NOTE: Router performance might change if the backup CB-REs configuration
differs from the former master's configuration. For the most predictable
performance, configure the two CB-RE identically, except for parameters
unique to each Routing Engine.
To configure the Routing Engine on the Control Board (CB-RE)—specific parameters and
still use the same configuration on both Routing Engines on the Control Board, include
the appropriate configuration statements under the
groups ] hierarchy level, and use the
Junos OS Administration Library for Routing Devices.
NOTE: For information about configuring graceful Routing Engine on the
CB-RE switchover, graceful restart, and nonstop active routing, see the Junos
OS High Availability Library for Routing Devices.
NOTE: The first supported release for both graceful Routing Engine on the
CB-RE switchover and nonstop active routing on the router is Junos OS
Release 12.3R2. Graceful restart software requirements depend on the routing
protocols configured on the router. For the minimum software requirements
for graceful restart, see the Junos OS High Availability Library for Routing
Devices.

When carrying an MPC, you can hold it either vertically or horizontally.
NOTE: A typical MPC can weigh 25 lb (11.34 kg) or more. Be prepared to
accept the full weight of the MPC as you lift it.
To hold an MPC vertically:
Orient the MPC so that the faceplate faces you. To verify orientation, confirm that the
1.
text on the MPC is right-side up and the electromagnetic interference (EMI) strip is
on the right-hand side.
Place one hand around the MPC faceplate about a quarter of the way down from the
2.
top edge. To avoid deforming the EMI shielding strip, do not press hard on it.
