading itselfs

[sanjar200994]

Hello, I met strange problem for me. Few days ago WS-C3560CX-12TC-S started rebooting every day (3-4 times). I changed switch to another new WS-C3560CX-12TC-S but I still have same situation. Temperature is normal, power supply to (all devices connected from 1 socket, but just this switch rebooting). Please help ...

Take the same switch, the one rebooting constantly, to a different part of the building.  See if it is still "reloading itself".

[sanjar200994]

do you mean that it could be electrical problems?

[Richard Burts]

If 2 different switches have the same problem when connected there it certainly could be some issue with power there. I think the suggestion to try the original switch is a different location is a good idea.

Is it possible to have something connected to the console and displaying console messages? It might be helpful to know if there were any console messages at the time that the switch reloaded.

Exactly.

[marce1000]

           - Issue the show version command and have a look at the reload reason , 

 M.

[MHM Cisco World]

Do you use any EEM or script to reboot the SW?

Check time between reboot if interval is same then there is something in your config it not HW issue.

[sanjar200994]

there are no scripts and something than can reload this switch. In config I just use different vlans on different ports. HW issue could be, but I have 20 other same switches and they work normally

[MHM Cisco World]

As @Leo Laohoo  mention check power supply inlet. Also check cpu history always.

[Richard Pidcock]

You could try upgrading the code to a different version I suppose, but looking at the "show version" output provided above shows the following which might lead me to believe it's a power issue as suggested by others.  If you could move it to another power source that would be a good validation step.

[sanjar200994]

thank you everyone, really it was problem with electricity, I didn't know that in this office 2 different electro lines. But it still strange that just 3560 reloaded, other equipment worked (router and others). it seems that 3560 is more sensitive to electricity  

[Richard Burts]

Thanks for the update. Glad to know that you have identified the issue as an electrical problem.
