The es8 identifier is specific to the Enterprise Service 8 (ES8) line cards used with Supervisor Engine V or Supervisor Engine V-10GE. Loading this on the wrong ASIC will result in a "Invalid image" or "Hardware not supported" error during boot.

This file contains every feature the hardware supports, but those features are locked behind right-to-use (RTU) licenses. cat4500es8-universalk9.spa.03.11.05.e.152-7.e5.bin
