Hi,
In a wiring closet this morning one 3750X switch in a stack of three switch was not working. No led at all. I unplug the AC power and remove the stack-power cable. Meanwhile the 2 others switch continue to operate without problem since I have a fiber link on switch 3. Plug back the AC power into the switch 1 and it join the stack and work as usual. Plug back the stack-power after.
What can cause a switch to stop operate suddenly ? It's the second time this problem happen. No message in the log.
If you have a hint where to search, I will be very happy.
IOS : 15.0(2)SE
Thanks.

Did you try moving a power supply? There's a possibility that you have a hardware failure.
You might consider upgrading your IOS. Leo, I believe, would recommend 15.0(2)SE4.
Agree on this. 15.0(2)SE4 is a good IOS to use for the 3560G/E/X and/or 3750G/E/X.

Hi,
Thank for your answer. I will try to update the IOS to15.0(2)SE4 this week. Is it too early to upgrade to 15.0(2)SE5 ?

No, not early. It's too BUGGY to upgrade to 15.0(2)SE5.
