WS-3550-48-SMI upgrade

I am planning on upgarding some old code on 4 WS-3550-48-SMI switches.

I was planning on using:

Release 12.2.44-SE6

Filename c3550-ipbasek9-tar.122-44.SE6.tar (16 MB Flash reqiured)

It appears the flash only has 15.25 MB of RAM which can't be right??

Directory of flash:/

3 -rwx 342 Jan 01 1970 00:01:26 system_env_vars

5 -rwx 3911 Dec 17 1994 18:14:43 config.text

9 drwx 192 Mar 01 1993 00:03:24 c3550-i9q3l2-mz.121-9.EA1c

15998976 bytes total (11633152 bytes free)

Re: WS-3550-48-SMI upgrade

Flash Memory

All 3550s have 16 MB of internal Flash memory. The Flash memory is not upgradeable.

There is a limit to the number of images that you can store in Flash. Always check the size, in bytes, of the image in the LAN Switches section of Downloads - Switches ( registered customers only) before you upgrade software. Issue the dir flash: command in order to compare the size of this image with the free space in Flash.
