Installing Junos OS Software on a Standalone Device Running Satellite Software
This process should be used when you have a standalone switch running satellite software and you want the switch to run Junos OS software. A standalone device is running satellite software for one of the following reasons:
It was removed from a Junos Fusion without following the instructions in Converting a Satellite Device in a Junos Fusion to a Standalone Device, which include a Junos OS installation.
Satellite software was installed on the device but the device was never provisioned into a Junos Fusion.
If you are removing a satellite device from a Junos Fusion, you must first make sure that automatic satellite conversion is disabled for the satellite device’s FPC slot ID. See Converting a Satellite Device in a Junos Fusion to a Standalone Device.
To install Junos OS onto a QFX5100, QFX5100 or QFX5200 switch running satellite software:
- Select a Junos OS image that meets the satellite software to Junos OS conversion requirements. See Junos Fusion Hardware and Software Compatibility Matrices for satellite software to Junos OS conversion requirements.
- Copy the Junos OS image onto a USB flash drive and use the USB flash drive to install the Junos OS. See Performing a Recovery Installation Using an Emergency Boot Device.
To install Junos OS onto an EX4300 switch running satellite software:
Log in to the console port of your switch.
Power off the switch, and power it back on.
While the switch is powering back on, enter the UBoot prompt (=>) by pressing Ctrl+C on your keyboard.
From the Uboot prompt, set the operating system environment mode on the switch to Junos. Save the configuration and reset the kernel:
=> setenv osmode junos => setenv snos_previous_boot 0 => save => reset
After the reset operation completes, the loader prompt (
loader>) appears.Install Junos OS using a USB flash drive from the loader prompt. See Booting an EX Series Switch Using a Software Package Stored on a USB Flash Drive.
To install Junos OS onto an EX2300 or EX3400 switch running satellite software:
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>
