Note to Users of
Other Network
Access Products There are a number of significant differences between the operation and
functionality of 650 Series products and other Network Access products in the 65xx
and Vanguard lines. These differences include the following:
• Operating software is divided into two distinct segments: base software and
option images. This is discussed in detail in Chapter 3, Installing and Cold-
loading 650 Series Software.
• TFTP functionality is partially enabled by Software Access Key (SAK). The
SAK’d portion is the ability to perform a base software download via remote
TFTP server.
• Flash-to-flash transfer is not operational on a 650 Series products.
