Can you capture the output of "show version" and post it here so that we can see the amount of DRAM and FLASH of your 3550?

However, the latest version for C3550 EMI IOS IMAGE AND WEB BASED DEVICE MANAGER is 12.1.22-EA8a (ED)

The file is c3550-i5q3l2-tar.121-22.EA8a.tar which requires 64MB DRAM and 16MB FLASH to install.
