Hello Experts,
I recently formatted the flash drive of an 1800 router and replaced it with an updated image. However, the new features within the new image aren't reflected in the router. I believe that this is because a reboot would be required for the updates in the new image to be reflected in the router i.e. the image needs to be added to the system.
Can someone tell me to get the image to the system without a reboot and if by doing so I would get all the new features from the image.
For example, the show version below shows the old image in the system as
flash:c181x-advipservicesk9-mz.124-6.T7.bin
Whereas the new image is on the flash as
c181x-advipservicesk9-mz.124-24.T2.bin
I was thinking of doing a:
copy tftp flash:c181x-advipservicesk9-mz.124-24.T2.bin system:c181x-advipservicesk9-mz.124-24.T2.bin
If I do the above will I get the features with out showing a reboot?

Hello Carlton,
a reboot is needed to have the router to load the new image that you have placed in the flash.
There is no other way to do this.
The IOS image file is actually compressed and it is expanded in RAM at boot time.
Schedule a maintenance window for the reload.
>> copy tftp flash:c181x-advipservicesk9-mz.124-24.T2.bin system:c181x-advipservicesk9-mz.124-24.T2.bin
stay away from this kind of attempts.
Hope to help
