(e.g., WS-C3560E-24TD-S, WS-C3560E-48PD-S).
Note: The /reload flag automatically reboots the switch after a successful upgrade. Alternative: Binary Upgrade Method If you must use the BIN file: copy tftp: flash:c3560e-universalk9-mz.152-4.E10.bin boot system flash:c3560e-universalk9-mz.152-4.E10.bin write memory reload 5.

Instruct the environmental variables to point to the new image upon the next device reboot:
: The "universalk9" designation includes all feature sets (IP Base, IP Services), which are unlocked via software licenses rather than separate image installs.

: This indicates a universal software image containing all feature sets (IP Base, LAN Base, and full Layer 3 IP Services) locked behind software license activation keys. The k9 designation guarantees strong cryptographic payload support, enabling secure management features like SSH, 3DES, and AES.
Depending on the activated license, this image unlocks advanced routing protocols:
Upgrading to 15.2(4)E10 is recommended for organizations still operating older 15.x or 12.2SE releases on their 3560X/3560E infrastructure. Note: The /reload flag automatically reboots the switch
The 15.2(4)E release has documented limitations. Review the official release notes (Cisco.com login required) for a complete list:

: This refers to the image type. "m" indicates the image runs from RAM (not compressed and executed in place), while "z" signals the image is compressed (zipped). The combination suggests an image that is compressed for storage on flash but is designed to be decompressed and run from RAM for optimal performance.
