While the image file name starts with cat4500e , it is also widely used on the Catalyst 4500-X Series switches, a fixed-configuration, 1-RU (rack unit) switch known for its high port density. The official release notes for Cisco IOS XE 3.11.xE are explicitly for the Catalyst 4500-X Series Switch. This demonstrates the software unification across the Catalyst 4500 family, where a single image type ( cat4500e-universalk9 ) could support both the modular 4500-E chassis and the fixed 4500-X platform.
