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
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.
If one CB-REs fails, do not remove the failed CB-RE until you have a replacement or blank panel to install.
The MX2000 line of routers supports the following CB-RE’s:
REMX2K-X8-64G-LT CB-RE has limited encryption support.
