This procedure describes how to boot and reinstall Junos OS on a Director group with
access to the QFabric system default partition:
1. Ensure that you have an emergency boot device (external USB device) to use during
the installation.
2. Log in to the QFabric system default partition.
3. To download the software from the external USB device, issue the request system
software download command and specify the path and the package name on the
external USB device:
request system software download /media/usbdisk/jinstall-qfabric-11.3R1.4.rpm
4. To install the software, issue the requestsystem software add package-name component
director-group reboot command and specify the name of the software package:
request system software add jinstall-qfabric-11.3R1.4.rpm component director-group
reboot
The Director group copies the software from the external USB device, occasionally
displaying status messages. Copying the software can take up to 10 minutes.
5. Remove the external USB device when prompted, and then press Enter.
The Director group then reboots from the internal flash storage on which the software
was just installed. When the reboot is complete, the Director group displays the login
prompt.
6. Create a new configuration as you did when the Director group was shipped from the
factory, or restore the previously saved configuration file to the Director group.
