HI, MDS9509, supervisor in slot 5 is hw version 5.2 and in 6 is 4.1 (or 4.0?)version. When switch is rebooted, system led lights orabge on both supervisors, if I look at device manager, the only orange is active at slot 6 (as supposed to be) so device manager show different then real world.
When I do manual system switchover to 6, all leds on 6 become green, then switchover back to 5 and everything is ok (so only one orange, on 6 active).
The same happens at box, where both supervisors are at 4.0 version of hw.
When I downgraded to 1.3.5 image, problem is gone.
