Upgrading an MX480 to Use the SCBE-MX
This topic describes how to upgrade your MX960, MX480, or MX240 router to use the
SCBE-MX without taking the router offline. This “in-service” upgrade only works for MX
routers with DPC, MS-DPC, MPC1, MPC2, or MPC3 line cards. If your MX router has another
type of line card, you’ll need to take the router offline before you do the upgrade.
NOTE: Junos OS does not support in-service upgrades to the SCBE-MX on
routers with an MX-MPC3E-3D or MX-MPC3-3D MPC. If your MX router has
these MPCs, you’ll need to shutdown the system before you do the upgrade.
An in-service upgrade can result in service disruption.

Complete the SCBE-MX Upgrade on page 341
Prepare for the Upgrade
Before you do the upgrade, open a telnet session to the master Routing Engine CLI
operational mode and issue the
configure exclusive
command. This command locks the
configuration to prevent accidental changes during the upgrade process.
