Installing a Junos Space Image on a Junos Space Appliance by Using a USB Drive

For Junos Space Platform Release 16.1R1 and later, the filename of the downloaded image is in the space-version.spin-number-usb.iso format, where version refers to the major version number and spin-number refers to the spin number within that release; for example, space-16.1R1.1-usb.iso.

• If you are using a computer with Windows as the operating system:

  1. Open the Win32 Disk Imager software, which was installed on your computer.

  2. In the Win32 Disk Imager window, click the Open or Browse icon, and in the subsequent dialog box, select the image file that you want to copy to the USB drive.

  3. In the Win32 Disk Imager window, verify that the drive letter displayed in the Device drop-down box matches the chosen USB drive. If a different drive letter is displayed, select the drive letter that matches the USB device from the Device list.

  4. Click Write, and in the confirmation dialog box that appears, click Yes.

     A progress bar in the Win32 Disk Image window displays the status; if the write operation is successful, a message is displayed.

  5. Click Exit to exit the Win32 Disk Imager window.

  6. Eject the USB drive and unplug it from the computer.

• If you are using a computer with Mac OS as the operating system:

  1. Open a shell (CLI).

  2. Use the cd command to go to the directory containing the software image file.

  3. Run the diskutil list command to determine the disk to which the USB is assigned.

     content_copy zoom_out_map

     [user@host ~]$ diskutil list
     

  4. Run diskutil unmountDisk /dev/diskN to unmount the disk.

     content_copy zoom_out_map

     [user@host ~] diskutil unmountDisk /dev/diskN

     where /dev/diskN is the disk to which the USB is assigned.

  5. For Junos Space Platform Release 16.1R1 and later, type the following command and press Enter:

     content_copy zoom_out_map

     [user@host ~]$ sudo dd if=space-version.spinnumber-usb.iso of=/dev/usb-drive

     where space-version.spin-number-usb.iso is the name of the downloaded Junos Space image file, and /dev/usb-drive is the name of the device drive to which your USB drive is mapped.

     Note:

     For releases prior to Junos Space Platform Release 16.1R1, type the following command to copy the image file to the USB drive and press Enter.

     content_copy zoom_out_map

     [user@host ~]$ sudo dd if=space-version.spinnumber.img of=/dev/usb-drive

     where space-version.spin-number.img is the name of the downloaded Junos Space image file, and /dev/usb-drive is the name of the device drive to which your USB drive is mapped.

     The image file is copied to the USB drive and you are taken to the command prompt.

  6. Unplug the USB drive from the computer.

• If you are using a computer with Linux as the operating system:

  Note:

  Although you can use any of the available tools, we recommend that you use the dd command in Linux to create a bootable USB drive.

  1. Open a shell (CLI).

  2. Use the cd command to go to the directory containing the software image file.

  3. Run the fdisk –l command to determine the disk to which the USB is assigned; for example, disk/sdb.

     content_copy zoom_out_map

     [user@host ~]$ disk –l

  4. For Junos Space Platform Release 16.1R1, type the following command and press Enter:

     content_copy zoom_out_map

     [user@host ~]$ dd if=space-version.spinnumber-usb.iso of=/dev/sdb

     where space-version.spin-number-usb.iso is the name of the downloaded Junos Space image file, and /dev/sdb is the name of the device drive to which your USB drive is mapped.

     Note:

     For releases prior to Junos Space Platform Release 16.1R1, type the following command to copy the image file to the USB drive and press Enter.

     content_copy zoom_out_map

     [user@host ~]$ dd if=space-version.spinnumber.img of=/dev/sdb

     where space-version.spin-number.img is the name of the downloaded Junos Space image file, and /dev/sdb is the name of the device drive to which your USB drive is mapped.

     The image file is copied to the USB drive and you are taken to the command prompt.

  5. Eject and unplug the USB drive from the computer.

1. Power on the appliance.

2. As soon as the appliance starts powering on, press the key that you have mapped to send the DEL character in the terminal emulation utility. In most cases, this would be the Backspace key.

   Note:

   If the hard disk LEDs begin to flash at this point for more than a few seconds, the appliance is booting from the hard disk instead of the USB drive, and the BIOS menu will not be loaded. In this case, you need to power down the appliance and repeat this step.

   If you are successful in accessing the BIOS setup, the boot menu appears after about one minute.

1. Use the down arrow to select USB KEY:CBM USB 2.0- (USB 2.0) and use the + key to move the entry to the top of the list.

2. Press the F10 key to save your changes and exit the BIOS setup.

   The appliance restarts and uses the new boot order, thereby booting from the USB drive. The boot prompt displays a menu, as follows:

   • reinstall

   • rescue-kvm

   • rescue-serial

   • local

   You can use the up and down arrows to move between the options. Press Enter to make your selection.

The reinstallation process takes approximately 2 hours and 30 minutes. When the installation is complete, the appliance powers down.

The appliance boots with the version of the Junos Space Network Management Platform that you installed.

You must configure the basic settings for your appliance before you can use it to manage devices. Refer to Configuring a Junos Space Appliance as a Junos Space Node and Configuring a Junos Space Appliance as a Standalone or Primary FMPM Node for details.
