Step-by-step:

Put the jinstall-*.tgz file on a FAT32 formatted USB drive and place it in the router's USB port
Connect to the router's console as root user (the prompt looks like this: root> )
Check the current software version: show version
Start a shell session: start shell (the prompt changes to root@% )
Create a temporary folder and mount the USB drive:
- mkdir /mnt/usb
- mount -t msdosfs /dev/da1s1 /mnt/usb
Copy the jinstall file to the local file system:
- Example: cp /mnt/usb/jinstall-ppc-14.2R7.5-domestic-signed.tgz /var/tmp/
- Example: cp /mnt/usb/jinstall-ppc-15.1R5.5-domestic-signed.tgz /var/tmp/
Unmount the USB drive and unplug it: umount /mnt/usb
Exit the shell session to go back to command mode: exit (the prompt changes back to root> )
Install the software with the command request system software add:
- Example: request system software add /var/tmp/jinstall-ppc-14.2R7.5-domestic-signed.tgz
- Example: request system software add /var/tmp/jinstall-ppc-15.1R5.5-domestic-signed.tgz
- Example: request system software add /var/tmp/jinstall-ppc-15.1R6.7-domestic-signed.tgz
Reboot the router: request system reboot
Check the new software version has been installed: show version
