Firmware Update From USB

Actualización mediante USB

Enter the shell:

user@srx> start shell
%

Antes de insertar el dispositivo USB, ejecute lo siguiente:

% ls /dev/da*
/dev/da0        /dev/da0s1c     /dev/da0s2c     /dev/da0s3e     /dev/da0s4a
/dev/da0s1      /dev/da0s2      /dev/da0s3      /dev/da0s3f     /dev/da0s4c
/dev/da0s1a     /dev/da0s2a     /dev/da0s3c     /dev/da0s4      /dev/da0s4e

Inserte el dispositivo en el puerto USB. Se debería ver en la consola algo similar a lo siguiente:

ls /dev/da*
/dev/da0        /dev/da0s2      /dev/da0s3c     /dev/da0s4a     /dev/da1s1
/dev/da0s1      /dev/da0s2a     /dev/da0s3e     /dev/da0s4c
/dev/da0s1a     /dev/da0s2c     /dev/da0s3f     /dev/da0s4e
/dev/da0s1c     /dev/da0s3      /dev/da0s4      /dev/da1

 

Note : '/dev/da1s1' is the USB drive.

Create a directory for the USB drive to mount to:

  % mkdir /var/tmp/usb

 

Mount the USB drive to the /var/tmp/usb directory:

%su
Password:
root@srx% mount_msdosfs /dev/da1s1 /var/tmp/usb
root@srx% ls /var/tmp/usb
junos-srxsme-18.4r3-s2.tgz

 

Note : ls /var/tmp/usb will show all the files in the USB drive. ​

Copy any of the USB files to the /var/tmp/usb directory:

root@srx% cp /var/tmp/usb/junos-srxsme-18.4r3-s2.tgz /var/tmp
root@srx% ls /var/tmp
junos-srxsme-18.4r3-s2.tgz

 

The junos-srxsme-18.4r3-s2.tgz file from the USB is successfully copied to the /var/tmp directory.

Now unmount the USB drive after the file is completely copied:

root@srx% umount /var/tmp/usb
root@srx% exit
%exit

 

Note: ​For devices with multiple USBs, make sure that you unmount both devices.
