Installing JUNOSe Software B-2
router in the network. Depending on the network configuration, you can
copy the release files from either the network host or the first E-series
router to the other E-series routers in the network (see
Copying Release
Files from One E-Series Router to Another ) .
Identifying the Software Release File
The JUNOSe software CD contains two software releases: one for the
ERX-1440 model and one for all other E-series routers. Both releases are
in the software directory, which is identified by the release number. For
example, if the release number is x.y.z, the name of the directory is x-y-z.
To identify the software release file:
1
Access the software directory.
2
Find the files with the extension .rel.
• The software release file for the ERX-1440 router has the format
erx40_x-y-z.rel, where x-y-z is the release number.
• The software release file for all other E-series routers has the
format erx_x-y-z.rel, where x-y-z is the release number.
The procedures outlined in the following sections provide detailed
instructions for typical installations. For additional information about
commands and troubleshooting, see the
E-Series System Basics
Configuration Guide , the E-Series Command Reference Guide A to M ,
and the E-Series Command Reference Guide N to Z .
Installing Software When a Firewall Exists
When a firewall separates the E-series router from the network host, you
must use FTP to transfer the software release files from the network host
to the E-series router. In this case, you must configure the FTP server on
the E-series 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 E-series router to support Telnet, then you
must use the local console. See
Chapter 8, Accessing E-Series Routers , for
information on using a local console or a Telnet session.
