Download Information

There are two software images for all Catalyst 3550-24 and 3550-48 products—the Standard Multilayer Software Image (SMI) and the Enhanced Multilayer Software Image (EMI). Catalyst 3550 switches that were purchased with the SMI preinstalled (WS-C3550-24-SMI, WS-C3550-48-SMI and WS-C3550-24-DC-SMI) are only authorized to be upgraded to the most recent SMI. If an enhancement to the EMI is desired, a software upgrade kit must be purchased before an authorized EMI software download. The part number for the EMI software upgrade is CD-3550-EMI=. If the Catalyst 3550 was purchased with the EMI preinstalled (WS-C3550-24-EMI and WS-C3550-48-EMI), or CD-3550-EMI= has been purchased for the switch, then the downloading of the most recent EMI is authorized. All Catalyst 3550-12T and 3550-12G switches have been shipped with the EMI and are authorized to be upgraded to the most recent EMI. Downloads of the SMI and EMI files will be monitored for adherence to this authorization.

Customers can download Cisco IOS Release 12.1(9)EA1 software from Cisco Connection Online (CCO) in the Software Image Library.
