    Installing an NSM4000 ISO Image on the NSM4000 Appliance Using a USB Drive

    You can install an NSM4000 ISO image on the NSM4000 appliance using a standard USB 2.0 and USB 3.0 drive. You can use this procedure to either reinstall the current NSM4000 ISO image or revert to the factory default version on the NSM4000 appliance.

    Note:

    • The NSM4000 appliance is shipped with NSM 2012.2R7 already installed on it.
    • We recommend that you install only NSM 2012.2R7 or later versions on the NSM4000 appliance.

    Before you begin, ensure that:

    • You have a laptop or PC (running Windows) that is connected to the Internet.
    • You install the Rufus software on your computer to enable the software image to be written on the USB drive. You can download this software for free from http://rufus.akeo.ie/.
    • You have a USB drive with at least 2 GB of free space for images.
    • You can connect to the NSM4000 appliance using the management console.
    • You have configured a console terminal or terminal emulation utility to use the following serial connection parameters:
      • Baud rate: 9600 bits per second
      • Data: 8 bits
      • Flow control: None
      • Parity: None
      • Stop bits: 1

      Note: The console terminal or terminal emulation utility maps every key on the keyboard to a code that it then sends through the management console. In some cases, the Delete key on a PC keyboard does not send a DEL or Control-? character. You must ensure that the terminal utility that you are using to connect to the NSM4000 appliance maps a key to the DEL or Control-? character. Typically, this is accomplished by configuring the terminal utility to send a DEL or Control-? character when the Backspace key on the keyboard is pressed.

    Installing an NSM4000 ISO Image on the NSM4000 appliance using a USB drive involves the following steps:

    Downloading the NSM4000 ISO Image from the Juniper Networks Support Site

    This section provides the information necessary to download the NSM4000 ISO image from the Juniper Networks support site.

    To download the NSM4000 ISO image:

    1. Plug the USB drive to the USB port of a laptop or PC that is connected to the Internet.
    2. Using a Web browser, navigate to the Juniper Networks software download site (https://www.juniper.net/support/downloads/), and click Network Management > Network & Security Manager.
    3. On the subsequent page, click the Software tab and then click NSM4000 Appliance ISO CentOS6.5_v1 under Tools to download the NSM4000 ISO image.

      The filename of the downloaded image is in the NSM4000_RS_CentOS_version_vspin-number.iso format, where version refers to the CentOS version number and spin-number refers to the ISO release spin number; for example, CentOS_6.5_v1.0.iso.

      Caution: Do not modify the filename of the software image that you download from the Juniper Networks support site. If you modify the filename, the installation fails.

    Creating a Bootable USB Drive

    This section provides the information necessary to create a bootable USB drive using Rufus, a third-party software utility, and copy the NSM4000 ISO image file.

    If the USB drive has files that you would like to keep, save the files to your PC or laptop.

    Note: The bootable USB drive that you create using these procedures will not be usable as a normal USB drive. If you want to use the USB drive for storing files, you must reformat the drive.

    To create a bootable USB drive:

    1. Connect the USB drive to your computer.
    2. Open the Rufus software that you previously installed on your computer.

      (You can download the Rufus software for free from http://rufus.akeo.ie/.)

    3. Perform the following steps in the Rufus window. The Rufus window appears as shown in Figure 1.

      1. 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.
      2. In the drop-down menu near the bottom of the window, to the right of the Create a bootable disk using check box, select ISO Image.
      3. On that same line, to the right of the ISO Image drop-down menu, click the CD-ROM icon.
      4. Select the NSM4000 ISO image file that you want to copy to the USB drive.
      5. Click Start.
      6. Click OK in the Warning dialog box to format the USB drive and copy the NSM4000 ISO image. See Figure 2.

        Figure 2: Rufus Warning Dialog Box

        Rufus Warning Dialog Box

        A progress bar in the Rufus window displays the status; if the start operation is successful, a message is displayed.

      7. Click Close to exit the Rufus window. Figure 3 displays the Rufus window as it appears after you have successfully created a bootable USB drive.

    4. Eject the USB drive, and unplug it from the computer.

    Ensuring that the NSM4000 Appliance’s BIOS Boots from the USB Drive

    This section provides the information necessary to boot the NSM4000 appliance from the USB drive that contains a copy of the NSM4000 ISO image file.

    To boot the NSM4000 appliance from the USB drive:

    1. Plug the USB drive into the USB port of the NSM4000 appliance on which you want to install the software image.

      Note: To install the software image from the USB drive, the boot priority order in the NSM4000 appliance must have USB boot at the top. By default, the NSM4000 appliance attempts to boot from the USB drive first and then from the RAID volume or hard drive. However, if you have changed the default boot order in the BIOS of the NSM4000 appliance, you must access the boot menu and change the boot order to make USB the first option. You do this by pressing the DEL or Control-? character three times as soon as you power the on the NSM4000 appliance.

    2. To access the NSM4000 appliance boot menu:
      1. Power on the NSM4000 appliance.
      2. As soon as the NSM4000 appliance starts powering on, press the key that you have mapped in the terminal emulation utility to send the DEL character. In a few 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 NSM4000 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 NSM4000 appliance and repeat this step.

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

    3. Ensure that the USB boot is at the top of the NSM4000 appliance boot priority order. If the USB label is not at the top of the list:
      • Use the down arrow to select the USB label and use the + key to move the entry to the top of the list.
      • Press the F10 key to save your changes and exit the BIOS setup.

        The NSM4000 appliance automatically restarts and uses the new boot order, thereby booting from the USB drive.

    Installing the NSM4000 ISO Image on the NSM4000 Appliance

    This section provides the information necessary to install the NSM4000 ISO Image using the USB drive on the NSM4000 appliance.

    The boot prompt displays the NSM4000 appliance installation menu as displayed in Figure 4.

    Figure 4: NSM4000 Appliance Installer Boot Prompt

     NSM4000 Appliance Installer Boot Prompt

    Warning: The usb-reinstall command explained in the next step overwrites your hard disk drive with a new factory default NSM4000 installation, erasing the previous installation and configuration. If you do not want to proceed, power off the NSM4000 appliance immediately.

    To install the NSM4000 ISO Image using the USB drive:

    1. At the boot prompt, type usb-reinstall and press Enter.

      Note: If no input is provided for 30 seconds, the NSM4000 appliance boots from the local disk by default.

    2. Remove the USB drive while the NSM4000 appliance is rebooting, approximately 1 hour and 15 minutes into the reinstallation process.

      Note: Because the NSM4000 appliance boot order was changed earlier in this procedure, the NSM4000 appliance will try to boot from the USB drive before choosing the next option. You can revert to boot from the local disk using the method explained in Ensuring that the NSM4000 Appliance’s BIOS Boots from the USB Drive.

      The NSM4000 appliance boots from the local disk and continues the reinstallation process. The installation wizard freezes at the Starting NSM installation – This might take a while to complete screen for approximately 30-35 minutes. After the reinstallation is complete, the serial console displays the following terminal emulator login prompt.
