Installing Software on an EX Series Switch with a Single Routing Engine (CLI Procedure)
You can use this procedure to upgrade the Junos OS on an EX Series switch with a single
Routing Engine, including an individual member of a Virtual Chassis or all members of a
Virtual Chassis, or an EX8200 switch using a single Routing Engine. To upgrade software
on an EX8200 switch running two Routing Engines, see “Installing Software on an EX8200
Switch with Redundant Routing Engines (CLI Procedure)” on page 79.
To install software upgrades on an EX Series switch with a single Routing Engine using
the CLI:
1.
Download the software package as described in “Downloading Software Packages
from Juniper Networks” on page 77.
2.
(Optional) Back up the current software configuration to a second storage option.
See the
Junos OS Installation and Upgrade Guide
at
http://www.juniper.net/techpubs/software/junos/index.html
for instructions on
performing this task.
3.
(Optional) Copy the software package to the switch. We recommend that you use
FTP to copy the file to the
/var/tmp
directory.
This step is optional because the Junos OS can also be upgraded when the software
image is stored at a remote location. These instructions describe the software upgrade
process for both scenarios.
4.
Install the new package on the switch:
NOTE:
A reboot, which will occur as part of the execution of the following
command, is required to complete the software upgrade. If you want to
reboot the switch at a later time, do not use the reboot option at this point
of the procedure and enter the request system reboot command at a later
time to reboot the switch.
user@switch> request system software add source reboot
Replace
source
with one of the following paths:
•
For a software package that is installed from a local directory on the
switch—
/pathname/package-name-m.nZx-distribution.tgz
.
•
For a software package that is downloaded and installed from a remote location:
•
ftp://hostname/pathname/package-name-m.nZx-distribution.tgz
•
http://hostname/pathname/package-name-m.nZx-distribution.tgz
where
package-name-m.nZx-distribution
.tgz is, for example,
jinstall-ex-4200-9.4R1.8-domestic-signed.tgz
.
