Note
There are two air outlets on the rear of the NCS 4016. One is at the top behind the ECU and one is below the
bottom fan tray. For NCS 4009, there is one air outlet on the top of the chassis, below the power tray.
For more details of the chassis, see datasheet at

Description
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.
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.
These cards provide the physical interfaces and optical connections for the user
data.
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.
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.
4 Card cage containing:
• Nine LC slots - LC0 to LC8
• Two RP slots - RP0 and RP1
5 Four fabric card slots (FC0 to FC3) covered by
the inlet air filter
