Cisco switches 3560 need manual reboot after power outages

Hi everyone,

In africa we have lot of power outages.

Working at a very big company with more than 300 switches can be challenging if you have to bring them up by manually rebooting few of them on the property.

The switches are directly connect via fiber using LH/LX SFP connector to a 4500 Core switch which is on a UPS and does not go down during the outage; only the access layer switches will then need manual reboot....

Please assist in having a permanent fix on this issue.

Thank you very much in advance.

I'd be upgrading the IOS to something more recent, like 12.2(55)SE8.
