RE-S-X6-64G Routing Engine Description on page 65
In a nonredundant host subsystem, only one Routing Engine and one Switch Control
Board are present in the chassis. When you are upgrading the Routing Engine, taking the
host subsystem offline shuts down the router. To upgrade the host subsystem with the
RE-S-X6-64G Routing Engine, you must uninstall the existing Routing Engine and install
the RE-S-X6-64G Routing Engine. Ensure that the Switch Control Board in the chassis
is SCBE2 because the RE-S-X6-64G Routing Engine is not compatible with the Switch
Control Boards SCB or SCBE. To upgrade the Switch Control Board to SCBE2, see
