Command Reference Guide
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.
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 119.)

Table 12: Software Installation Procedure When a Firewall Exists

1. Obtain the required information for the installation.
2. For routers that are currently operating, divert network traffic to another
router.
3. Access the Privileged Exec CLI command mode.
4. Configure IP on an interface.
5. Copy the release files on the network host.
6. Configure access to the network host.
7. Enable the FTP server on the router.
8. Identify the files to transfer.
9. Transfer the files to the user space on the router.
10. Install the software release file to the system space on the router.
11. Save the current configuration.
