-	Type "dir image" to get a listing of the image files on the system
-	The file system can only store a maximum of two :"img" files, if the file 
	system on the switch contains two ".img" files you must delete at least one 
	before proceeding.  To delete a file type the following command 
	"delete image:image-name.img"  You will be asked to confirm file deletion.
-	Copy the new image on the switch.  
	Type "copy ftp://userid:password@ipaddress/TopspinIBMBC-TopspinOS-2.2.0-build555.img image:TopspinIBMBC-TopspinOS-2.2.0-build555.img".

-	FROM THE MANAGEMENT MODULE WEB INTERFACE, restart the switch.  WAIT for the 
	switch to return a "Post complete" message on the I/O module status table.  
	This may take 8 to 10 MINUTES.  Do not interrupt the switch while it is posting.
