I have a Cisco 4507R (Supervisor IV) that I need to upgrade the IOS on, and have decided to upgrade to 15.0.2-SG7 (ipbasek9). The current rom that is installed on the switch is 12.1(12r)EW; do I need to upgrade this in order to use 15.0.2-SG7? I believe I seen that ROMMON 12.2(31r)SG is recommended but I am not sure if this is required.
If it is required, is there a way to upgrade the ROMMON without bringing hte switch down? I know I can update the IOS without bringing the switch down, but am unsure about this. I will be upgrading this switch via telnet. Any help is appreciated.
Your best bet would be reading the release noties for the targeted IOS. Sometimes, you may need to upgrade ROMMON on line cards as well. Any rommon update needs the module reset (not switch) to take effect.
