USB stick installation works fine, but as edondurgunti says, if the SNS is installed at a remote location, it's a worst case option and not practicable.
Same here, fresh install of SNS3655-K9 with ISE 3.0 ISO. (Keyboard/Mouse Mode)Stuck at the second time by the installation through CIMC at 562/596 CARSisePKg1. Next I try through USB stick installation.
