Reimaging and Relicensing an Appliance
The appliance comes with software preinstalled. If needed, you can reinstall the factory
image. This process is known as reimaging the appliance. The reimaging process rewrites
the disk except for the partition containing /var/idp. If necessary and if possible, you
should save a copy of data or custom configuration files before reimaging.
If you reimage the appliance, you must also relicense it.
To reimage the appliance:
1. Connect a PC to the console serial port of the device, using the serial cable provided
with the appliance.
2. Power off the appliance.
3. Insert the USB flash memory stick that shipped with the appliance into the USB port
on the front of the appliance. If you have misplaced your USB flash memory stick,
contact Juniper Networks Technical Assistance Center (JTAC). The part number for
the USB flash memory stick is IDP-FLASH (IDP75, IDP250, IDP800) or
IDP-FLASH-8200 (IDP8200).
4. Power on the appliance.
The appliance boots from the USB stick and runs the reimaging process. Follow any
prompts on the serial console.
5. When the reimaging process has completed, remove the USB stick and reboot.
Next Steps 1. Configure the appliance as if a new installation.
2. Relicense the appliance.
3. Re-add the appliance to NSM.
4. Push updates to detector engine, attack object, and security policy.
