SRX Junos 系统安装更新之一（U盘安装）

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:
   

   [email protected]> start shell
[email protected]% 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: <USB USBFlashDrive 0100> 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

   [email protected]% ls /dev/

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

4. Create a mount directory:
   

   [email protected]% mkdir /tmp/usb

5. Mount the USB to the directory:
   

   [email protected]% mount -t msdosfs /dev/<drivelabel, e.g. #da0s1> /tmp/usb

   Example:
   [email protected]% 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:
   [email protected]% pwd
/cf/root
[email protected]% cd /tmp/usb/
[email protected]% pwd
/cf/tmp/usb
[email protected]% ls
junos-jsr-11.4R5.7-export.tgz 


6. Exit shell and install the software:
   

   [email protected]% exit
[email protected]> request system software add /tmp/usb/<upgrade filename> 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:
   

   [email protected]> request system reboot
