root@:RE:0% cd /var/tmp
root@:RE:0% mkdir usb

Вставляємо флешку де записано прошивку, монтуємо її та копіюємо firmware:

root@:RE:0% ls -l /dev/da1*
crw-r-----  1 root  operator    0,  83 Jun 25 18:23 /dev/da1
crw-r-----  1 root  operator    0,  84 Jun 25 18:23 /dev/da1s1
root@:RE:0% mount_msdosfs /dev/da1s1 usb
root@:RE:0% cp usb/jinstall-ex-2200-12.3R10.2-domestic-signed.tgz .
root@:RE:0% umount /var/tmp/usb

Переходимо у cli та оновлюємось:

root@:RE:0% cli
root> request system software add jinstall-ex-2200-12.3R10.2-domestic-signed.tgz
root> request system reboot

Оновлюємось. Після того як все закінчиться знову заходимо у систему.
