MX2000 Host Subsystem CB-RE Description
The CB-RE is a combined Routing Engine and Control Board in one unit. It performs the following functions:
•
Maintains the routing tables
•
Manages the routing protocols used on the router
•
Controls the router interfaces
•
Controls some chassis components
•
Provides the interface for system management and user access to the route
The CB-RE is hot-pluggable and installs into the front of the MX2000 chassis in vertical slots labeled 0
and 1. A USB port on the CB-RE accepts a USB memory device that allows you to load Junos OS. You can
install one or two CB-REs in the router. If two CB-REs are installed, one functions as the master and the
other acts as the backup. If the master CB-RE fails or is removed and the backup is configured appropriately,
the backup takes over as the master. If no CB-RE is installed in a slot, install a blank panel in the slot.
A minimum of one CB-RE must be installed in either slot 0 or slot 1 at all times.
CAUTION:
If one CB-REs fails, do not remove the failed CB-RE until you have a
replacement or blank panel to install.
