do a show version on your box. You will see the filename which is something like s72033-ipservicesk9_wan-mz.122-18.SXF13.bin

If it has the "k9" in it, then you can use SSH because it supports encryption, if it doesn't have it, then it is not supported and you should perform a software upgrade to support it.

Pls rate if this was useful for you.
