Cisco IOS file names look complex, but they follow a strict nomenclature that reveals exactly what the software contains:
. It is a "tar" archive, which differs from a standard ".bin" image by including both the system software and the web-based Device Manager Cisco Community Key Specifications & Features New Cisco Switch Problem After Upgrade - Page 3 c2960s-universalk9-tar.152-2.e9.tar
A: No. The 2960 (non-S) uses different images, typically c2960-lanbasek9-tar.xxx . Using a 2960S image on a 2960 will brick the device.
