Download the 64-bit software package from the Juniper Networks Support website
at http://www.juniper.net/support/. Under Download Software, select either Junos
(US & Canada) or Junos (Worldwide).
To download the software package, you must have a service contract and an access
account. If you need help obtaining an account, complete the registration form at the
Juniper Networks website: https://www.juniper.net/registration/Register.jsp.
Installing 64-Bit Junos OS
To install 64-bit Junos OS:
1. Back up the currently running file system so that you can recover to a known, stable
environment in case something goes wrong with the upgrade:
user@host>request system snapshot
The root file system is backed up to /altroot, and /config is backed up to /altconfig.
The root and /config file systems are on the router’s CompactFlash card, and the
/altroot and /altconfig file systems are on the router’s hard disk.
NOTE: After you issue the request system snapshot command, you cannot
return to the previous version of the software, because the running copy
and the backup copy of the software are identical.
2. Copy the downloaded software package to the /var/tmp directory on the hard disk:
user@host> file copy ftp://username:prompt@ftp.hostname.net/filename /var/tmp
3. Add the new software package:
user@host> request system software add/var/tmp/ installation-package validate
installation-package is the full name of the file copied in the previous step. For 64-bit
Junos OS, the full name would be jinstall64.tgz.
The system might display the following message:
pkg_delete: couldn’t entirely delete package
This message indicates that someone manually deleted or changed an item that was
in a package. You do not need to take any action; the package is still properly deleted.
4. Reboot the router to start the new software:
user@host> request system reboot
5. After you have upgraded the software and are satisfied that the new software is
properly running, issue the request system snapshot command to back up the new
software:
user@host> request system snapshot
The root file system is backed up to /altroot, and /config is backed up to /altconfig. The
root and /config file systems are on the router’s CompactFlash card, and the /altroot and
/altconfig file systems are on the router’s hard disk.
