NOTE: We recommend that you install two host subsystems for redundant
protection. If you install only one host subsystem, we recommend that you
install it in slot

Each host subsystem has three LEDs, located on the upper right of the craft interface,
that display its status. In addition, there are LEDs on each Routing Engine and control
board..

T1600 Routing Engine Description
The Routing Engine runs the Junos OS. Software processes that run on the Routing Engine
maintain the routing tables, manage the routing protocols used on the T1600 Core Router,
control the T1600 router interfaces, control some chassis components, and provide the
interface for system management and user access to the router.
You can install one or two Routing Engines in the router. The Routing Engines install into
the upper rear of the chassis in the slots labeled
a control board to be installed in the adjacent slot.
installs above CB1 . A Routing Engine does not power up without a control board present
in the adjacent slot.
If two Routing Engines are installed, one functions as the master and the other acts as
the backup. If the master Routing Engine fails or is removed and the backup is configured
appropriately, the backup takes over as the master. If the host system is redundant, the
backup Routing Engine is hot-removable and hot-insertable, but the master Routing
Engine is hot-pluggable. A Routing Engine that is not redundant requires that you power
down the router before replacement.
