Cisco CAT4500E IP Base IOS Upgrade Without Crypto

Move an installed Cisco CAT4500E platform to the IP Base Cisco IOS software edition with an upgrade explicitly supplied without cryptographic functionality. S45EIPBU-15201E= associates the upgrade with Cisco IOS Release 15.2(1)E and the CAT4500E platform, keeping the software selection aligned with the intended switch family rather than a general-purpose IOS image. IP Base identifies the Cisco IOS edition provided by this upgrade. The product is software-focused rather than a switch, interface module, or chassis component, and it is intended for an existing compatible CAT4500E environment. Its upgrade classification makes the current software edition and platform eligibility important technical checks before selection. The no-crypto designation is the defining distinction of this variant. It excludes cryptographic functionality from the ordered Cisco IOS software package, which matters where the required platform software policy does not call for crypto-enabled capabilities. The Release 15.2(1)E designation also identifies the intended IOS release level, helping administrators align the upgrade with their established CAT4500E software standard.
