We recently setup our new 4510 chassis and I'm having issues with the redunant supervisors not being redundant.
I'm under the assumption that switching between SUPs during IOS upgrades should be seamless and not drop the network connections?
This is the upgrade link I've been following: http://www.cisco.com/en/US/products/hw/switches/ps663/products_configuration_example09186a00801461ef.shtml#task4
Everything works fine until I force a switch over. At that point the switch drops all connections for approx 30 seconds.
Here are some of the settings on my chassis:

Should I exect this unit to stay up during a switchover? Thanks.
