Hi,

Normally when you insert second sup as a standby (same type, hardware
configuration including PFC and memory) it should synchronize itself to
active one including IOS and configuration (except configuration
registers) and reload as standby. But I normally recommend my customers
to manually load proper IOS to supervisor on spare chassis and insert
prepared one into production chassis.
