SCB LEDs

Three LEDs on the SCB indicate the status of the SCB. The LEDs, labeled
ACTIVE
19 describes the functions of the SCB LEDs.

Routing Engine

The Routing Engine is an Intel-based PC platform that runs JUNOS software. Software
processes that run on the Routing Engine maintain the routing tables, manage the
routing protocols used on the device, control the device interfaces, control some
chassis components, and provide the interface for system management and user
access to the device.
You can install only one Routing Engine in the device. The Routing Engine installs
into the front of the chassis in the horizontal slot in the SCB labeled
A USB port on the Routing Engine accepts a USB memory card that allows you to
load JUNOS software.
Control FPGA—Provides the Peripheral Component Interconnect (PCI) interface
to the Routing Engine.
1000Base-T Ethernet controller—Provides a 1-Gbps Ethernet link between the
Routing Engines.
Ethernet switch—Provides 1-Gbps link speeds between the Routing Engine and
the IOCs.
Circuits for chassis management and control.
Power circuits for the Routing Engine and SCB.
LEDs—Provide status (see "SCB LEDs" on page 19).
