Upgrading Software from an NVS Card

Copyright © 2010, Juniper Networks, Inc.
Your software upgrades may be available remotely through Telnet or FTP, or may be
delivered on a new NVS card. Depending on how you access the software updates, there
are two different procedures to follow. See the appropriate section for instructions:
"Upgrading Software Remotely Through Telnet or FTP" on page 133
"Upgrading Software from an NVS Card" on page 133

Release 5.1.1 or lower-numbered releases only support application images up to 172 MB.
To install larger application images for Release 6.0.0 and higher-numbered releases,
you must first install Release 5.1.2 (or the highest-numbered 5.x.x release). This enables
the system to support application images greater than 172 MB. For example, you cannot
go from Release 5.1.1 to Release 7.2.0 without first upgrading to Release 5.1.2 when you
upgrade the software from an NVS card. See Table 15 on page 133.
