Chassis Components
This table lists the main components of the chassis.
Table 1: Main Components of the Chassis
Description
Component
These cards provide the intelligence of the system by functioning as the system
controller and providing route processing and chassis management. The RP cards
also monitor system alarms and control the system fans. The LEDs on the front
panel indicate active alarm conditions.
Route Processor Cards
(RPs)
The FCs provide the switch fabric for the routing system and performs the
cross-connect function of the routing system, connecting every LC to each other.
The switch fabric receives ingress user data from one LC slot and performs the
switching necessary to route the data to the appropriate egress LC slot.
Fabric Cards (FCs)
These cards provide the physical interfaces and optical connections for the user
data.
Line Cards (LCs)
The ECU provides all shelf electrical I/O connectivity to the active and standby
route-processor line cards. The ECU is located behind the craft panel.
External Connection
Unit (ECU)
The craft panel can install, configure, monitor, and troubleshoot the chassis
applications at the node and at the network level. The craft panel is located on top
of the ECU.
