I have done many upgrades on 6500 and 7600 with dual sups.
Last night i did an upgrade for 4507 with Sup II plus.
I upgraded then reloaded the standby first, but when i switch the redundancy to upgraded standby the whole thing went down for about 2 minutes.
Have i done something wrong?
is 4507 with dual sups not capable of doing in-service upgrades?
any help or suggestions much approciated.
