Platform Considerations
You can install JUNOSe software 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 router.
■ See the E120 and E320 Module Guide for modules supported on the E120 and
E320 routers.
Installing Software When a Firewall Exists
When a firewall separates the router from the network host, you must use FTP to
transfer the software release files from the network host to the router. In this case,
you must configure the FTP server on the router and ensure that FTP client software
is installed on the network host.
For this network configuration, you must install the software from the normal
operational mode of the command-line interface (CLI). You can access the CLI through
either the local console or a Telnet session. If you have not yet configured the router
to support Telnet, then you must use the local console.
To install the software, perform the following tasks. (See Table 12 on page 127.)
