Follow these steps to install the software via the CLI from a USB stick:

  1. Download the Junos upgrade file to the USB stick.  

  2. Locate the USB device ID that Junos is associating to the USB stick: 

    user@srx> start shell
    user@srx% ls /dev/

  3. Insert the USB device into the USB slot.  For example, slot 0 would return the following:

    root# umass0: USB USBFlashDrive, rev 2.00/1.00, addr 2
    da0 at umass-sim0 bus 0 target 0 lun 0
    da0: Removable Direct Access SCSI-0 device
    da0: 1.000MB/s transfers
    da0: 980MB (2007040 512 byte sectors: 64H 32S/T 980C)
    Run the following command

    user@srx% ls /dev/

    Locate difference in outputs to locate drive label. (It will usually be da#s1, i.e. da0s1)

  4. Create a mount directory:

    user@srx% mkdir /tmp/usb

  5. Mount the USB to the directory:

    user@srx% mount -t msdosfs /dev/ /tmp/usb
    Example:
    user@srx% mount -t msdosfs /dev/da0s1 /tmp/usb (there is a space between the label name and /tmp)

    Verify that the USB is mounted to the device:
    root@% pwd
    /cf/root
    root@% cd /tmp/usb/
    root@% pwd
    /cf/tmp/usb
    root@% ls
    junos-jsr-11.4R5.7-export.tgz 

  6. Exit shell and install the software:

    user@srx% exit
    user@srx> request system software add /tmp/usb/ no-validate no-copy

    For additional details regarding a software installation, refer to the instructions at Installing the Software.

  7. Upon completion, reboot the SRX:

    user@srx> request system reboot
