Converting a Satellite Device in a Junos Fusion to a Standalone Device

In the event that you need to convert a satellite device to a standalone device, you will need to download and install a new Junos OS software package on the satellite device. The satellite device stops participating in the Junos Fusion topology once the software installation starts.

The following steps explain how to convert a satellite device that is participating in a Junos Fusion to a standalone device running Junos OS. If you have a standalone switch that is not part of a Junos Fusion but is running satellite software, and you want the switch to run Junos OS software, see Installing Junos OS Software on a Standalone Device Running Satellite Software.

Note:

The QFX5100-48SH and QFX5100-48TH switch models are shipped from the factory with satellite device software. You cannot convert these switches to become standalone devices.

Conversion of EX2300 and EX3400 switches from satellite devices to standalone devices cannot be initiated from the aggregation device. To install Junos OS software on an EX2300 or EX3400 switch acting as a satellite device, see Installing Junos OS Software on a Standalone Device Running Satellite Software.

Download Junos OS Software

Before you install a new Junos OS software package on a satellite device, make sure you download the correct software package for that device:

  • If the satellite device is a QFX5110, QFX5200 or EX4300 switch, you install a standard, signed jinstall version of Junos OS.

  • If the satellite device is a QFX5100 switch that can be converted to a standalone device, you must install a Preboot eXecution Environment (PXE) version of Junos OS. The PXE version of Junos OS software supports the same feature set as the other Junos OS software packages for a release, but is specially engineered to install Junos OS onto a device running satellite software. The PXE Junos OS package name uses the format install-media-pxe-qfx-5-version-domestic.tgz.

  • For Junos Fusion systems running Junos OS Release 17.2R1 and later, if the satellite device is a QFX5100 switch that can be converted to a standalone device, you must install a signed PXE version of Junos OS to convert the satellite device running satellite software to a standalone device running Junos OS software. The signed PXE Junos OS package name uses the format install-media-pxe-qfx-5-version-domestic-signed.tgz.

To download the version of Junos OS that you want to run on the satellite device after removing it from the Junos Fusion:

  1. Using a Web browser, navigate to the Junos OS software download URL on the Juniper Networks webpage:

    https://www.juniper.net/support/downloads

  2. Log in to the Juniper Networks authentication system using the username (generally your e-mail address) and password supplied by Juniper Networks representatives.
  3. Select By Technology > Junos Platform > Junos Fusion from the drop-down list and select the switch platform series and model for your satellite device.
  4. Select the version of Junos OS that you want to run on the satellite device after removing it from the Junos Fusion.
  5. Review and accept the End User License Agreement.
  6. Download the software to a local host.
  7. Copy the software to the routing platform or to your internal software distribution site.

Disable the Automatic Conversion Configuration

Before removing a satellite device from an operational Junos Fusion, you must disable the configuration for automatic satellite conversion. If automatic satellite conversion is enabled for the FPC slot ID, the Junos OS installation cannot proceed.

For example, the following installation on an EX4300 satellite device is blocked:

You can check the automatic satellite conversion configuration by entering the show statement at the [edit chassis satellite-management auto-satellite-conversion] hierarchy level.

  1. If automatic satellite conversion is enabled for the satellite device’s FPC slot ID, remove the FPC slot ID from the automatic satellite conversion configuration.

    For example, to remove FPC slot ID 103 from the Junos Fusion.

  2. Commit the configuration.

    • To commit the configuration to a single Routing Engine only:

    • To commit the configuration to all Routing Engines in multiple-aggregation device topology:

Install Junos OS Software on the Satellite Device

  1. To install the Junos OS software on the satellite device to convert the device to a standalone device, use the following CLI command:

    For example, to install a software package stored in the var/tmp folder on the aggregation device onto an EX4300 switch acting as the satellite device using FPC slot 103:

    Note:

    If you are converting a QFX5100 switch and the Junos Fusion is running a Junos OS release earlier than 17.2R1, you must install the unsigned PXE software package on the QFX5100 switch:

    The satellite device stops participating in the Junos Fusion topology once the software installation starts. The software upgrade starts after this command is entered.

  2. To check the progress of the conversion, issue the show chassis satellite fpc-slot command:
  3. Wait for the reboot that accompanies the software installation to complete.
  4. When you are prompted to log back into your device, uncable the device from the Junos Fusion topology. See Remove a Transceiver. Your device has been removed from Junos Fusion.
    Note:

    The device uses a factory-default configuration after the Junos OS installation is complete.

17.2R1
For Junos Fusion systems running Junos OS Release 17.2R1 and later, if the satellite device is a QFX5100 switch that can be converted to a standalone device, you must install a signed PXE version of Junos OS to convert the satellite device running satellite software to a standalone device running Junos OS software.
