: The binary executable format used for booting the switch. Supported Hardware

The Catalyst 4500-E is a modular chassis (available in 3-slot, 6-slot, 7-slot, and 10-slot variants). However, the software image runs directly on the central processing unit housed within the Supervisor Engine. The cat4500e universal image is engineered to support specific generations of Cisco Catalyst 4500-E Supervisor Engines: Supported Supervisors : The binary executable format used for booting the switch

Check your bootflash capacity using dir bootflash: or dir slavebootflash: (if running dual supervisors). The binary size hovers around 180MB–230MB depending on the specific build, requiring sufficient unallocated flash space.
