Booting the System
This chapter provides information about booting your E Series router.
NOTE: The type of file you must always use for booting your system is a software
release file with the extension .rel.
This chapter contains the following sections:
â– Platform Considerations on page 509
â– Configuring Your System for Booting on page 509
â– Rebooting Your System on page 514
â– Operations in Boot Mode on page 517
â– Displaying Boot Information on page 517
Platform Considerations
System booting is supported on all E Series routers.
For information about the modules supported on E Series routers:
â– See the ERX Module Guide for modules supported on ERX7xx models, ERX14xx
models, and the ERX310 Broadband Services Router.
â– 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:
â– An existing configuration file to be used each time the system reboots
â– An existing configuration file limited to a single reboot
â– An existing script file to be used on only the next reboot
