Installing Junos Continuity Software Package to Support New Hardware
Before you begin installing Junos Continuity software:
Download the Junos Continuity software package from https://www.juniper.net/support/. For information about downloading software packages, see Downloading Software.
Install the new line cards by following the procedure given in the router’s hardware guide.
(Optional) Run the
run show chassis fpccommand to verify the status of the new line cards.For example, the following sample output displays information about all the line cards installed on the router:
[edit] user@router# run show chassis fpc Temp CPU Utilization (%) CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt 1min 5min 15min DRAM (MB) Heap Buffer 0 Empty 1 Empty 2 Empty ... 16 Empty 17 Empty 18 Empty 19 Offline ---FPC incompatible with SCB---The newly installed line cards are displayed as
FPC incompatible with SCBbecause the router cannot recognize them.

You install the Junos Continuity software package to enable a router to support new hardware without the need to upgrade Junos OS. You can install the Junos Continuity software package as a standalone package or as a package bundled with Junos OS.
If graceful Routing Engine switchover (GRES) is enabled, you must install the Junos Continuity software package on both the primary and the backup Routing Engines to ensure that the hardware components remain operational after a Routing Engine switchover.
Before you proceed with the installation, verify that the version of Junos OS that is installed on the router supports Junos Continuity software.
You can consider one of the following methods to install Junos Continuity software:
Install the Standalone Junos Continuity Plug-in—Upgrade of Junos OS is not required. You install the Standalone Junos Continuity Plug-in if the version of Junos OS that is installed on the router supports Junos Continuity software. For example, if the router is running Junos OS Release 15.1F4, you can directly install Standalone Junos Continuity Plug-in and then bring the line cards online.
After you install Junos Continuity software, you can bring the new line card online by using the
request chassis fpc slot-number onlinecommand.This topic guides you through the installation of the Standalone Junos Continuity Plug-in on 64-bit Junos OS.
Install the Junos Continuity Plug-in Integrated with Junos OS—Requires you to upgrade Junos OS. You use the integrated package if the version of Junos OS that is installed on the router does not support Junos Continuity software. For example, if you want to install Junos Continuity software on Junos OS Release 13.3, you can use the integrated package that contains both Junos OS Release 15.1F4 and the Junos Continuity Plug-in. This is a one-step process to upgrade Junos OS to Junos OS Release 15.1F4 and also to install Junos Continuity software. See Software Installation and Upgrade Guide for more information about upgrading Junos OS.
To upgrade the Junos Continuity software package, you can just install the new package on the router. The installed version of Junos Continuity software gets overwritten when you install a later version.
