Moving Line Modules Between Releases
The Juniper Networks ERX1440 Broadband Services Router employs a 40-Gbps SRP
module and a new midplane. Release 3.3.2 was the first software release to support
the 40-Gbps SRP module and midplane. Before you can transfer a compatible line
module from a Juniper Networks ERX705, ERX710, or ERX1410 Broadband Services
Router to an ERX1440 router, you must first load Release 3.3.2 or a higher release onto
the current router, and then reboot the router to load the release onto the line modules.
If you then move any of those line modules to an ERX1440 router, that router is able to
recognize the line module.
If you move a compatible line module from an ERX1440 router to an ERX705, ERX710,
or ERX1410 router, the module loads properly in the new router regardless of the
release.
