JunOS EX2200 Firmware Upgrade

Since I have a EX2200, I thought I should at least upgrade its firmware. But JunOS firmware upgrade didn’t go as user-friendly as I thought. Anyways, this is what I did to upgrade from 11.1R3.5 to 12.3R12.4

Key Notes:

• Don’t use the Web Interface to upgrade. It is slow and does not seem to work.
• Upload the firmware to a web server that allows direct linking.
• The reboot process takes more than 15 minutes. Do not be alarmed if the switch seems to be dead during the process.

Steps via Cli

root@JunSwitch:RE:0% cli

root@JunSwitch> request system software add "Web Link here"
Fetching package...
/var/tmp/incoming-package.tgz                          748 kB  748 kBps
WARNING: A reboot is required to install the software
WARNING:     Use the 'request system reboot' command immediately

root@JunSwitch> request system reboot
Reboot the system ? [yes,no] (no) yes

Shutdown NOW!

root@JunSwitch> show version
