"1)I have uploaded the software as a secondary image on a switch,i want to reload the switch to boot with secondary image if suppose it fails to boot"
execute a 'boot system flash secondary', if it fails, the switch will reboot back to primary.
"3)I m trying to boot by K_14_49m.swi and after sucessful upgrade to K_14_49m.swi i will try to boot by K_15_02_0005.swi is it compatible with the below ROM version."
read the release notes for k.15, page 16, it says which ROM ver you need to be at.
"4)What is the command to see enough memmory for these images??"
Not an issue, memory is fixed and there is enough.
