Platform Considerations
System booting is supported on all E Series routers.
For information about the modules supported on E Series routers:
•
See the ERX Module Guide for modules supported on ERX7xx models, ERX14xx models,
and the ERX310 Broadband Services Router.
• See the E120 and E320 Module Guide for modules supported on the E120 and E320
Broadband Services Routers.
Configuring Your System for Booting
Juniper Networks delivers your E Series router already set up with a factory default
configuration and a software release (.rel) file. You can, however, create a new
configuration file (.cnf) and select a different software release file to use in future reboots
of your router. When you reboot your router, you can use:
• An existing configuration file to be used each time the system reboots
•
An existing configuration file limited to a single reboot
