Cisco 2960 all lights went orange for a few secs

Hi all

I noticed on my new cisco 2960s switches, that all the lights went orange for about 10 seconds then went off again, this was during normal operation, all ports were shutdown at the time apart from a few,the ones that were enabled, the led's went off

what is this some kind of loopback test?

If you've just powered up the switch, then yes.  It's part of the Power On, Self Test (POST).

hi

no the switch had been powered for a few hours.

Possibly STP state change or other temporary inconsistency. You can look at the switch log.
