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.
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:
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:
[edit] user@aggregation-device> request chassis satellite install fpc-slot 103 /var/tmp/jinstall-ex-4300-14.1X53-D43.7-domestic-signed.tgz Convert satellite device to Junos standalone device? [yes,no] (no) yes
