Step-by-step:
- Connect to the router's console as root user (the prompt looks like this:
root>)- (If, right after login, you already are in shell mode (
root@%) and theexitcommand will only log you out instead of bringing you into command mode (root>), you can issue theclicommand to get there.)
- (If, right after login, you already are in shell mode (
- Check the current software version:
show version - Start a shell session:
start shell(the prompt changes toroot@%) - Create a temporary folder and mount the USB drive:
mkdir /mnt/usb(if you get the message "read-only file system", then trymkdir /tmp/usb)- Put the
jinstall-*.tgzfile on a FAT32 formatted USB drive and place it in the router's USB port - Watch the message on the screen to find out what device references the USB drive (e.g.
da1s1) mount -t msdosfs /dev/da1s1 /mnt/usb(if you get the message "Operation not permitted, try a different USB drive (i.e. a different manufacturer))
- Copy the
jinstallfile 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/
- Example:
- 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 toroot>) - 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
- Example:
- Reboot the router:
request system reboot - Check the new software version has been installed:
show version
