EX Series switch downloads and installs the software package specified in the DHCP
server message.
Before you upgrade software using automatic software download, ensure that you have
configured DHCP services for the switch, including configuring a path to a boot server
and a boot file. See the
Junos OS System Basics Configuration Guide
at
http://www.juniper.net/techpubs/software/junos/index.html
for information about using
the CLI to configure DHCP services and settings. See “Configuring DHCP Services (J-Web
Procedure)” on page 549 for information about using the J-Web interface to configure
DHCP services and settings.
To enable automatic software download on an EX Series switch acting as a DHCP client:
[edit chassis]
user@switch# set auto-image-upgrade
Once automatic software download is enabled on your DHCP client EX Series switch
and once DHCP services are enabled on your network, an automatic software download
can occur at any time as part of the DHCP message exchange process.
If an automatic software download occurs, you see the following message on the switch:
Auto-image upgrade started
On successful installation system will reboot automatically
The switch reboots automatically to complete the upgrade.

Managing Licenses for the EX Series Switch (CLI Procedure)
To enable and use some Junos OS features on an EX Series switch, you must purchase,
install, and manage separate software licenses. Each switch requires one license. For a
Virtual Chassis deployment, two licenses are recommended for redundancy. After you
have configured the features, you see a warning message if the switch does not have a
license for the feature.
Before you begin managing licenses, be sure that you have:
•
Obtained the needed licenses. For information about how to purchase software licenses,
contact your Juniper Networks sales representative.
