Removing a Satellite Device from a Junos Fusion
This topic discusses the recommended method of removing a satellite device from an operational Junos Fusion. A version of Junos OS is installed onto the satellite device as part of this procedure.
Before you begin:
Select the version of Junos OS that you want to run on the satellite device after removing it from the Junos Fusion. and download it.
See Understanding Junos Fusion Enterprise Software and Hardware Requirements for Junos OS requirements in satellite software to Junos OS conversions.
See Downloading Software for software download instructions.
To remove a satellite device from an operational Junos Fusion:
- 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.
[edit]
user@aggregation-device# delete chassis satellite-management auto-satellite-conversion satellite slot-idFor example, to remove FPC slot ID 101 from the Junos Fusion.
[edit]
user@aggregation-device# delete chassis satellite-management auto-satellite-conversion satellite 101If automatic satellite conversion is enabled for the FPC slot ID, the Junos Fusion tries to convert the device back into a satellite device later in this procedure.
You can check the automatic satellite conversion configuration by entering the show statement at the [edit chassis satellite-management auto-satellite-conversion] hierarchy level.
- Commit the configuration to both Routing Engines:

user@aggregation-device# commit synchronizeIf you want to commit the configuration to a single Routing Engine only:
[edit]
user@aggregation-device# commit - Start the standalone Junos conversion process by installing
Junos OS onto the satellite device.
For EX2300 and EX3400 switches, log in to the satellite software (SNOS) on the switch to be converted back to Junos OS and use the following sequence of commands to install the Junos package:
####################################### dd bs=512 count=1 if=/dev/zero of=/dev/sda echo -e "o\nn\np\n1\n\n\nw" | fdisk /dev/sda mkfs.vfat /dev/sda1 fw_setenv target_os reboot ################################## >>Get to the loader prompt ################################## loader> install --format tftp://<tftp server>/<Junos package name>
For EX4300 and QFX5100 switches, issue the following command:
user@aggregation-device> request chassis satellite install URL-to-software-package fpc-slot slot-id
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 101:
user@aggregation-device> request chassis satellite install /var/tmp/jinstall-ex-4300-14.1X53-D40.8-domestic-signed.tgz fpc-slot 101
To perform the same process for a QFX5100 switch acting as a satellite device in FPC slot 102:
user@aggregation-device> request chassis satellite install /var/tmp/install-media-pxe-qfx-5-14.1X53-D43.2-domestic-signed.tgz fpc-slot 102
Note On a QFX5100 switch acting as a satellite device, you must install a Preboot eXecution Environment (PXE) version of Junos OS to convert the satellite device running satellite software to a standalone device running Junos OS software.
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 version of Junos OS includes pxe in the package name when it is downloaded from the Software Center—for example, the PXE image for Junos OS Release 14.1X53-D40 is named install-media-pxe-qfx-5-14.1X53-D43.3-domestic-signed.tgz.
For Junos Fusion systems running Junos OS Release 17.2R1 and later, 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
.The satellite device stops participating in the Junos Fusion once the software installation starts. The software upgrade starts after this command is entered.
- Wait for the reboot that accompanies the software installation to complete.
- When you are prompted to log back into your device, uncable the device from the Junos Fusion. See Removing a Transceiver or Removing a Transceiver from a QFX Series Device, as needed.
Your device has been removed from the Junos Fusion.
The device uses a factory-default configuration after the Junos OS installation is complete.
